Welcome aboard as we chart ten astonishing amazing sea survival stories that prove the ocean can be both a relentless adversary and a stage for human endurance.

Why These Amazing Sea Tales Inspire Adventurers

10 Pedro de Serrano

Pedro de Serrano is the original castaway hero. How his Spanish vessel vanished and why he alone washed ashore on a Caribbean island remain mysteries, but the legend says he arrived with only a knife clenched in his mouth and a shirt on his back.

The island was essentially a long, barren sandbar, offering little shade or vegetation. It was still the early New World—just half a century after Columbus’s voyages—so ships were a rare sight on the horizon. Serrano quickly learned that turtles were his lifeline: he hunted them for meat, used their shells to collect fresh water, and fashioned makeshift clothing when his own garments fell to rags. The only respite from the scorching sun was a plunge into the surrounding sea.

Three years later a wrecked ship drifted by, only to dash Serrano’s hopes of rescue when the survivor was tossed back onto his strip of sand. The newcomer, terrified at first, eventually became Serrano’s companion. The pair kept their sanity by imposing a strict daily schedule, sharing duties, and rationing the scarce turtle meat.

Tempers flared after four years together, and the two men split the island in half after an argument. Their separate halves endured until another ship finally stopped, rescued both men, and confirmed that the castaways were not the devils the sailors had feared.

9 Jeronimus Cornelisz

When the Dutch East India Company vessel The Batavia ran aground off western Australia in 1629, hundreds of survivors made it to a nearby island. Officer Jeronimus Cornelisz, who had previously attempted mutiny, seized command after the captain sailed for Java with a small party, promising to return.

Facing dwindling supplies and the threat of arrest, Cornelisz hoarded every salvaged provision and set a brutal regime. He dispatched groups in the ship’s lifeboat under the pretense of searching for water, but his true intent was to eliminate them. His plan was to hijack the rescue vessel and erase any opposition.

Soldier Wiebbe Hayes, leading a party that actually found food and water, uncovered Cornelisz’s murderous scheme. Hayes’s 45 men repelled the armed mutineers with slingshots and pikes, imprisoning Cornelisz in a beach pit. Undeterred, the remaining mutineers bombarded Hayes’s position until the promised rescue ship finally appeared on the horizon.

By the time help arrived, more than one hundred people had perished at Cornelisz’s hands. The rescue ended his reign of terror, but the tragedy left an indelible mark on the island’s grim history.

8 Robert Drury

In 1703 English sailor Robert Drury set sail aboard the merchantman The Degrave. After the ship was damaged near Madagascar, the crew abandoned her and reached shore, only to find themselves pursued by a force of roughly 2,000 Tandroy warriors.

Four harrowing days later the Tandroy captured the survivors. Every adult male was executed, but Drury and three teenage boys were spared and sold into slavery. Over the next eight years Drury served as a royal man‑servant, earning enough respect to fight alongside his captors. Eventually the Tandroy granted him limited freedom, allowing him to marry a fellow captive and raise cattle.

After nearly fifteen years of bondage, Drury slipped aboard an English slave ship and escaped Madagascar alone. His wife refused to leave, fearing a tribal myth that promised a cursed death to any runaway slave. Back in England, Drury struggled to reintegrate, and in a bizarre twist he later returned to Africa—not as a captive but as a slaver.

7 Philip Ashton

Philip Ashton was a 19‑year‑old fisherman off Nova Scotia in 1723 when pirates under Captain Ned Low seized his vessel. The pirates gave the crew a stark choice: join the buccaneers or die. Ashton chose the pirate life, though he never embraced the cruelty surrounding him.

Eight months later Low anchored near an island off Honduras to replenish fresh water. While the crew filled casks, Ashton slipped away, shouted “Coconuts!” and vanished into the jungle. The island was rich with fruit and tortoise eggs, a welcome bounty for a barefoot, empty‑handed maroonee.

After nine months of isolation a Spanish trader stopped by, leaving Ashton a knife and flint so he could hunt and cook for the first time since his capture. Seven more months passed before a group of sailors finally rescued him, ending his improbable escape.

6 The Crew Of The Peggy

American sloop The Peggy set out for New York in 1765 after trading in the Azores. A relentless November storm battered the vessel, snapping masts, tearing sails, and flooding the hull. With provisions exhausted, the crew even killed and ate the ship’s cat.

Captain David Harrison, bedridden from illness, tried to suppress talk of cannibalism, but by mid‑January the starving sailors had devoured all leather and candles. A grim lottery was staged, and the black manservant of the captain was slated as the first “sacrifice.”

The servant disappeared, and a second lottery named David Flatt as the next victim. Flatt earned a brief reprieve thanks to the captain’s desperate pleas. The following morning, a London‑bound ship arrived, delivering food, tackle, and a safe passage to London—just as the crew prepared a fire to cook the next unlucky sailor.

5 Robert Jeffery

Royal Navy sailor Robert Jeffery was 18 in 1807 when, after sneaking an extra drink of beer aboard the HMS Recruit, his captain—perhaps equally inebriated—marooned him on a rocky outcrop. The young sailor was left without food or water as his crewmates begged for mercy.

Nine days later an American ship rescued him, but the story was only beginning. Public outrage sparked a court‑martial, and in 1810 Jeffery was discovered living as a blacksmith in Massachusetts. His mother, still alive in England, became the focus of a national plea for reunion.

A Royal Navy vessel was dispatched, and when Jeffery finally returned home, church bells rang and crowds cheered. The captain who had abandoned him was later forced to pay reparations for nearly costing the young man his life.

4 Charles Barnard

Captain Charles Barnard’s sealing expedition near the Falklands in 1812 led him to a plume of smoke. Investigating, he discovered 45 shipwrecked British sailors. Barnard promised to ferry them to the nearest South American port on the condition they would not commandeer his vessel—an agreement made during the War of 1812.

While hunting pigs on a nearby island, the rescued British crew seized Barnard’s ship and sailed away, leaving the captain, his lone American companion, and three of the British sailors behind. The quartet endured 18 months on various islands, subsisting in a cramped rowboat.

A British ship finally rescued them in 1814. Mistaking them for Englishmen, Spanish authorities imprisoned the group off the coast of Peru. After months of legal wrangling, Barnard cleared his name, secured passage on another British ship, and was again set adrift in his seal boat. He later found an American vessel, sailed to China and the Sandwich Islands, and finally returned to America in 1816.

3 The Crew Of The Essex

In 1819 the whaling ship The Essex left Nantucket on a two‑and‑a‑half‑year voyage. After a violent storm damaged the vessel early on, the crew pressed forward. Months later, a massive sperm whale rammed the ship twice, creating a fatal hull breach. The crew abandoned ship in three whaleboats, each carrying scant provisions.

Fearing cannibals on the nearest land, the men steered south. Within weeks, the boats became leaky and food ran out. The first casualty was immediately consumed, followed by three more sailors who were cooked and eaten. One boat vanished without a trace.

The remaining two boats—one led by Captain Pollard, the other by First Mate Owen Chase—drifted apart. After 89 days at sea, Chase’s boat was rescued by an English vessel. Pollard’s crew drew lots; when his younger cousin was selected, Pollard offered to take his place. A week later, an American ship found Pollard and another crewman gnawing on the bones of their dead comrades. Decades later, Herman Melville met the captain who inspired Moby‑Dick, but their exchange was limited to polite conversation out of respect for Pollard’s ordeal.

2 The Other Survivors Of The Essex

After the whaleboats fled the wrecked Essex, the crew spotted the now‑known Henderson Island. Three men chose to remain ashore, hoping the island’s meager supplies would stretch their chances of rescue.

Rainwater collected in rock pools provided limited drinking water, but food was scarce. The survivors subsisted on crabs, resorted to drinking the blood of captured birds, and were haunted by the skeletal remains of earlier castaways.

Over 111 days the trio exhausted every resource. It was only because Owen Chase later signaled rescuers to search the nearby Pitcairn Islands that these men avoided certain death by thirst. Their grim tale underscores the razor‑thin line between survival and surrender on the open sea.

1 Bernard Carnot

Bernard Carnot, the son of a New Orleans innkeeper, was wrongfully convicted of murder and shipped to Devil’s Island in 1922, part of France’s brutal penal colony off French Guiana. The island was a nightmare of jungle disease, relentless mosquitoes, shark‑infested waters, and treacherous currents.

After sixteen years of imprisonment, Carnot vanished from the record—until American adventurer William Willis met his mother in New York. Moved by her story, Willis journeyed to South America, recruited ex‑convicts and current prisoners, and located the emaciated Carnot, who was barely alive in rags.

Willis secured a fake passport, money, and clothing for Carnot, then smuggled him aboard a supply ship bound for Brazil. Some accounts suggest that after his escape, Carnot joined the French forces under Charles de Gaulle and may have perished in action during World War II.

When the ocean shifts from a tranquil blue to an indifferent, endless expanse, even the hardiest sailors can end up adrift with a flimsy raft and a dwindling stash of supplies. The following ten harrowing survival accounts show how ingenuity, luck, and stubborn willpower can outlast the sea.

Harrowing Survival Highlights

10 Poon Lim

China‑born Poon Lim was working as a steward aboard the British merchant ship Ben Lomond when German U‑boat U‑172 torpedoed the vessel on the afternoon of 23 November 1942. The ship vanished beneath the waves in just two minutes, taking 53 of the 54 crew members with it. A non‑swimmer, Poon clung to floating debris for two harrowing hours before spotting a 2.4‑meter (8‑foot) raft bobbing nearby. The raft was stocked with biscuits, chocolate, sugar, flares, flashlights, smoke pots and a respectable 40 liters (11 gallons) of fresh water.

At first he survived on the rationed biscuits and chocolate, but those soon ran out. He quickly turned to the sea’s bounty, catching seabirds and fish—including sharks—using an improvised fishhook fashioned from a stray wire. He also fashioned a crude knife from the biscuit tin’s metal. To stay hydrated, he rigged a makeshift cover for the raft and collected rainwater whenever the skies opened. In moments of desperation he even sipped the blood of the birds and fish he had slain. Knowing his poor swimming ability, he tied a rope around his wrist and the raft to ensure he wouldn’t drift away if he slipped into the water.

After an astonishing 133 days adrift, a Brazilian fishing vessel finally sighted Poon’s lone raft and pulled him aboard. He remains the only recorded survivor to have spent that many days on a wooden raft. For his incredible endurance, King George VI awarded him the British Empire Medal, and the Royal Navy later incorporated his experience into a survival manual for its sailors. Poon eventually emigrated to the United States, where he became a citizen and lived out his days far from the seas that once tested his resolve.

