When it comes to the 10 bizarre shark lineup, most people can name at least a few shark species, such as the famous great white, tiger sharks, and perhaps the biggest fish in the ocean—whale sharks. However, that is only the tip of the iceberg.

Sharks come in many different shapes and sizes, with roughly 440 species in the world today. And that number only continues to grow, with the latest species, named “Genie’s Dogfish,” discovered in July 2018.

Here are some of the most unusual shark species discovered so far.

10 Bizarre Shark Overview

10 Zebra Shark

Zebra sharks can be found in the western Pacific and Indian Oceans as well as the Red Sea. Divers often mistake this species for the leopard shark due to its similar black dots on a tan body. But the resemblance can only be seen on mature sharks, which have shed the yellow stripes they are born with.

With a flexible body that easily wriggles into tight spaces and whisker‑like sensory organs called barbels at the front of its snout, the zebra shark has a body perfectly adapted for hunting in areas that other predators struggle to reach.

These sharks prefer to live in tropical waters and shallow reef habitats. There, they feed on crabs, sea urchins, small fish, snails, and other small invertebrates that like to hide in caves and narrow crevices.

In the absence of suitable partners, zebra sharks have been observed to reproduce through parthenogenesis (aka “virgin birth”). Scientists are still not sure why some sharks, snakes, and other creatures, which usually require a mate to reproduce, sometimes get pregnant spontaneously. For example, in 2017, a zebra shark named Leonie laid eggs that hatched three pups despite not being around a male shark in three years.

Due to its prized meat, zebra sharks are under threat of extinction in many of their endemic territories. They are sold fresh or salt‑dried in markets across Malaysia, Indonesia, the Philippines, and Thailand. Zebra shark liver is processed for vitamins, while its fins are often used in shark fin soup, the traditional Chinese delicacy. Meanwhile, the species is considered abundant in Australia, where it’s widely distributed and not overfished.

9 Megamouth Shark

Only around 60 confirmed sightings of megamouth sharks have been recorded since the species was first discovered off the coast of Hawaii in 1976. The shark was so bizarre that classifying it required an entirely new genus and family. Since then, megamouth sharks are still the only member of the Megachasma genus. It is the smallest and most primitive of the only three sharks known to feed on plankton. The other two are the basking shark and whale shark.

Megamouth sharks are “vertical migrants,” constantly changing their depth according to the day‑night cycle. They spend daytime in deep waters between 120–160 meters (390–525 ft) below the surface and ascend to mid‑depth waters of 12–25 meters (40–82 ft) during the night.

Due to the megamouth sharks’ elusive nature, very little is known about their population and distribution. Most of the sightings have been registered in areas of the Pacific, Indian, and Atlantic Oceans in countries such as Senegal, Indonesia, Brazil, and the Philippines. Some of the first discoveries were also on the coasts of Japan, Australia, and California.

With a much larger mouth and jaws than the rest of its body, the megamouth is not a great swimmer. To make up for it, the shark has bioluminescent lips which glow in the dark and attract prey in the deep waters where it spends most of its time. According to the Western Australian Museum, megamouth sharks also have flabby muscles, soft bodies, and poorly calcified skeletons that prevent the shark from sinking.

8 Horn Shark

Horn sharks got their name from the high ridges above their eyes and the spines on their dorsal fins. They are also identified by their wide heads, blunt snouts, and dark gray to light brown coloration covered in dark brown or black spots all over. Horn sharks live in subtropical regions of the eastern Pacific, especially along the shores of California, Mexico, and the Gulf of California.

Due to their relatively small size, slow movement, and nocturnal hunting habits, horn sharks are considered to pose little to no threat to humans. But they may still bite if harassed. According to the International Shark Attack File, there is one recorded instance of a horn shark biting a human.

The horn shark population is not currently considered to be under threat. Humans do not regularly consume these sharks and usually discard them when caught as bycatch at the bottom of trawls. However, that may change in the case of significant expansion of gillnet fishery in Mexico. Due to ease of maintenance, horn sharks are also commonly kept in public and private aquariums.

In one bizarre incident, a horn shark was stolen from a Texas aquarium in July 2018. A surveillance camera captured the video of three people stealing the shark by using a stroller and disguising the animal as a baby. Later, an ad selling the shark for $300 was posted online.