9 Wilbert Widdicombe And Robert Tapscott

On 30 October 1940, British sailors Wilbert Roy Widdicombe and Robert George Tapscott washed ashore on Eleuthera in the Bahamas after surviving a grueling 70‑day ordeal at sea. Their nightmare began when the merchant ship Anglo Saxon was torpedoed off the African coast by the German cruiser Widder on the night of 21 August 1940. While the enemy vessel fired at two life rafts, Widdicombe and Tapscott slipped into a small, quiet boat that escaped notice.

Their fellow survivors fared poorly: two succumbed to machine‑gun wounds, another pair went mad and leapt overboard, and a third cut his throat with a razor. The scant provisions they had lasted a mere 15 days. After that, they subsisted on seaweed and whatever fish they could catch, supplementing their diet with distilled water and the alcohol contained in their compass.

Two ships passed them during their odyssey, yet neither crew spotted the desperate duo. When they finally reached the Bahamas, both men were blackened by the relentless sun, their hair matted into thick clumps, and Tapscott was so weakened that he could no longer walk. In a desperate attempt to eat his shoes, Widdicombe broke his front teeth. Their story stands as a stark reminder of the brutal reality faced by those left to the mercy of the ocean.

8 Jose Salvador Alvarenga

On 17 November 2012, Mexican fishermen Jose Salvador Alvarenga and his companion Ezequiel Córdoba set out from Costa Azul on a modest 7‑meter (23‑foot) boat for what was supposed to be a 30‑hour fishing trip. Within days, towering 5‑meter (16‑foot) waves and gale‑force winds exceeding 100 km/h (60 mph) battered their vessel for five relentless days. When the storm finally eased, they had lost all food, their engine sputtered to death, their radio fell silent, and they found themselves adrift some 450 km (280 mi) from the Mexican coast.

Survival hinged on raw fish and seabirds. Córdoba’s lips swelled to double their size, and his skin became riddled with salt‑induced sores. He once ate a seabird whose stomach harbored a sea‑snake, nearly poisoning himself. After that harrowing encounter he refused to eat any more raw birds and subsisted on triggerfish and turtles. By day 23, Córdoba was hallucinating, begging Alvarenga for oranges, and pleading that if he died his body not be eaten but tied to the front of the boat. He even contemplated suicide by leaping into a shark‑filled shoal. Córdoba finally perished on day 118; Alvarenga claims he buried the body at sea, treating it as if still alive for several days.

Against all odds, Alvarenga drifted for 438 days—nearly 9,000 km (5,600 mi)—before finally washing ashore on the Marshall Islands on 30 January 2014. Though many in Mexico doubted his tale, oceanographers and medical experts verified its authenticity. Still, Alvarenga faced a lie‑detector test, and Córdoba’s family sued him for $1 million, accusing him of cannibalism.

7 Captain Jukichi, Hanbe, And Otokichi

On 4 November 1813, a Japanese trading vessel captained by Jukichi set sail from Edo (modern‑day Tokyo) toward Shizuoka when a sudden storm tore the helm and mast from the ship. The crippled craft was left to drift helplessly for an astonishing 484 days before being rescued off the California coast on 24 March 1815. Of the original crew, only three survived the ordeal: Captain Jukichi, Hanbe, and Otokichi. Twelve others succumbed to scurvy.

The trio survived on purified seawater and the bags of soybeans they were transporting. Their arrival in the United States sparked curiosity, as they became the first Japanese individuals ever to set foot on American soil during a period when Japan’s isolationist policies barred foreign entry. Hanbe later died on the return voyage to Japan, leaving Jukichi and Otokichi as the sole survivors.

Captain Jukichi’s return to Japan was celebrated; he was even granted the rare privilege of adopting a surname—a distinction typically reserved for the elite. To this day, Jukichi, Otokichi, and Hanbe hold the record for the longest documented period spent adrift at sea.

6 Vidana, Rendon, And Ordonez

On 28 October 2005, a five‑man fishing party departed San Blas, Mexico, on what was supposed to be a routine outing. Disaster struck when one engine seized and the other ran out of fuel, leaving the boat dead in the water. Stranded, the men resorted to a grim diet of raw birds, fish, and even sharks, which they sometimes caught with their bare hands. They fashioned a fishhook from the disabled engine’s parts and collected rainwater in a bucket to stave off dehydration.

Two of the fishermen died during the ordeal, unable to tolerate raw meat. Their bodies were left aboard the vessel, and the remaining three—Jesus Vidana, Lucio Rendón, and Salvador Ordoñez—pressed on for 285 days, guided only by ocean currents. Eventually, a fishing boat near the Marshall Islands spotted their craft on 8 August 2006 and rescued them.

Back home, the trio faced a maelstrom of accusations: skeptics claimed they must have cannibalized their dead companions because they appeared too healthy after nine months at sea, and others suspected them of smuggling cocaine, as San Blas is a known drug‑transit hub. Both Vidana and his companions denied all allegations, maintaining that sheer survival instinct and ingenuity saw them through.

5 Maurice And Maralyn Bailey

In March 1973, British couple Maurice and Maralyn Bailey were on a trans‑Atlantic voyage from the United Kingdom to New Zealand when a massive whale rammed into their yacht just off the coast of Guatemala on 4 March. The impact forced the couple to abandon ship and inflate a rubber dinghy, stuffing it with whatever they could salvage before the yacht sank. With limited provisions, they soon turned to turtles, birds, and fish for sustenance.

Maralyn’s mother had been receiving postcards from the Baileys at each port of call; the last arrived in February 1973 when the couple passed through the Panama Canal. When the postcards stopped, her mother grew alarmed, but no one else noticed the couple’s plight. Over the next two months, the dinghy’s seams began to split, requiring constant reinflation, while sharks circled menacingly and two severe storms battered the tiny craft. The dinghy capsized three times, leaving the Baileys exhausted and battered.

Finally, on 30 June 1973, a Korean fishing vessel spied the struggling dinghy and pulled the couple aboard after 117 days adrift. They were sunburned, severely malnourished, dehydrated, and riddled with sores. Their stomachs had atrophied so much that they could not eat solid food for two days, underscoring the extreme toll of their ordeal.

4 Nalepka, Glennie, Hofman, And Hellriegel

On 4 June 1989, a sudden, towering wave capsized the yacht Rose‑Noelle at around 6 a.m., flipping it upside down. Four New Zealanders—John Glennie, Rick Hellriegel, Jim Nalepka, and Phil Hofman—clambered onto the overturned hull and endured roughly four months beneath the sea’s surface. Initially, New Zealand authorities launched a search, only to call it off when the vessel’s trajectory remained a mystery. The Water Safety Council eventually listed the quartet as dead.

Against all odds, the men survived. Ocean currents should have carried the vessel toward Chile, yet it drifted toward Great Barrier Island. Their clean clothing and lack of sores raised suspicion among officials, prompting customs to investigate possible drug smuggling. Nevertheless, forensic analysis confirmed the yacht had indeed been sailing upside down, and the men had fashioned a cramped shelter inside the hull’s overturned interior. They supplemented their dwindling supplies with fish they caught, and when they finally reached shore, they discovered an empty cottage where they could finally clean up and change into fresh clothes.

3 Jennifer Appel And Tasha Fuiava

On 3 May 2017, Honolulu‑based adventurers Jennifer Appel and Tasha Fuiava set sail with their two dogs, aiming for Tahiti in what should have been an 18‑day voyage. A sudden storm allegedly flooded their engine, leaving them adrift for an astonishing 176 days until the U.S. Navy rescued them on 25 October. Their rescue sparked a media firestorm: oceanographers questioned the existence of the storm, and shark experts noted that tiger sharks—cited by the duo—rarely attack vessels.

Compounding the mystery, all six of the boat’s communication devices reportedly malfunctioned, and the pair never activated the Emergency Position‑Indicating Radio Beacon (EPIRB), a device that could have signaled their location to rescuers. Appel claimed they chose not to turn on the EPIRB because they felt they had enough provisions and believed they would eventually reach land. Later, they altered their story, alleging a Taiwanese fishing boat had rammed them and its crew attempted to kill them.

The controversy deepened when a tabloid unearthed nude photographs of Appel from a decade earlier. Insurance companies also refused to cover the vessel, citing that it had strayed over 640 km (400 mi) from shore—beyond the range for coverage. Even their families distanced themselves, leaving the pair to navigate the aftermath of their extraordinary—and heavily disputed—seafaring saga.

2 William And Simonne Butler

On the night of 15 June 1989, a pod of whales—estimated between 200 and 500—rammed the sailing vessel of William and Simonne Butler roughly 2,200 km (1,400 mi) from Panama. The colossal impact sent their boat to the ocean floor within fifteen minutes, leaving the couple clinging to a rubber raft. Their emergency kit included a knife, a water desalinator, a fishhook, a flashlight, two blankets, three flares, 38 liters (10 gal) of water, and a Sony Walkman that miraculously picked up radio stations from Los Angeles, Texas, Guatemala, Costa Rica, and Panama as they drifted.

Food supplies lasted only four weeks, after which the Butlers resorted to eating turtles and triggerfish. Sharks constantly prowled the waters, eyeing the fish they hid beneath the raft. At one point, porpoises joined the sharks, and one porpoise even tore a hole in the raft’s underside. The couple finally signaled a passing ship with their last flare; the vessel ignored them, but a Costa Rican Coast Guard cutter arrived the following day to rescue the exhausted pair.

Both William and Simonne emerged from the ordeal severely weakened: each had lost 23 kg (50 lb). Simonne’s legs felt as soft as cotton, while William bore a painful cut on his right hand and sores across his back. Their story underscores the sheer physical toll that weeks at sea can exact.

1 Toakai Teitoi

On 27 May 2012, Kiribati native Toakai Teitoi traveled from Maiana to Tarawa to be sworn in as a police officer. After his ceremony, he watched a film about four Kiribati men who vanished at sea for six weeks—an ominous foreshadowing. Determined to return home, Teitoi set off with his brother‑in‑law Ielu Falaile aboard a small boat that should have taken only two hours.

Instead, a sudden loss of fuel after a night of fishing and sleeping left them adrift in the open ocean. While they possessed food, they lacked water. After weeks of hardship, Falaile succumbed to dehydration and died on 4 July. A heavy storm on 5 July brought torrential rain, enabling Teitoi to fill two 19‑liter (5‑gal) containers with fresh water.

On the afternoon of 11 September, a shark struck the hull of Teitoi’s boat, providing an unexpected rescue signal. The shark’s presence attracted a nearby fishing vessel, which ultimately saved Teitoi. He believes the shark’s bump was his lifesaver, allowing him to survive a total of 108 days at sea.

When we think of archaeology, we often picture dusty dig sites on solid ground. Yet the real treasure trove lies beneath the waves, where 10 artifacts discovered by daring explorers reveal stories of empires, myths, and lost civilizations.

10 Artifacts Discovered Beneath the Waves

1 Port Royal

Life in 17th‑century Port Royal, Jamaica, pulsed with the swagger of pirates, the clamor of bustling markets, and the rapid growth of a colonial outpost that existed for barely 37 years before disaster struck.

On June 7, 1692, at precisely 11:43 a.m., a massive earthquake followed by a tsunami swallowed two‑thirds of the harbor, sending the city to its watery grave.

Underwater archaeologists later uncovered a treasure trove of artifacts preserved in the low‑oxygen depths, offering a pristine snapshot of daily life in the notorious pirate haven.

Excavated structures, undisturbed streets, and even intact furnishings have illuminated the social fabric, commerce, and architecture of this once‑vibrant port.

I love medicine, writing, and challenges. I am eagerly looking forward to attending medical school in the near future, finally fulfilling my lifelong dream of becoming a physician. I also love to express myself through my writing, and I believe that one of the best ways to grow as a person is to take on challenges and learn from them. I am a passionate advocate of making mistakes and building on one’s skills and talents to take the world by storm.

2 The Underwater Temple In Lake Titicaca

Cradled in the high Andes between Bolivia and Peru, Lake Titicaca has long been a cradle of civilization, and in the year 2000 a daring international team dove into its depths to unearth a hidden sanctuary.

The submerged temple measures an impressive 200 m by 50 m and dates to roughly 1,000–1,500 years ago, a period associated with the Tiwanaku culture that pre‑dated the Incas. Its stone and gold relics, along with extensive roadways and agricultural terraces, hint at a far‑reaching complex far beyond initial expectations.

3 The Seven Pagodas Of Mahabalipuram

Along the Tamil‑Nadu coastline, the Shore Temple of Mahabalipuram stands as a testament to ancient Indian architecture, and legend speaks of seven grand pagodas that once glittered there.

Myth tells that jealous deities unleashed a tsunami, drowning six of the temples and leaving only the Shore Temple visible above water.

In a recent expedition led by best‑selling author Graham Hancock, divers located the submerged remnants of one of the lost pagodas offshore, uncovering foundations, broken pillars, steps, and scattered stone blocks that confirm the ancient accounts.

This discovery not only expands our knowledge of Mahabalipuram’s maritime heritage but also validates stories passed down through generations, bridging myth and archaeology.

4 The Lost City Of Helike

Among the glittering city‑states of ancient Greece, Helike once shone as a thriving hub on the north‑west Peloponnesian peninsula, only to vanish dramatically in 373 BC.

Natural forces—perhaps an earthquake‑triggered tsunami—obliterated the city, and it lay hidden for centuries. Rediscoveries in the 19th and 20th centuries sparked debate, but it wasn’t until 2001 that a well‑preserved site emerged beneath an inland lagoon, sealed by a thick silt layer.

By 2012, archaeologists finally stripped away the silt, confirming Helike’s location. Legend still whispers that Poseidon, patron god of the sea, exacted vengeance on the city, adding a divine twist to its tragic fate.

5 The Antikythera Shipwreck

Off the island of Antikythera, Greece, a Roman vessel rested 55 m (180 ft) beneath the waves until advanced underwater technology in 2015 allowed divers to explore its cargo after more than two millennia.

Among the recovered treasures were a bronze armrest possibly from a throne, a delicate bone flute, ancient board games, fine ceramics, an ornate lagynos (table jug), and, most famously, the Antikythera mechanism—a sophisticated clockwork device used to predict astronomical events.

6 Remnants Of Gondwana

According to a November 2011 National Geographic feature, colossal fragments of the ancient supercontinent Gondwana—once comprising present‑day India, Australia, and Antarctica—have been recovered from the ocean floor.

Scientists identified continental rocks such as granite, gneiss, and sandstone, alongside fossilized remains, confirming a direct link to the massive continental breakup that began roughly 130 million years ago. These findings continue to reshape our understanding of Earth’s geological past.

7 The Oldest‑Known Submerged Town

Discovered in 1968 by Dr. Nic Fleming, the sunken Bronze‑Age settlement of Pavlopetri lies off Greece’s southern Laconian coast, initially dated to around 2000 BC.

Modern sonar and 3‑D mapping have pushed its age back to an astonishing 5,000–6,000 years, making it the oldest known submerged town. The site was first identified through a unique assemblage of Neolithic pottery.

Protected by natural geological barriers, Pavlopetri remains remarkably preserved, and ongoing investigations aim to reveal further secrets of this ancient maritime community.

8 The City Of Dwarka

Off the western coast of India lies the legendary submerged city of Dwarka, known as the “Gateway to Heaven” and believed to have been constructed under the guidance of Lord Krishna and the divine architect Vishwakarma.

Krishna, the eighth avatar of Vishnu, is said to have descended to Earth to restore peace and prosperity, commissioning this magnificent urban center.

Archaeological surveys have uncovered evidence of human habitation dating from the 15th–16th centuries BC. Mythology recounts that after Krishna’s departure, the city was swallowed by the sea, forever preserving its sanctity.

Today, pilgrims and scholars from around the globe journey to the site, drawn by its spiritual resonance and the enduring allure of Hindu mythology.

9 Egyptian Artifacts Of Thonis‑Heracleion And Canopus

In the year 2000, French underwater archaeologist Franck Goddio and his European Institute for Underwater Archaeology team uncovered roughly 250 Egyptian artifacts near the western Nile Delta, linked to the sunken cities of Thonis‑Heracleion and Canopus.

These treasures shed light on the once‑prosperous metropolises that vanished in the 8th century AD, enriching our grasp of Egyptian mythology, especially the cult of Osiris.

Further research suggested a canal connecting the two cities to ancient Alexandria, and the finds were showcased in Paris from September 2015 to January 2016.

10 Artifacts From The Roman Empire

In October 2014, a team of divers off Italy’s coast located the wreck of a 2,000‑year‑old Roman ship, previously detected but only fully explored after the dive.

The vessel measured 15 m (50 ft) in length and likely served as a merchant or military transport, its cargo revealed by terra‑cotta pots that once held olive oil and wine.

Named Panarea III, the ship sailed between Rome and Carthage between 218 BC and 210 BC, offering valuable insight into Mediterranean trade routes and everyday Roman life.

Between 1276 and 1178 BC, a loose coalition of marauding seafarers—collectively remembered as the Sea Peoples—swept across the eastern Mediterranean, leaving a trail of devastation that still fuels scholarly debate. These Bronze‑Age raiders, often likened to the later Vikings for their ferocious raids, set their sights primarily on Egypt during its opulent New Kingdom era, striking at both coastal towns and inland strongholds. The 10 fascinating theories about these ancient marauders are explored below, each shedding light on a different facet of their enigmatic legacy.

10 Fascinating Theories Explored

10 The Philistines

Often painted as the arch‑villains of the Old Testament, the Philistines made their home along the southern fringe of what is now Israel, encompassing the modern Gaza Strip. After establishing a string of fortified settlements, they forged a confederation of city‑states that included Gaza, Ashkelon, Ashdod, Gath, and Ekron, creating a political bloc that could rival their Israelite neighbors.

Their expansion beyond the coastal strip inevitably clashed with the Israelites, prompting biblical authors to demonize the Philistines and even turn their deities—most famously the fish‑god Dagon—into literal demons. The biblical narrative also cast them as the backdrop for larger-than‑life figures such as the giant Goliath, whose defeat by the diminutive David became a timeless tale of underdog triumph.

Beyond the scriptural accounts, the Philistines appear in a variety of contemporary sources, including Syrian, Phoenician, and Egyptian correspondence. While the consensus leans toward classifying them as one of the Sea Peoples who settled the region, their precise origins remain a hotly debated topic among scholars.

One prevailing hypothesis situates the Philistines in the Aegean world, with many specialists arguing they were Mycenaean Greeks who migrated westward. Excavations near ancient Gath have uncovered pottery shards that bear a striking resemblance to Mycenaean ceramics, and a distinctive red‑and‑black ceramic figurine—resembling a bear—has been interpreted as evidence of Mycenaean cultural influence on the Philistines.

9 The Sardinian Connection

The mortuary temple of Medinet Habu, dedicated to Ramses III, houses the most iconic Egyptian relief depicting the Sea Peoples in battle. The stone carvings differentiate the various groups by their distinctive headgear, offering a visual catalogue of the invading forces.

Among the most eye‑catching figures are warriors wearing horned helmets, a style that scholars associate with the Sherden—one of the nine groups named in Egyptian records. Because Egyptian chroniclers were primarily concerned with documenting their victories, they left little behind regarding the Sherden’s homeland.

Nevertheless, a body of archaeological and textual evidence points toward a Sardinian origin. Researchers link the Sherden to the island’s Nuragic civilization, known for its stone towers (nuraghe), fortified dwellings, and elaborate burial complexes. Bronze‑Age figurines from Sardinia depict warriors sporting the same horned helmets seen in the Egyptian relief, bolstering the case for a Sardinian identity.

8 The Sicilian Connection

In the wake of the Sea Peoples’ upheavals, the island of Sicily was divided among three principal tribes: the Elymians, the Sicani, and the Siculi (also called the Sicels). While the Sicani were indigenous, the Elymians are thought to have migrated from Asia Minor and maintained strong ties to the Aegean Greek city‑states.

The Siculi, on the other hand, were likely an Italic people who crossed over from the Italian mainland. All three groups may have connections to the broader Sea Peoples phenomenon, with Egyptian sources naming the Sicilian marauders as the Shekelesh.

Greek historians later suggested that the Siculi fled to Troy after being repelled by Egyptian forces, traveled through southern Italy, and finally settled in Sicily. Modern scholarship tends to support this narrative, recognizing the Siculi and Elymians as displaced members of the Sea Peoples confederation who found refuge on the island.

7 The Etruscans

The Etruscans, who flourished in northern and central Italy, remain one of antiquity’s most enigmatic peoples. Their script and language are only partially deciphered, forcing historians to rely heavily on Roman accounts and the vibrant tomb frescoes the Etruscans left behind.