Two days later, police found the truck used in the shark heist and arrested one of the three culprits. He was charged with theft, and his bond was set at $10,000. The shark was found alive and well and was returned to the aquarium.

7 Spotted Wobbegong

The spotted wobbegong is one of the 12 species of carpet sharks in the Orectolobidae family. The name “wobbegong” is considered to be interchangeable with “carpet shark.”

This shark gets its name from its flat and broad body which is perfectly adapted to live camouflaged on the seabed. It is distinguished from other wobbegongs by a golden sandy to light green color and an irregular white ring pattern. Spotted wobbegongs also have 6–10 dermal lobes on each side of the head and nasal barbels which are used for sensing their surroundings.

Endemic to the coastline of Australia, spotted wobbegongs can typically be found on algae‑covered rocky reefs, coral reefs, and sandy expanses down to the depths of 110 meters (360 ft). These sharks have often been sighted in waters barely deep enough to cover their bodies.

Spotted wobbegongs spend most of the day lying motionless and become more active at night when they slowly sneak up on bottom‑dwelling prey such as crabs, reef fishes, rock lobsters, and octopuses. They are often observed to return to the same resting site after a night of hunting.

Although sluggish and relatively small compared to other shark species, spotted wobbegongs can be highly aggressive. There have been four confirmed unprovoked spotted wobbegong attacks on humans and another 28 bites from undetermined wobbegong species. There are also several reports of wobbegongs biting people when these animals are stepped on. Once these sharks bite, they are reluctant to let go.

Wobbegongs are frequently caught both as a target species and as bycatch in commercial and recreational fisheries. Between 1990 and 2000, catches declined by more than 60 percent. The tough and attractively patterned skin is often used as decorative leather, while the flesh of spotted wobbegongs is considered excellent for eating.

6 Pyjama Shark

Pyjama sharks can be identified by their unmistakable combination of stripes, prominent but short nasal barbels, and dorsal fins located far back on their body. Quite small for a shark, this species hatches at the length of 14–15 centimeters (5.5–5.9 in) and typically reaches maturity at around 58–76 centimeters (23–30 in).

As a nocturnal species, pyjama sharks tend to be sluggish during the day and can commonly be found resting in caves and crevices down to depths of 100 meters (328 ft). Their prey primarily consists of crustaceans and small fish, such as anchovies.

Due to their small size and feeding habits, pyjama sharks are considered harmless to humans. And humans are not harmful to them, either. These sharks are discarded when taken as bycatch and not used for consumption.

Predators of the pyjama shark include larger shark species. But pyjama sharks are not under any significant threat of extinction and can commonly be found in the southeast Atlantic Ocean and the western Indian Ocean. They are especially common in the Cape Province of South Africa, and there are older, unconfirmed records of the species in the waters of Mauritius and Madagascar.

5 Angular Roughshark

The angular roughshark is named after the rough, toothlike scales, known as “denticles,” that cover its body and two large dorsal fins. This rare shark moves by gliding along the seabed and stops frequently while hovering over muddy or sandy surfaces. With a preference for remaining close to the seabed, angular roughsharks tend to live at depths of 60–660 meters (200‑2,170 ft).

Angular roughsharks are believed to use a suction mechanism to feed on a diet of mollusks, crustaceans, and polychaete worms. Occasional feeding on egg cases of other shark species has also been recorded. Mainly distributed in the eastern Atlantic Ocean, angular roughsharks can be found along nearly the entire western coast of Africa and Europe as well as the Mediterranean Sea.

Due to increased frequency and efficiency of bottom trawling in the Mediterranean and the northeast Atlantic during the past 50 years, angular roughsharks have become extremely rare in many of their endemic habitats and are considered critically endangered in some areas. Although the species is not specifically targeted by fisheries, angular roughsharks are regularly taken as bycatch and used for oil, human consumption, and food for fish farms.

4 Goblin Shark

Goblin sharks are rarely seen by humans as they live up to 1,300 meters (4,265 ft) below the surface. However, some specimens have been spotted around the depths of 40–60 meters (130–200 ft). The majority of goblin sharks ever caught were off the shores of Japan. But the species is believed to be distributed globally, with larger populations concentrated in the waters of Japan, New Zealand, Australia, France, Portugal, South Africa, Suriname, and the US.