Ancient Greek thinkers were already debating the Etruscans’ origins. Some linked them to the Pelasgians—an Aegean tribe speaking a Mycenaean dialect—while the Roman historian Dionysius of Halicarnassus argued they were autochthonous to Italy. The most popular ancient tradition, voiced by Herodotus and later Virgil, claimed the Etruscans originated in Lydia (western Anatolia) and arrived in Italy under the leadership of a king named Tyrrhenus.

Intriguingly, one of the Sea Peoples groups was the Teresh, occasionally referred to as the Tyrrhenians. This connection fuels a theory that the Etruscan ancestors were Greek pirates who first seized Lydia, were later expelled by famine, and ultimately settled in Italy, explaining the striking religious parallels between the two cultures.

6 Connection To The Balkans

While the majority of Sea Peoples appear to hail from the Aegean or broader Mediterranean basin, several scholars argue that groups from the Adriatic also joined the migration. Austrian historian Fritz Schachermeyr, in a 1982 study, suggested that the Sherden and Shekelesh were originally Adriatic peoples with ties to the ancient Illyrians.

The Illyrians formed a tribal confederation that spanned much of today’s Croatia, Slovenia, Montenegro, Bosnia, Serbia, and Albania. Evidence indicates that some Illyrian tribes settled parts of the Italian peninsula, intermarrying with local Italic populations. Recent research from Vienna University has also clarified that Illyrian language did not directly give rise to modern Albanian, dispelling a long‑standing myth.

Although Schachermeyr’s hypothesis is not mainstream, a faction of scholars continues to argue that a severe famine in the Balkans forced Illyrian groups—and perhaps other Adriatic peoples—to embark on both land and sea migrations, ultimately joining the Sea Peoples’ sweeping movements.

5 The Battle Of Troy

The legendary clash chronicled in Homer’s *Iliad*—the protracted siege of Troy—features three principal Greek factions: the Danoi, the Teucrians, and the Achaeans. Egyptian records, such as the Great Karnak Inscription and the Merneptah Stele, refer to these groups as the Denyen, the Tjeker, and the Ekwesh, respectively, hinting at a possible Sea Peoples connection.

Scholars have long debated whether Homer’s epic preserves a historical memory of a real war between a Mycenaean coalition and the inhabitants of Troy, who may have been ancestors of the Etruscans. The Hittite Tawagalawa letter, addressed to the king of Ahhiyawa (believed to represent Mycenaean Greece), mentions a conflict over Wilusa—widely identified as Troy—suggesting diplomatic and military entanglements between the Hittites and the Aegean world.

Archaeological evidence from western Turkey supports the notion that Bronze‑Age Greeks established city‑states in close proximity to Hittite territories, reinforcing the plausibility that the *Iliad* reflects a distant echo of actual geopolitical struggles involving the Sea Peoples.

4 The Minoan Connection

While many scholars place the core of the Sea Peoples in mainland Greece, some argue that Crete’s Minoan civilization also contributed raiders to the confederation. The Minoans have been linked to the Egyptian‑named groups Tjeker and Peleset, both listed among the Sea Peoples.

Before the Late Bronze Age Collapse, the Minoans maintained extensive trade networks with Egypt and the Levant. Egyptian Amarna letters refer to Crete as “Caphtor,” a major power that suffered repeated Sea Peoples attacks. It is plausible that Minoan sailors, alongside Mycenaean colonists settled on Crete and Cyprus, joined the raiding parties in search of livestock, treasure, and slaves.

3 The Dorian Invasion

Although many attribute the Sea Peoples’ movements to sheer opportunism, a minority of historians propose that they were fleeing a larger onslaught in their homelands. Carl Blegen of the University of Cincinnati suggested that Mycenaean Greeks were displaced by a Dorian invasion originating from the mountainous southern peninsula.

The Dorian hypothesis draws on ancient Greek myth, particularly the tale of the Heracleidae—the descendants of Hercules—who allegedly launched a war to reclaim their ancestral lands. Proponents argue that this invasion forced Mycenaean city‑states to collapse, prompting their inhabitants to join the Sea Peoples in search of new territories.

From this perspective, the victorious Dorians, speaking a Doric dialect, imposed their language on post‑Mycenaean Greece, ushering in the so‑called Greek Dark Age. While the archaeological record for a massive Dorian migration is sparse, the theory offers a compelling narrative for why the once‑prosperous Mycenaean centers fell.

Critics point out the lack of definitive material evidence, but the Dorian invasion remains an influential, if contested, explanation for the broader pattern of upheaval that characterised the end of the Bronze Age.

2 A Greater Indo‑European East

Given that many Sea Peoples appear to have originated in Europe, some scholars view their eastward thrust as part of a larger Indo‑European migration wave. It is plausible that the confederation comprised speakers of diverse Indo‑European tongues, ranging from Mycenaean Greek to various Italic dialects found in Italy and Sicily.

The extent of their permanent settlements remains debated, but evidence suggests a simultaneous land‑based migration from both Europe and Asia Minor. Some researchers even entertain the notion that groups from as far north as the Carpathian Mountains joined the movement, while others link the Lukka—one of the named Sea Peoples—to the Lydians or Luwians, both Indo‑European peoples of western and central Anatolia.

Historical records from the Anatolian kingdom of Kizzuwatna (today’s southwestern Turkey) indicate a mixed population of Phoenician and Mycenaean settlers. Moreover, Hittite annals reference earlier Indo‑European incursions, such as the campaigns of Attarsiya, a Mycenaean general who helped establish the Ahhiyawa kingdom and launched raids into Cyprus and Hittite vassal states like Arzawa.

1 Outsized Influence On Greek Mythology

Some scholars argue that Homer’s *Iliad* preserves a faint echo of an actual war between the Mycenaean kingdom of Ahhiyawa and the Hittite Empire. Likewise, *The Odyssey* recounts the arduous journey of Odysseus after the Trojan conflict, hinting that these epic poems may encode collective memories of Sea Peoples‑era migrations.

For example, the myth of Zeus battling the monstrous Typhon likely derives from Cilicia, a Hittite‑controlled region in southern Anatolia. Prior to Mycenaean collapse, Greeks are believed to have settled in Cilicia, absorbing local legends about a thunder‑god defeating a sea‑born dragon, which later morphed into the Zeus‑Typhon narrative.

Similarly, the tale of Teucer—a Trojan hero who supposedly settled on Crete and Cyprus before voyaging to Phoenician cities like Sidon—may reflect a mythic retelling of Mycenaean colonists traveling eastward after the Sea Peoples’ upheaval. These stories suggest that Greek mythology contains veiled references to real‑world migrations and cultural exchanges during the Bronze Age collapse.

Benjamin Welton, a freelance writer based in Boston, has contributed to publications such as *The Weekly Standard* and *The Atlantic*. His research into the Sea Peoples continues to spark conversation among historians and enthusiasts alike.

Deep sea saturation diving pushes the boundaries of human endurance, with divers living for weeks in pressurised habitats to avoid the dreaded bends. Yet even the most seasoned professionals can fall victim to the ocean’s unforgiving extremes. Below, we dive into the 10 deep sea incidents that still send shivers down the spines of anyone who hears their stories.

10 Deep Sea Accidents Overview

This roundup walks you through each tragedy, from catastrophic decompression failures to high‑pressure nervous syndrome, highlighting the human cost and the lessons learned. Strap in – the water’s colder than you think.

10 Byford Dolphin Accident

The Byford Dolphin mishap remains one of the most harrowing deep‑sea calamities on record. In 1983, the North Sea‑based drilling rig Byford Dolphin was bustling with activity when two divers slipped into its diving bell – a pressurised transport chamber used to ferry workers down to the work site.

During a routine shift, another pair of divers were already settled in a decompression chamber, while the first pair prepared to move into their own compression unit. Unfortunately, the tenders – the “drivers” responsible for securing the bell – neglected to fully seal the bell from the chambers before initiating the ascent.

The result was a sudden, violent decompression: pressure plummeted from nine atmospheres to a single atmosphere in an instant, ejecting air from the chambers. Three divers inside were killed by explosive decompression, their blood‑borne nitrogen bubbles expanding so rapidly they essentially boiled from within. A fourth diver was ripped from a narrow opening, his internal organs expelled, and a fifth diver in the bell also perished.

9 Wildrake Accident

In August 1979, the MS Wildrake, a support vessel operating on a North Sea oil rig, became the stage for a chilling tragedy. Two American commercial divers, Richard Walker and Victor Guiel, boarded the diving bell for a routine excursion.

Mid‑descent, the bell’s lift wire snapped, leaving the chamber stranded at roughly 525 feet (160 meters) beneath the surface. Deprived of power and heat, the bell’s occupants faced a hostile environment.

Rescue crews battled for nearly a full day, but by the time the bell was finally hoisted, both divers had succumbed to hypothermia, their bodies unable to withstand the relentless cold.

8 DOF Subsea Accident

While many deep‑sea catastrophes unfold in the North Sea, a 2017 incident off Australia’s northeastern coast proved that danger knows no borders. DOF Subsea Australia dispatched a team of divers to service an underwater pipeline at depths ranging from 778 to 885 feet (237‑270 meters), marking one of the deepest Australian saturation dives on record.

Unfortunately, the company failed to supply the appropriate gas mixes for such extreme depths. Upon surfacing, the divers reported vivid hallucinations, tremors, and cognitive disturbances—symptoms that had even manifested while they were still on the seafloor.

Medical investigation pinpointed high‑pressure nervous syndrome (HPNS), a condition triggered by breathing helium at great pressure. Though the symptoms were reversible and no permanent injuries were recorded, DOF Subsea was later ordered to compensate the divers for its negligence.

7 Drill Master Accident

The 1974 Drill Master tragedy unfolded off Norway’s coast, claiming the lives of two seasoned commercial divers, Per Skipnes and Robert John Smyth. While inside their diving bell at a depth of 321 feet (98 meters), a critical component—the drop weight—malfunctioned and released unexpectedly.

This sudden loss of ballast propelled the bell skyward toward the surface. Complicating matters, the bell’s bottom hatch remained ajar, allowing a rapid pressure shift as the bell surged upward.

The abrupt decompression proved fatal: both divers suffered decompression sickness and ultimately drowned, a grim reminder of how a single mechanical failure can cascade into disaster.

6 Star Canopus Accident

In 1978, the Star Canopus dive off Scotland’s coast turned from routine to catastrophic within moments. Divers Lothar Ward and Gerard Prangley entered the diving bell for a standard operation alongside the Beryl Alpha platform.

During descent, a loose anchor sliced through the drop wire, life‑support line, and guide cables. Deprived of controlled lowering, the bell plummeted to over 328 feet (100 meters).

A frantic rescue effort finally retrieved the bell after a grueling 13‑hour wait, but both divers had already perished—one from drowning, the other from hypothermia.

5 Stena Seaspread Accident

The 1981 Stena Seaspread incident unfolded in the North Sea when divers Phil Robinson and Jim Tucker found themselves over a hundred metres beneath the ocean’s surface, freshly completing work on an oil rig.

Unbeknownst to them, powerful tides had severed the umbilical cords feeding air and pressure to their diving bell, leaving the chamber dead‑air dead.

Surface teams quickly recognised the emergency and initiated a rescue. Realising the bell’s pressure loss could trigger decompression sickness, they deployed a second bell to the same depth, transferred the two divers, and safely brought everyone to the surface without injury.

4 Venture One Accident

The 1977 Venture One disaster began as divers Dave Hammond and Craig Hoffman prepared to lower a blow‑out preventer to 525 feet (160 meters). While Hammond worked on the rig, Hoffman waited inside a chamber within the diving bell.

Suddenly, an odd electrical hum crackled over the radio. Hammond rushed back, only to find Hoffman floating unconscious outside the bell. He hauled his partner back inside and attempted resuscitation, but Hoffman had already drowned.

Post‑mortem analysis suggested Hoffman had likely slipped out of the bell without his mask, inhaled water, and succumbed to drowning.

3 Waage Drill II Accident

In 1975, divers Robert Edwin and Peter Holmes embarked on a short‑range mission off Scotland’s coast, descending to 394 feet (120 meters) to untangle rope entanglements on a rig.

After completing the task, they returned to their bell for decompression, only to discover a persistent gas leak. Unable to seal the leak, they moved into a deeper attached chamber. Their supervisor, attempting to counteract the leak, pumped helium into the chamber.

Because the internal gauge malfunctioned, the supervisor over‑compensated, flooding the chamber with excess helium. This caused the pressure to drop to the equivalent of 650 feet (200 meters) while the temperature spiked to a scorching 120 °F (48.9 °C). The extreme heat rendered breathing impossible, and after several hours, both men succumbed to hyperthermia.

2 Bibby Topaz Accident

The 2012 Bibby Topaz incident provides a rare glimmer of hope amid tragedy. Diver Chris Lemmons was engaged on a subsea drilling structure when the vessel’s positioning system malfunctioned, drifting 625 feet (190 meters) off‑course.

Although Lemmons escaped the structure unscathed, his umbilical cord—supplying air, hot water, and communications—became snagged, leaving him stranded on the seafloor in total darkness.

Back on the surface, the crew quickly re‑established position, realised the emergency, and within 40 minutes retrieved Lemmons, returning him safely to his bell and providing medical care. He survived, and the Bibby Topaz subsequently overhauled its safety protocols.

1 Johnson Sea Link Accident

The 1973 Johnson Sea Link tragedy unfolded off Key West when a submersible was dispatched to assist in sinking an artificial reef.

Onboard were divers Edwin Link and Albert Stover, alongside the vessel’s pilot. While descending, the craft became ensnared in the wreckage of the very destroyer it was meant to survey.

Rescue teams eventually raised the submersible, but while the pilot survived, both divers perished from carbon‑dioxide poisoning within the trapped vessel.

Hundreds of people set sail each day, whether for fishing, warfare, or a host of other motives. Yet, not every mariner who embarks on the great blue ever makes it back. Here are ten hapless sailors who mysteriously disappeared at sea.

10 Hapless Sailors: The Lost Legends

10 John Cabot

Giovanni Caboto, an Italian-born navigator circa 1450, only turned his sights toward exploration around 1495. Unable to secure Spanish backing, he Anglicized his name to John Cabot and petitioned the English crown for support.

King Henry VII agreed to fund his ventures, and Cabot launched a successful voyage that took a more northerly route than Columbus five years earlier. After twenty days at sea he sighted land, mistakenly believing it to be Asia, and christened it “New Found Land”—today’s Newfoundland. Though he found no gold, he noted abundant cod, claimed the territory for England, and soon returned home.

A year later, on a second expedition, Cabot’s fortunes changed. Around 1498 he set out again, aiming to chart a westward passage to Asia, sailing with five ships. After that departure, records fall silent.

Historians still debate whether Cabot perished on the ocean or reached an unknown shore without chronicling his journey. For now, his final expedition is considered a loss at sea.

9 Vasco de Ataíde

Vasco de Ataíde, a Portuguese sailor, joined Pedro Cabral’s 1500 expedition to India. While the overall venture succeeded, Ataíde never reached his intended destination.

He captained one of Cabral’s vessels, which set sail from Cape Verde along Africa’s western coastline in late March 1500. That departure marked the last sighting of his ship.

Neither Ataíde nor his crew of roughly 150 men were ever seen again. Curiously, contemporary logs record no storms or strong winds that might explain the disappearance, leaving his fate shrouded in mystery.

8 Real

Born around 1450 in Portugal, Gaspar Corte-Real was driven by the era’s spirit of adventure. In 1500 he embarked on a westward voyage under the Portuguese crown, seeking new lands.

His first foray took him to Greenland, but icy conditions prevented a safe landing, forcing a return to Portugal. Undeterred, he raised funds for a second expedition the following year.

Again thwarted by Greenland’s ice, he pressed farther south to Labrador, where he captured several Indigenous individuals to transport back to Portugal. While two of his three ships later reached London, the third—carrying Gaspar—never arrived, and his disappearance remains unresolved.

7 Real

Miguel Corte-Real, brother of Gaspar, was spurred into action after his sibling’s 1501 disappearance. Determined to locate Gaspar, Miguel assembled three vessels and a crew for a rescue mission in 1502.

The expedition initially succeeded, reaching the area where Gaspar had been sighted. The fleet then split to increase search coverage, agreeing to reconvene on August 20th to share findings.

When the rendezvous date arrived, Miguel’s ship was nowhere in sight. With no trace of his vessel or crew, he was eventually declared lost at sea.

6 Diego de Nicuesa

Diego de Nicuesa, a Spanish explorer, earned royal commissions that sent him to Santo Domingo in 1502 and later to Panama and Costa Rica, where he governed colonies.

By 1510, unrest sparked by famine and disease prompted Nicuesa to quell a rebellion. Upon arrival, the colonists detained him and seventeen crew members, loading them onto a vessel bound for Santo Domingo.

The craft never reached its destination; it vanished somewhere in the open sea, and neither Diego nor his men were ever seen again.

5 Francisco de Hoces

Francisco de Hoces, a Spanish military officer, joined the 1526 Loaísa Expedition to the Spice Islands, commanding the ship San Lesmes among seven vessels.

The fleet initially made good progress into the Pacific, but powerful gales soon battered them. During one such storm, the San Lesmes disappeared without a trace.

Scholars speculate the vessel may have been blown eastward toward Easter Island or even New Zealand, but evidence is scant. The waters where the ship vanished are now known as the Drake Passage or Mar de Hoces, cementing his loss at sea.

4 Roche Braziliano

Roche Braziliano, a fearsome pirate active from 1654, earned a reputation for cruelty, even threatening to shoot anyone who refused a drink.

After a relatively successful piratical career, his story ends abruptly in 1671 when he and his entire crew vanished without a trace.

No contemporary records explain the disappearance—whether the ship capsized, was captured, or succumbed to another fate remains speculation. To this day, Braziliano is counted among the lost at sea.

3 Dirk de Lange

Dirk de Lange captained the merchant vessel Ridderschap van Holland, a ship built for East Indies trade. While most voyages were successful, a fateful 1694 expedition ended in mystery.

Departing for Indonesia on the ship’s fifth journey, de Lange stopped briefly at the Cape of Good Hope before pressing onward. After leaving the cape, the vessel vanished without a trace.

Historians debate the cause: some suggest pirate capture, others propose a capsizing off Western Australia. Regardless, the ship and its crew remain unrecovered.

2 John Coxon

John Coxon, a buccaneer who terrorized Santa Marta, Colombia, began his pirating career around 1677, raiding Caribbean settlements for years.

In 1688, after receiving a pardon from Jamaican authorities, Coxon disappeared. Despite extensive searching, no definitive clues emerged about his fate.

Some crew testimonies noted his ship was unusually heavy, hinting that the overloaded vessel may have sunk, sealing his mysterious end.

1 Michel de Grammont

Michel de Grammont, born circa 1645 in Paris, started as a nobleman before a fatal duel forced him into piracy. He set sail in 1670 aboard the ship Hardi.

His raids spanned numerous Spanish forts—including Trujillo, Gibraltar, La Guaira, Cumana, Veracruz, and Puerto Cabello—earning a reputation for daring assaults.

In April 1686, Grammont joined fellow French pirate Nicolas Briguat on a rescue mission. When Briguat was captured, Grammont set out to free him, but a violent storm intercepted his fleet, and he and his crew vanished forever.

Everyone loves a sunny day at the beach, feeling the warm sand between their toes and the salty breeze on their skin. Yet, beneath those sparkling waves lies a world that’s anything but a postcard—welcome to the realm of the 10 creepy gruesome sea dwellers that make the ocean feel like a midnight thriller.

While the surf offers playful dolphins and majestic whale‑watching, the deep blue also shelters some of the most unsettling and oddly fascinating critters on Earth. From bizarre body plans to shocking hunting tricks, these ten terrifyingly weird marine animals prove that the sea is a place of both wonder and eerie wonderment.

10 creepy gruesome Sea Creatures Overview

10 Sarcastic Fringehead

The sarcastic fringehead, also known as a tube benny, makes its home along the northeast Pacific coastline, nesting in burrows or tube‑like shelters—some even claim they’ve been spotted in discarded soda bottles. These fish are fiercely territorial; males tend to guard the homes, prompting females to deposit their eggs inside the males’ lairs.

Females have turned this into a competitive showdown: two males will flare their enormous mouths—four times larger when opened—to see who can claim the bigger gape. The fish with the smaller opening bows out, abandoning the contested spot. It’s a literal “big mouth, big ego” scenario playing out underwater.