Elongated yet flattened snouts and exceptionally sharp, long, fang‑like teeth are some of the goblin sharks’ most distinctive features. Their snouts are also sprinkled with tiny electro‑sensitive receptors that pick up electric fields. Goblin sharks have translucent skin, which leads to visible oxygenated blood within their capillaries and a unique coloration that ranges from pinkish‑gray to bubblegum pink.

Despite its unusual appearance, the goblin shark’s most bizarre feature is its slingshot jaws. The average human mouth opens at roughly 50 degrees, while these sharks can easily manage 111 degrees. The goblin shark’s jaws jut out at a speed of 3.1 meters (10.2 ft) per second when prey comes within its reach. Then the jaws bite down before reopening, just to close again.

Scientists are still uncertain about the reason why goblin sharks open their mouths for a second time after making a kill. But it is believed that this could help with locking down more slippery prey, like squid.

It is also believed that goblin sharks may be found in British waters by 2050. There are 40 shark species living off the UK coast already, and the increase in water temperature from climate change is likely to bring new kinds of sharks from the Mediterranean and the African coast. Experts estimate that another 10 shark species, including goblin sharks, might be found in the UK in the future.

3 Frilled Shark

The frilled shark is one of the most primitive shark species alive today. It is believed to account for several “sea serpent” sightings because of its snakelike appearance that features a long body and tiny fins. The shark is named after the six pairs of gills which meet under its throat and create a frilly collar. But this shark’s most unique feature is its jaws, which contain 300 small, three‑pronged teeth arranged in 25 rows.

Although typically found very deep below the surface, frilled sharks have also been observed at depths between 50–200 meters (160–660 ft) where they feed on squid and a variety of fish, including other sharks. The mouth and body shape of these sharks have led scientists to believe that they can consume prey more than fifty percent of their own body length.

Frilled sharks have a patchy distribution across the globe. Specimens have been recorded in the waters of Scotland, Ireland, Australia, New Zealand, Japan, California, Chile, Namibia, and Norway. There have also been unconfirmed sightings in the Indian Ocean.

Due to a long gestation period and low reproductive output, frilled sharks may be under threat. Small losses of the species could have serious consequences, and individuals are regularly taken as bycatch from deep‑set longlines, gillnets, and trawls. The meat is used as fish meal, eaten by humans, or discarded. So far, very little is known about the frilled shark global population size.

2 Cookiecutter Shark

Despite rarely growing larger than 50 centimeters (20 in), the cigar‑shaped cookiecutter shark is one of the most fearless predators on Earth. It has a brown top and a light underside, which glows to attract other fish.

However, unlike most predators, these sharks do not kill their prey. A cookiecutter shark uses the speed and movement of other fish against them and quickly turns around to take one golf‑ball‑sized bite out of its attacker.

This style of feeding allows the cookiecutter shark to feast on much larger creatures than itself, including seals, whales, and other sharks. The distinctive scars left by the cookiecutter’s specialized teeth scooping out a hemispherical plug of flesh allow scientists to identify what this shark’s diet consists of, and it seems like nothing is off‑limits. There are even reports of this shark leaving crater marks on the sonar domes of nuclear submarines.

Cookiecutter sharks usually spend daytime around 1,000 meters (3,280 ft) below the surface and migrate upward to hunt at night. Human activities are believed to have little impact on this elusive species. It has a patchy distribution, with specimens reported in southern Brazil, Cape Verde, Guinea, Angola, South Africa, Mauritius, New Guinea, New Zealand, Japan, Hawaii, Australia, and the Bahamas.

For many years, cookiecutter sharks were considered harmless to humans because of their small size and habitat. Then came the first documented attack on a human in Hawaii in 2009. Roughly 90 minutes after sunset, one of these sharks took a bite out of a swimmer’s leg. The only two confirmed bites on humans up to that point were found on corpses.

1 Greenland Shark

The Greenland shark is one of the world’s largest shark species, reaching the length of 6.5 meters (21 ft) and the weight of 900 kilograms (2,000 lbs). However, its fins are small in comparison to its size. This shark’s upper jaw has slender, pointy teeth, while the bottom row consists of much larger and smoother teeth.

The coloration of the species has several variations, including gray, violet, brown, and black. Although Greenland sharks are occasionally cooked and consumed by Inuit hunters, the sharks’ skin is toxic to most other animals, including dogs. When fed the raw shark, dogs have been reported to behave drunkenly.

The majority of Greenland sharks are blind because of worm‑like parasites that attach themselves to the sharks’ eyes. Luckily, these sharks live in almost complete darkness and under the ice of freezing cold waters where blindness does not make a lot of difference.

With the help of their excellent sense of smell, Greenland sharks do not struggle with finding food. Carcasses of narwhals and belugas are some of their favorite meals, but they also enjoy seals, sea lions, salmon, halibut, and herring. Sometimes, Greenland sharks participate in cannibalism.

Their life span is even more fascinating. Their eyes contain transparent, metabolically inactive tissue which has new layers added throughout the shark’s life. Analysis of the tissue of 28 Greenland sharks that were captured as bycatch has revealed them to be the longest‑living vertebrates on Earth.

The estimated life span for the oldest specimen was 392 years. But accuracy may vary by 120 years, making the shark a minimum of 272 years old and a maximum of 512 years old.

Greenland sharks are mostly distributed along the coasts of countries such as Canada, Norway, Iceland, Ireland, the UK, and, of course, Greenland. Scientists are trying to discover the reason behind the long lives of Greenland sharks and what may dictate the life expectancy of other species, including humans. These sharks also appear to survive diseases that kill related species much earlier.

A lot remains unknown about these ancient predators.

Dive into the world of cinema’s most unforgettable shark moments as we break down ten unforgettable shark scenes through the eyes of marine scientists. Melissa Marquez and Apryl Boyle bring their expertise to the big screen, separating splashy fiction from cold‑hard fact.

10 Shark Scenes: Science Meets Cinema

10 Jaws (1975)

“I looooove the iconic Jaws music. The build‑up of the music amazing. You’re just sitting there waiting, when’s it going to happen, when’s it going to happen … Aaaawww, there’s the big boy!” enthuses Marquez. The first thing she points out in the shark attack scene above is Bruce’s perfect counter‑camouflage, mirroring the natural coloration of great‑white sharks: darker on the dorsal side and lighter on the ventral side. From above, the dark top blends with the dim water, while the pale belly matches the dappled sunlight from below, giving the predator a stealthy edge when stalking prey.

While sharks occasionally ram cages—especially if bait is drawn too near—the scientist stresses they rarely do it on purpose. Sharks cannot reverse, so once they’re moving and encounter a cage, they have little choice but to push forward. Marquez admits she isn’t overly impressed by the animatronics that created Bruce, yet she concedes the cage design is spot‑on; even in 2020 the basic cage structure remains largely unchanged.

Interestingly, author Peter Benchley, who penned Jaws, later expressed regret over his creation and devoted years to shark conservation in an effort to amend the film’s impact.

9 Baywatch (1989)

“They definitely had a lot of fun filming this! The entire thing is a homage to Jaws,” comments Boyle. “I can’t imagine a lifeguard getting into the water when the boat is right there and can get to them so much faster,” she continues.

First responders are trained to avoid endangering themselves while rescuing others. It’s hard to picture a scenario where a lifeguard would plunge into the water to drag someone away from a shark rather than staying aboard the rescue boat and steering clear of the predator.

“This movie is a giant love letter to Jaws. Over‑the‑top absurd, probably a really fun shoot to do,” Boyle concludes, noting the film’s tongue‑in‑cheek tribute to the classic.

8 Deep Blue Sea (1999)

“If anything is going to be unrealistic about this movie, it’s going to be the scientific results coming out that quickly,” says Marquez.

While the film dramatizes high‑tech underwater labs, real shark laboratories do exist worldwide, primarily for medical research—harvesting blood, hemoglobin, and skin tissue to study immune systems—and for bio‑inspiration, such as designing wetsuits or aircraft wings. Yet the focus here remains on shark attacks, so let’s return to the gore.

In the clip, a scientist loses an arm when a shark leaps from the tank. Although the prop looks realistic, Marquez points out the shark would need far more space to generate enough thrust to launch itself out of the water. In a cramped enclosure, such a powerful burst is highly improbable.