Despite their intimidating appearance, sarcastic fringeheads feast on tiny planktonic morsels such as squid eggs. Their secretive burrow lifestyle keeps them largely out of fishermen’s nets, and their stealthy existence helps protect them from extinction. So, while they may look like miniature monsters, they’re more shy neighbor than sea‑monster menace.

9 Northern Stargazer

Scientifically dubbed Astroscopus gottatus and nicknamed the Popeye fish, the northern stargazer dwells on the ocean floor with a flat, spotted body and a head that seems designed for espionage. Its eyes, nostrils, gill slits, and most of its mouth perch atop its skull, and oddly enough, it draws water in through its nostrils rather than its mouth.

Weighing up to 20 pounds and stretching about 22 inches, this ambush predator buries itself in sand, exposing only its eyes and a gaping maw to snap up unsuspecting fish and crustaceans. Adding to its menace, a specialized organ on its head can discharge up to 50 volts, making it one of the ocean’s electrifyingly dangerous residents—and it’s also venomous.

8 Deep Sea Dragonfish

Deep sea dragonfish inhabit the abyssal zones around 5,000 feet deep, especially in the northern and western Atlantic and the Gulf of Mexico. Their slender, black bodies are lined with razor‑sharp fang‑like teeth, and despite their fearsome look, adults only reach about six inches, with females typically larger than the diminutive males.

These fish are bioluminescent masters, generating light through a chemical reaction that can illuminate their entire form. They flash this glow to lure prey—or potential mates—into the inky darkness, then snap up small fish and crustaceans. Their dark‑lined stomachs help conceal the luminescent meals they digest, ensuring they stay hidden from predators even while feasting.

7 Gulper Eel

The gulper eel, a strange denizen of tropical and temperate seas, earns the nickname “umbrella mouth” thanks to its cavernous jaws that can open wider than its own body. Its loosely hinged, pelican‑like mouth can engulf prey whole, storing the catch in a lower jaw pouch.

Equipped with tiny, light‑sensing eyes and a long, pink‑tinged tail that ends in a luminous bulb, the eel doesn’t chase its meals. Instead, it uses that tail‑light to attract crustaceans, snapping them up with its massive mouth. Adults can reach three to six feet in length, though most of that measurement is tail, making them an unsettling sight in the deep.

6 Fangtooth Fish

Living more than 16,000 feet beneath the surface, the fangtooth fish is a nocturnal hunter that sometimes rises toward the surface under the cover of night. Its defining feature is a set of long, needle‑sharp teeth that line a disproportionately large mouth, allowing it to seize scarce prey in the dark.

Unlike many deep‑sea denizens, the fangtooth lacks a bioluminescent organ, relying instead on an acute sense of smell to locate food. Despite its terrifying dentition, it maxes out at around seven inches, making it more of a miniature terror than a genuine threat to humans.

5 Frilled Shark

The frilled shark resembles a living fossil, sporting a seven‑foot, eel‑like silhouette with fins tucked far toward its rear. Its rows of trident‑shaped teeth are perfect for snagging soft‑bodied prey such as squid, and it can swallow its catch whole regardless of size.

It propels itself with a serpentine, eel‑like swimming motion, rarely encountering humans due to its deep‑water habitat. Occasionally caught as by‑catch, some are even harvested for food, which has contributed to concerns about its conservation status.

4 Angler Fish

Over 200 species of angler fish call the dark depths—beyond 900 meters—of the Atlantic and Antarctic Oceans home. Their massive, crescent‑shaped mouths are lined with translucent, razor‑sharp teeth, and adults can grow up to three feet long.

Females possess a modified dorsal spine that dangles like a fishing pole, glowing to lure prey that can be twice their own size. Males are dramatically smaller, barely reaching eight inches, and they permanently attach themselves to females, shedding all organs except testes—effectively becoming a living sperm factory. A single female may carry several males at once.

3 Giant Isopod

The giant isopod, a massive crustacean related to shrimp and crabs, has roamed the oceans for over 160 million years. Its seven pairs of sturdy legs and armored exoskeleton allow it to curl into a protective ball, much like its terrestrial cousin the pillbug.

Residing on the deep‑sea floor, these creatures live in a state of semi‑hibernation, conserving energy by limiting movement and respiration. Their impressive size results from abyssal gigantism, and they can survive for up to four years without food, feasting voraciously when a carrion feast becomes available.

2 Goblin Shark

The goblin shark, often hailed as one of the ocean’s most eerie inhabitants, sports a long, protruding snout packed with electro‑receptive organs that detect faint electric fields in the dark. Its coloration ranges from a ghostly pink to a muted purplish‑gray, with striking blue edging along its fins.

When prey approaches, the goblin can thrust its jaws forward at remarkable speed, snapping up fish, squid, and crustaceans. Fully grown adults can reach an astonishing 16 feet, making them one of the largest and most formidable deep‑sea sharks.

1 Vampire Squid

Neither a true squid nor an octopus, the vampire squid boasts eight arms and two slender filaments, its name inspired by its dark hue and a cape‑like web that drapes between its arms—reminiscent of a nocturnal vampire’s cloak. When threatened, it flips this web over, exposing spiny, poisonous hooks on the underside.

Feeding on detritus and microscopic organisms, the vampire squid employs sticky cells on its tentacles to capture particles rather than hunting aggressively. Instead of ejecting ink, it releases a bioluminescent mucus to confuse predators, and each arm tip can emit light for communication.

The ocean is home to a vast array of life forms on a scale most of us will never appreciate. Over 226,000 of them have been identified, but it’s estimated there may be up to 1 million different creatures lurking down there. The internet is rife with lists of some of the most unusual, but they often repeat themselves and pick creatures we’ve all seen before like goblin sharks or gulper eels. Weird, for sure, but also well known. Lucky for us, there are still thousands and thousands more to choose from. Here’s ten of the strangest. 

10. Duobrachium sparksae

No one will accuse Duobrachium sparksae of having an easy to pronounce or remember name, but until someone coins a better one, that’s all we have. It’s a kind of comb jelly and it was only discovered in the waters near Puerto Rico back in 2015. 

The little critter survives in very deep waters, about 3,900 meters below, and it resembles a sort of living bubble. Scientists remarked, with the long tendril-like appendages hanging off of it, it looks a bit like a hot air balloon. When viewed from the tentacle side, it looks like a box. 

The central blob actually has two arms from which much longer tentacles can extend. The retractable tentacles are 12 to 22 inches in length and root the creature to the sea floor, helping to control its position. 

9. Mariana Snailfish

Deep sea life is always interesting because the environment is about as alien as it can possibly get on our planet. The creatures that live beyond where even light can penetrate and where pressure would crush us to smithereens are often incredibly and unusual to our eyes. And scientists have discovered what they think may be the deepest living fish of all – the Mariana Snailfish. 

Inhabiting the deepest part of the ocean, the Mariana Trench, you can see these fish yourself if you can make the journey down 26,000 feet. They grow to under a foot in length and have translucent skin and no scales. 

Their diet seems to consist of tiny crustaceans that also make their home at depth and, as you’d expect, they don’t have to endure a lot of predators at that depth. 

8. Pink See-Through Fantasia

There’s no way an animal that managed to snag the name “pink-see-through fantasia” is anything but weird, so rest easy that this one lives up to its name completely. In fairness, the proper name for his deep sea cucumber is enypniastes and some people will also call it the headless chicken fish, so you have some choice.

The cucumber uses bioluminescence to ward off predators and has transparent skin. That ensures that its mouth, stomach and anus are all visible no matter what angle you’re looking at it from. It’s also fairly small, ranging from four inches to just nine inches in length. 

You’re not likely to find this creature in your own travels. It hangs out at depths around 2,500 meters although they have a range of about 1,000 meters up and down through the water column. They use tiny webbed fins to swim and use little tentacles to push sediment into their mouths to eat. 

7. Pyura chilensi

Amazingly, this curious creature isn’t one of these new, bizarre discoveries of the last few years. This creature, a tunicate, was actually first described back in 1782. And it’s just as weird to most people today as it was back then, simply because it looks like a rock that has guts and blood inside of it.

The pyrua chilensi doesn’t just look like a rock, it lives like one, too. It can’t move anywhere on its own, so it just filters water, sucking it in and feeding on microorganisms along the way. How does an immobile rock monster reproduce? Well, they’re all born male, but part of the way through life they become hermaphrodites and just breed with themselves, shooting both sperm and eggs into water around it until they meet, fertilize, and germinate into a new living rock. 

Despite the creepy appearance, people actually eat them, and you can cook them or enjoy them raw. Enjoy might be a bit of a stretch though, since the taste is described using words like “bitter,” “iodine,” and “soapy.”

6. Zombie Worms

The deep sea osedax, also known as the zombie worm, has no mouth or anus and drills into whale bones. That’s a pretty intense resume for anything living on land, sea or air. Despite not even having a digestive tract let alone a mouth, these mysterious worms wait for whale fall, which is what happens when a whale dies and then sinks to the bottom of the sea. They then latch onto the corpse. Their flesh secretes acid, which allows them to bore right into the bones. Once inside, a symbiotic bacterial process allows for the digestion of fats and enzymes that the worms then absorb. It’s not the easiest way to get a meal, but it works for them. 

If none of that was weird enough, then know that the worms you can see are always female. Males remain in the larval stage their entire lives, living in a slime tube that encases the female, and existing solely to fertilize her eggs when the time comes. 

5. Beehive Shrimp

The idea of animals living in colonies or hives is very common up here on the surface. Ants, bees, termites and many more live in this way where one queen seems to rule the roost and the rest of the colony serves her needs. They call this eusociality and it’s only been observed in one marine species – a shrimp known as Synalpheus regalis. 

These tiny shrimp live in coral and sponges and come in a variety of bright colors. They’re snapping shrimp, which means they have one giant claw and one little claw to make them look either intimidating or hilarious depending on your perspective.

Like any good hive society, the shrimp have a queen. Colonies can grow to over 300 members, but there is only one female capable of reproduction. Hive members care for the young, protect their colony from predators, and work in a communal way to accomplish tasks. 

4. Stubby Squid

Discovering a new species is exciting for anyone in the scientific community and traditionally those of us who just have a passing interest in animals just hear about it secondhand. But the stubby squid is one creature whose discovery you can actually watch first hand on video since it was recorded by researchers on the E/V Nautilus back in 2016. And this may be the only time in history that we’ll ever know of for sure when a new species’ discovery was accompanied by laughter from everyone involved because the animal looked so goofy.