7 The Cradle of Life (2003)

“You probably have a better chance of contracting an infection than you have of attracting a shark,” remarks Marquez, referring to Lara’s self‑inflicted wound used to lure a shark with the scent of her blood.

Sharks are silent hunters—except for dogfish, which emit a bark when out of water. “That sounded more cat‑like than shark‑like,” Marquez laughs. While punching a shark might seem like a deterrent, underwater drag makes it inefficient, and striking the nose could backfire, increasing the risk of a bite. If one must strike, aim for an eye or, better yet, the gills—similar to a knockout to the lungs, it deprives the shark of oxygen and encourages retreat.

“Just as well she’s wearing gloves,” Marquez adds. Sharkskin feels like sandpaper; rubbing against it would cause painful abrasions, effectively a shark‑burn.

6 Finding Nemo (2003)

“Fish are friends, not food… I can’t tell you how many kids have said that to me,” says Boyle.

By portraying a softer, more anthropomorphic shark, Finding Nemo has given children a less terrifying introduction to these predators, fostering modern conservation enthusiasm. Sharks indeed have fish companions—pilot fish and remoras enjoy symbiotic relationships with them.

However, the scene where a drop of blood triggers Bruce into a frenzy is unrealistic. While sharks can detect minute traces of blood in a massive pool, they are selective eaters. “Imagine how easy my research would be if this were true!” Boyle exclaims, underscoring the myth versus reality.

5 Open Water (2003)

“I am literally getting chills.”

Boyle ranks Open Water as the scariest shark film, based on a true tale of two divers abandoned mid‑dive, never to be found. “Being left behind is literally the worst thing that could happen to any diver. That is the most frightening part of this movie,” she says.

The second most terrifying element is the bite itself, which Boyle deems highly realistic and feasible. She has witnessed sharks take a nibble of something, realize it isn’t food, and swim away—making the scene both plausible and chilling.

4 Couples Retreat (2009)

“Why are people always surprised that there are sharks in the ocean? … You’re throwing dead animals into the ocean. What did you think was going to happen?” muses Marquez.

Chumming—using fish blood and entrails to lure sharks—is a technique scientists employ to study these creatures, but it should never be used recreationally, as it invites bites. Marquez questions the film’s identification of the sharks as lemon sharks, yet agrees with the advice to stay calm, avoid panic, and slowly swim away from the chum.

3 The Shallows (2016)

“The shark depicted in this movie is supposed to be a great white. They are very picky eaters. I have witnessed some of them taking a bite of something and spitting it out,” remarks Boyle. “And so, the notion that it would fight so hard for a morsel that is not their usual calorie‑dense food, is rather far‑fetched.”

In the wild, sharks prioritize high‑calorie prey like seals and sea lions, whose blubber offers far more energy than a slender human. The energy expended by the shark in the film—leaping onto rocks and injuring itself—would not be worth the meager payoff of a thin human target.

2 The Meg (2018)

“Megalodon is a very, very, very extinct shark …” laughs Marquez.

Although many liken the meg to a great white, the species vanished millions of years ago. Still, fascination persists. “I promise you there is no shark big enough to snag a massive anchor and tow a boat with dozens of people on board,” Marquez says.

She shares practical safety tips for shark‑infested waters:

1. Always swim with a buddy who can keep an eye out.
2. Avoid splashing like a wounded animal to reduce attention.
3. Remember, the danger often comes from the shark you don’t see.

The largest modern shark, the whale shark, can reach about 40 feet (12 m) but is gentle and unlikely to approach swimmers. Most shark species are shy, conserving energy for richer prey.

1 47 Meters Down: Uncaged (2019)

“While there are some freshwater shark species, they definitely don’t look like this,” says Marquez, referring to the Frankenstein‑like creature in the clip. It doesn’t match any known shark, appears blind, yet possesses five gill slits—an anatomically correct trait.

Although the notion of a cavern teeming with sharks seems far‑fetched, a recent discovery of a shark in an erupted volcano shows nature can surprise. In the film, the sharks circle trapped divers, a real‑world behavior where sharks assess potential prey before deciding to strike. Yet a blind shark circling a cave raises questions about the plausibility.

Overall, the film blends horror with speculative biology, sparking both fear and fascination.