You can hear the crew puzzle over what the little creature might be, then laugh as they zoom in and point out that it looks like it has googly eyes. The tiny creatures are between 0.3 inches and 3 inches in length, which accentuates just how funny the eyes look since they’re so large relative to the rest of it. 

3. Phronima

Phronima is the name of a terrifying but blessedly small ocean parasite that some believe inspired the alien queen from the movie Aliens. Right away that’s a creepy thought for any living thing, but in both looks and behavior the phronima scores big points for being monstrous.

The parasites are found almost everywhere on earth in the oceans, except in polar waters. Unlike other, similar species, phronima swim in open waters instead of waiting for food to find them on the sea floor. This is because they’re on the hunt for a ride. 

Phronima, which have dangerous if tiny claws, hunt down other creatures called salps. A salp is a barrel-shaped tunicate that, for all intents and purposes, looks like a small, living piece of Jell-O. A phronima will hunt down a salp and use its claws to hollow out the inside, then move right in. 

The phronima can now sail the seven seas, protected inside their sort-of living boat, eating and drinking and reproducing as they go. Somehow, the salp, which is a peculiar life form to begin with, doesn’t fully die despite being hollowed out. The outer cells stay alive, so the whole salp boat structure maintains its shape and protects the phronima inside.

As far as the link to Alien goes, the story seems to be wholly anecdotal. That said, there are some convincing side by side photos that suggest the alien queen, rather than HR Giger’s original alien, may have been inspired by the little monster. 

2. Pigbutt Worm

How do you make a list of strange sea creatures and not include one that is legitimately named the Pigbutt Worm? If that sounds too uncouth for you, you can use its alternate name “flying buttocks.”

Discovered in 2007, the pigbutt worm is a worm but it’s round, the size of a hazelnut and yes, it looks like a flying butt. It floats about around 3,000 to 4,000 feet below the surface and their tiny mouths are caked in mucus to complete the image in your mind. 

Nearly every other species of worm closely related to the pigbutt lives in a tube, so this free-floating bum is a standout on its family tree. The working theory is that they float around in clouds of detritus and tiny bits of bio-matter and then eat whatever sticks to their mouth mucus. 

1. Giant Siphonophore

The word “giant” sets up some expectations and when we’re talking about the ocean, there’s a standard to live up to. This is the home of the blue whale, the largest creature that has ever existed, after all. So if there’s something in the sea called a giant siphonophore, it better be impressive. Luckily, the name isn’t just smoke and mirrors, this thing really is huge. It’s not as bulky as a blue whale by any means, but it’s no slouch.

There are nearly 200 kinds of siphonophores in the sea and describing them isn’t all that easy in layman’s terms. To start with, they’re colonial organisms, which means it’s not “a” thing, but a group of things. But they’re not all the same things. Different parts have different functions. There’s a sort of “main” part that you might consider a head, and then other parts that develop independently which can help the whole organism eat or swim or digest and other such functions. Think of it a bit like a deep sea Voltron, several small parts that are assembled to make a functional whole. 

The giant siphonophore is about as thick around as a broom handle. Not so giant at all. However, it can also grow to be upwards of 130 feet long. That makes it one of the longest creatures in the world by a longshot, only having to compete with the bootlace worm which has been observed to grow slightly longer. That said, one that was seen off the coast of Australia was estimated to be about 150 feet long. 

Lucky for those of us who are not giants, the giant siphonophore is relatively harmless and feeds on small crustaceans and other animals which can best be described as gelatinous. It uses bioluminescence to attract its prey and uses a toxin similar to that employed by jellyfish to poison its prey. That part does sound dangerous, but you need to remember that these are deep sea creatures. They actually can’t exist near the surface and their bodies will burst if they are brought up to surface pressure.

Ocean cities. Settlements in seas. Famed writer Jules Verne was on to something with “Propeller Island,” after all.

In this account, we explore some of the most ingenious ways in which human settlements have taken a marine form that thrive in modern times, while paying respects to some real-life versions of Atlantis found below the waves.

10. MS The World

The brainchild of Knut U. Kloster, MS The World is remarkable and globally unique condo at sea. With everything from sports facilities to a grocery store, this “largest residential yacht on the planet” is an apartment ship with 165 residential apartments, in total measuring 644 feet, 2 inches long and 98 feet wide. A board of directors elected by the residents, plus committees, plan out the ship’s travel routes, budgeting and on-board activities, along with shore stops.

The attractive vessel is a place to reside, with its fully livable apartments that range from its little studio residences to middle ground studio one or two-bedroom apartments, regular two-bedroom apartments, all the way up to three-bedroom suites with a full range of amenities. One to three expeditions (typically informed by 20 or more relevant experts, for planning) take in culture, scenery, and natural history of places like Madagascar, the British Isles/Hebrides, and the Northwest Passage.

9. Kansai International Airport

A masterpiece of Japanese engineering, Kansai Interntional Airport, opened in 1994, is an airport in the middle of the sea. Well, in the middle of Osaka Bay, offshore of Japan’s main island, Honshu, to be exact. Originally planned to be floating, the airport was instead built on sand, creating a runway-shaped construction surrounded by water, with all the amenities expected at an airport.

The airport is connected to Honshu by a narrow strip for rail and road transport, and has been judged as an engineering disaster due it its history of sinkage into the soft sands and mud of Osaka Bay and the subsequent costs. The airport nevertheless received recognition as an American Society of Civil Engineers “Civil Engineering Monument of the Millennium” award recipient in April 2001. The airport notably weathered a 120 mile-per-hour typhoon in 1998 and survived the 1995 Kobe earthquake without destruction despite the thousands of deaths on Honshu.

8. Jules’ Undersea Lodge

While not quite a full city or even a town, Jules’ Undersea Lodge is a most unique hotel that requires SCUBA certification for guest access. Located in Florida, the structure is located 21 feet below the waves. Celebrity visitors to the lodge have included Aerosmith lead singer Steven Tyler and former Prime Minister of Canada Pierre Trudeau.

The lodge itself is located in a mangrove environment with 42-inch windows while hot showers, music and movies, beds with a view of wild fish outside, and a kitchen containing a microwave and fridge are present in the lodge. A variety of stay packages ranging from just a few hours to a full overnighter are available, along with dive training if the required certification is not already held by visitors.

7. Palm Islands

The United Arab Emirates is a land home to some of the world’s most remarkable feats of marine engineering. Take the Palm Islands, a set of stunning marine archipelagos with rays and centerpieces that can be most fully appreciated from aerial views or space photographs. The islands include Palm Jumeirah, a precisely palm leaf shaped archipelago, Palm Deira Island, and Palm Jebel Ali, located along the Dubai coastline. Started in 2001, the developments contain a vast array of dwellings and commercial buildings constructed on the rays and stems. Breakwaters protect the construction works on the islands.

The project scale was most impressive. The first of the Palm Islands, Palm Jumeirah, utilized a whopping 3 billion cubic feet of sand, dredged from the Persian Gulf, built into the palm shape with GPS, while mountain rock totaling seven million tons was used to form the seven-mile breakwater protection system. Near the Palm Islands are two more human-made archipelagos, The World, named after its construction in the likeness of a map of the Earth, and The Universe, built to resemble the Milky Way Galaxy.

6. Neft Dashlari (Oily Rocks)

Extending from overturned scrapped tankers and connected by trestles and pipes is an expansive ghost city in the Caspian Sea. Located off the coast of the Republic of Azerbaijan, Neft Dashlari, or Oily Rocks, is one of the strangest urban areas on the planet. A ramshackle yet industriously constructed network of oil drilling facilities, stores, and apartment buildings stands bizarrely perched throughout the settlement. Neft Dashlari gained the amenities of an entire town including stores, educational facilities, and homes, plus libraries and service centers. Dormitories with five stories and hotels were among the grander structures built.

The community was literally built on top of overturned ships, which serve as building foundations. The site holds the Guinness World Record for being the first ever offshore oil platform. Neft Dashlari is now largely abandoned, with only some settlement remaining. A dark episode in the history of Neft Dashlari was the perhaps less than surprising, with the disappearance of three workers following the collapse of living accommodations into the Caspian Sea.

5. The Boat City of Aberdeen Harbour

Hong Kong, a special administrative region of China, has a complicated cultural history. Aberdeen Harbour exists in stark contrast to the towering and densely clustered skyscrapers for which Hong Kong is famous. Here in the harbor, there are large congregations of boats on which dwellers live and work. Restaurants are included in the amenities offered by the “boat city,” adding significantly to the tapestry of the village as a unique attraction.

Despite some viewing the floating neighborhood as a visual disturbance, the boat city is gaining an established place in Hong Kong’s culture. Movie depictions of Hong Kong make good use of the boat city for both panoramic views and as the setting for great action scenes. In historic times, the pirate life of the boat city was colorful, to say the least.

4. Ko Panyi

https://www.youtube.com/watch?v=fwSsOpOni7s

The image is incredible. One of Thailand’s most fascinating sights is the aerial view of Ko Panyi. With multi-colored roofs, the buildings of the village on stilts extend outward in a rough question mark shape around the base of a precipitous stony island, formed from a single mini-mountain that rises from Phang Nga Bay. Ko Panyi is in southern Thailand’s Phang Nga Province on the Malay Peninsula, between the Thai border with Myanmar to the north and Malaysia to the south.

A testament to the resourcefulness of its founders, Ko Panyi was established by Toh Baboo, friends and family who were Muslim ocean travelers who arrived around 200 years back but were unable to settle on land as foreigners upon arrival in Thailand. Today, the 300 families numbering almost 1,500 individuals live in the village that clusters around the rock. Dwellings, restaurants, a mosque, and even a floating football pitch are among the features of the village.

3. Fadiouth, Senegal

In the African nation of Senegal, a section of coastline known as Petite Côte is a village of fishers that is divided between a land-based section of settlement, Joal, and a much stranger island portion of the village, Fadiouth. Joal-Fadiouth’s two sections are connected via a wooden footbridge, 1,312 feet in length. Fadiouth is bizarre because it is on an entirely human-made island, and that island is made from discarded yet rather precisely placed seashells.

Over the last century (and more), villagers have been toiling at a two-fold project. On one hand, they have been harvesting marine mollusks for food, and on the other, casting the shells aside. This has created the huge midden that grew into the island supporting Fadiouth. Fastened by mangrove roots and other coastal wetland plants, the shell island resists the tides. The theme everywhere is shells. The famous cemetery is made of shells, while streets and buildings sport shells. The population is Christian and Muslim and is known for its close community held together by residential embrace of religious diversity.

2. Halong Bay Floating Villages

Vietnam is home to a spectacular floating village group that has achieved world recognition for its cultural and architectural uniqueness. Amongst pillar-like mountains that emerge from the waters of Halong Bay are four floating villages comprised of multiple buildings on rafts that form a fishing community. The four villages in Halong Bay contain 1,000 villagers and are named Cua Van, Ba Hang, Vong Vieng, and Cong Tau.

Designated as a UNESCO World Heritage Site, the villages provide a base for fishing lobster, shellfish, finned fish, and squid. Larger vessels resemble land-based houses in their design, while smaller boats are moored to the dwelling boats, which can themselves move around or anchor to neighboring dwellings to allow convenient forays through the bay. The largest village, Cau Van, hosts the Floating Cultural Center, which seeks to preserve the villages under the auspices of the Ha Long Ecological Museum.

1. Urban Rigger

A floating apartment is a novel concept and even more-so when the apartment complex is made of upcycled structures. The Urban Rigger project in Copenhagen, Denmark is just such a remarkable development, with 72 studio apartments for students fashioned from shipping containers. Floating by the shoreline in the Copenhagen neighborhood of Refshaleoen, the project was designed by Bjarke Ingels Group after being first dreamt up by original founder Kim Loudrup, who encountered great challenges in finding his son student housing in Denmark.

Students appreciate the sustainable, livable design of the mini community on the water, the first residents having arrived in 2018. The shipping containers that make up the apartments focus on making the best use of natural light and are fitted with their own bathrooms and kitchens, while common areas include gardens, a gym, and laundry facilities. Residents can go for a swim right from their doorstep.

Mankind has been creating boats for about 8,000 years now. The earliest boats were either rafts or canoes and obviously pretty simple in their construction and function. If you’ve ever seen a modern super-yacht or aircraft carrier you know how significantly the times have changed. But the path from ancient raft of reeds strapped together up to your modern aircraft carriers is far from a straight line. There have been a number of curious twists and turns along the way.

10. SS Baychimo

You may not have heard of the SS Baychimo but it’s one of the most unusual ships in all of naval history. The thing that makes it unusual is the fact that, as of right now, no one even knows where it is.

Launched in 1914 by the Hudson Bay Company, the SS Baychimo was originally named Ångermanelfven after a river in Sweden, where it was built. It was a massive vessel that weighed 1,322 tons and was over 200 feet long. It was used throughout the Arctic of Canada to deliver provisions after the war. Prior to that it made runs from Sweden to Germany.

In 1931 it got trapped in the ice off the coast of Alaska. The crew left the ship and walked to the nearest town. Later, as the weather grew worse, storms ravaged it and at one point the temperature went from -60 all the way up to zero. When the crew went to check on the ship trapped in the ice they discovered it no longer was trapped. It just wasn’t there anymore.

Over the next several decades the ship was sighted again and again, sailing as a ghost ship across the ocean. It was last seen in 1969, nearly 40 years after it had been set loose to do its own thing.

Because it’s been so long since it’s been seen most people assume it sank some time ago, but no wreckage has ever been found and the path it managed to wander through the oceans was one that spanned hundreds of miles. So it’s entirely possible that it’s still out there somewhere. 

9. Project Habakkuk

During the Second World War, the British planned to create an aircraft carrier unlike any that had ever been seen before. Called Project Habakkuk, it wasn’t a vessel created from steel or wood; it was to be a 2,000 foot long vessel made from a substance called pykrete. Pykrete is what happens when you mix wood pulp into water and then freeze it. The result is even stronger than concrete. Bullets ricochet right off it. The entire vessel would be one giant, dirty ice cube.

While Habakkuk never came to fruition for the British in the war, a test version of it was constructed in Canada. Set into Lake Patricia in Alberta, Canada, the scale model was 60 feet long and weighed 1,000 tons. A 1-horsepower motor was used to keep it frozen. The project was eventually abandoned due to numerous impracticalities.

8. The FLIP Buoy 

The Floating Instrument Platform, or FLIP, is what happens when you want to have both a boat and a buoy at the same time and can’t decide between the two. It’s a research vessel on which scientists will spend weeks at a time doing studies on the open water. And while in motion it’s a ship that’s over 355 feet long, when it’s ready to do work the ballast tanks fill with water down three hundred feet of its entire length, causing it to flip forward at a right angle until only the habitable end is sticking up out of the water.

With three hundred feet of vessel under the water and just the last 50 ft floating above, it’s able to weather nearly any kind of rough seas without a risk of flipping over or sinking. The length of the vessel is well below the water that is disturbed by surface waves, so it’s simply bobs calmly on top of the water.

When the research is done, compressed air is forced into the ballast, the water drains out, and the boat flips back into position so that it can sail home again.

7.  The Plongeur Submarine

The French Plongeur submarine has a special place in history. It was the first submarine that was able to propel itself through mechanical power. First launched in 1863, you can imagine how terrifying it must have been at that time to trust a machine to take you under the water and somehow keep you alive.

Earlier subs had been powered by human energy — crews pedaling to keep the ship moving like an underwater bicycle. The Plongeur had a compressed air-powered engine and was far larger than anything before it. At 140 feet long, the ship also contained 23 tanks of compressed air which took up 403 cubic feet of space. 

The Plongeur made several successful journeys before it was decommissioned, mostly out of fears of its unstable design, it’s limited air supply, and the fact that technology improved enough to make better vessels 

6. Camel Supply 

If you’ve ever wondered how camels travel the world, then wonder no longer. The tale of the USS Supply, the most uncreatively named supply ship in US Naval history, can answer that question for you. 

In 1855, US Secretary of War Jefferson Davis crafted a mission to acquire camels so that the US Army could have a camel division. The goal was to have camels to navigate deserts in Mexico. The thinking was clearly that since camels were adapted to desert climates in the Middle East, they could handle desert climates in North America just as easily and give soldiers an upper hand. 

A 60 foot long camel barn was constructed on the USS Supply. By 1865 the ship had reached the Middle East and was loaded down with 33 camels from different regions of the Middle East to see which would adapt best to life in North America. 

It took 87 days to get back to America and inexplicably, despite leaving with 33 camels, they arrived home with 34 since a new one had been born along the way. Camels adapt well to ocean travel. A second trip brought back 41 camels.

The USS Supply had proven its worth as a camel carrier, but the camels themselves ended up being a failure as they adapted poorly to combat, they smelled terrible, and they had rather unpleasant attitudes if they didn’t like the person who was handling them. 

5. The Hughes Glomar Explorer

While the idea of a covert spy ship doesn’t seem that unusual, the Hughes Glomar Explorer was the CIA‘s clever attempt to retrieve a sunken Soviet vessel without anyone having any idea what was going on. The plan was for it to sneak in and snag a Soviet nuclear sub and then take off again without any outward sign that anything that ever happened.

The Explorer was originally built after a Soviet ballistic missile nuclear sub sank at the height of the Cold War. The Soviets were unable to determine exactly where the sub had gone down so they couldn’t salvage it themselves. Then the US Navy discovered it. 

The top secret construction of the vessel proved to be one of the strangest missions the CIA has ever conducted. The final product was so large it couldn’t even fit down the Panama Canal. The front and back ends of the ship were meant to bob and weave on waves while the center remained stable. The reason for that was it was essentially one of those giant claw machines you see in supermarkets. The plan was to grasp the sunken submarine some 17,000 feet below the surface of the ocean and make off with it. The ball bearings were apparently the size of bowling balls. 

Even more impressive than the construction was the fact that this all had to be done super secretly. Obviously the Soviets would not have approved if word got out, so the CIA came up with a cover story. Billionaire Howard Hughes designed the ship so he could farm manganese nodules at the bottom of the ocean. Front companies were set up and stories were leaked to the press. 

The ruse worked for a time, but the claw apparatus broke and then the cover story was blown. They never actually managed to retrieve the sub, but it was an impressive effort. 

4. USS Wolverine 

Most everyone knows what an aircraft carrier looks like. They’re the largest vessels on the sea and weigh upwards of 40,000 tons. It’s hard to imagine, then, that there was a second kind of aircraft carrier designed for use in freshwater. The Great Lakes had their own aircraft carriers, including the USS Wolverine. It was originally a side paddlewheel steamer that transported people from Cleveland to Buffalo. 

The Navy purchased the vessel in 1942 and set it up as a freshwater training aircraft carrier in the Great Lakes. It had none of the armaments that a normal carrier is outfitted with, and was smaller than a modern carrier, but it saw extensive use as a training vessel for pilots. In fact, over 17,000 pilots trained to land and take off from the Wolverine during the Second World War. 

3. HMS Zubian

During the First World War the Royal British Navy had two Tribal-Class warships known as the HMS Zulu and the HMS Nubian. Both vessels were badly damaged in 1916 but not destroyed. So, in a feat of naval ingenuity, the front of the Zulu was welded onto the back of the Nubian to create a brand new vessel – the HMS Zubian.

Despite being a Frankensten vessel, the Zubian saw extensive service during the war and proved its worth more than once. It even managed to sink a German U-Boat in 1918. The threat of submarines was so great the Navy couldn’t afford to lose any ships if they could avoid it, and forging a new ship from two old ones was more cost-effective and faster than starting from scratch.

2. Baron of Renfrew

We live in what some people call a disposable culture these days. Everything from razors to coffee pods are designed to be used and tossed out. That seems normal to us, but the idea of a 304 foot long wooden ship, the largest wooden ship ever built, being built to be tossed out still seems a little odd.

The Baron of Renfrew was built as a single use vessel. It was a little bit of a scam, meant to ship timber from the New World to Europe. The ship itself would be taken apart when it got where it was going and the wood that was used in its construction would be tax exempt because it was part of the ship, as opposed to the cargo. Things didn’t go quite as planned and the ship started taking on water. Timber washed up on shore in France, having almost reached its destination.

1. Ramform Titan

When you need to measure seismic activity or do surveys at sea the Ramform Titan is the ship on which to do it. Shaped like a giant wedge of cheese, the Titan has an insanely powerful engine that produces 26.4 megawatts of power. For some perspective, a giant wind turbine produces about two megawatts of power, which is enough to power about 400 average homes. So the engine here could power over 5,000 homes.

The massive design is meant to be stable in any weather, so crews could safely work even in the middle of a storm at sea. The vessel is capable of running survey streams behind it, 24 in total, that can span well over 100 kilometers in length. In fact, in 2015 they ran 129.6 kilometers of streamers during a survey, breaking a world record.