When luck steps in at the very edge of danger, the story that follows is nothing short of extraordinary. In the world of ocean encounters, a handful of individuals have walked away from a shark’s bite by the skin of their teeth—literally. This roundup celebrates ten such daring survivors, each of whom proved that fate can be a surprisingly generous ally. These are the 10 people who narrowly escaped a shark attack, ranging from high‑tech drone warnings to heroic punches that turned a predator’s appetite into a fleeting brush with death.

10 People Who Survived Shark Attacks

1 Year-Old Shark Attack Survivor

In the summer of 2018, thirteen‑year‑old Keane Webre‑Hayes was hunting lobsters off the coast of Leucadia, California, just north of San Diego, when a great white surged up and clamped onto his leg. Three men paddling nearby in a kayak sprang into action, hauling the terrified teen to shore before emergency services could arrive. Keane was airlifted straight to a hospital where surgeons repaired the deep lacerations.

Defying the trauma, the youngster declared he wanted to plunge back into the sea as soon as possible. It took nine months of recovery, but he finally returned to the ocean, this time spearfishing in deep water—proof that courage can outlast even the most terrifying of bites.

2 Punching for Survival

At Bells Beach, Australia, in 2020, Dylan Nacass found himself face‑to‑face with a hungry shark that latched onto his leg while he rode a wave. Reacting in pure instinct, Dylan threw two solid punches at the predator’s head, buying himself precious seconds. A nearby surfer, Matt Sedunary, heard Dylan’s screams, scanned the water, and spotted a glinting dorsal fin.

Realizing a shark attack was underway, Sedunary surged toward Dylan, helping to pull him free and guide him toward safety. Dylan’s quick‑thinking blows and Sedunary’s timely rescue turned what could have been a fatal encounter into a story of resilience and teamwork.

3 Man Fights Off Shark to Save Partner’s Life

On a bright August morning in 2020, environmental scientist Chantelle Doyle was surfing at Shelly Beach, Port Macquarie, New South Wales, when a ten‑foot great white bit deep into her right leg, leaving severe lacerations. Her partner, Mark Rapley, instantly saw the danger and lunged onto her back, delivering a flurry of punches to the shark’s head and eye.

The relentless assault forced the predator to release its grip, and nearby surfers quickly gathered to assist. Doyle’s harrowing experience sparked a renewed commitment from both her and Rapley to shark research and conservation, turning terror into purpose.

4 To-Face with a Great White

Back in December 1963, a twenty‑three‑year‑old Rodney Fox was competing in the South Australian Spearfishing Championship at Aldinga Beach when a massive great white ambushed him. Fox fought back fiercely, even attempting to gouge the shark’s eyes, but the beast snapped his hand shut in its jaws, tearing muscle and bone.

The shark dragged him toward the ocean floor, yet Fox managed to break free before the fatal moment. He emerged with 462 stitches, shattered ribs, a punctured diaphragm, and a ruptured lung. Rather than abandon the sea, Fox devoted the next six decades to championing shark protection, turning his near‑death into a lifelong mission.

5 Overboard for 28 Hours

During a night surf trip to Indonesia in 2013, Brett Archibald slipped overboard after a bout of food‑borne illness and seasickness left him disoriented. He awoke on the boat’s railing, only to realize he was floating alone in the dark, surrounded by churning waves.

For twelve agonizing hours, Brett battled hunger, vomiting, and even a brief encounter with a shark that, perhaps deeming him an unappetizing snack, swam past without striking. After a staggering twenty‑eight hours adrift, an Australian skipper finally sighted him, pulling the exhausted survivor aboard for urgent medical care.

6 Really…in the Middle of a Competition

Three‑time world surfing champion Mick Fanning was riding the finals of the J‑Bay Open in South Africa when a shark burst from the surf, colliding with his board and sending him sprawling into the water. The predator chased him, but Fanning managed to jab the shark’s back, forcing the animal to retreat.

Rescue boats raced to the scene, whisking the stunned champion to safety while his mother watched the drama unfold on live television, her heart pounding as the world saw a sporting legend confront nature’s fiercest hunter head‑on.

7 Fight Off a Shark, Take Selfie.

In 2015, Hawaiian spear‑fisherman Braxton Rocha found himself within a tiger shark’s jaws just 60 yards off the Big Island’s coast. The shark clamped onto his leg, but Braxton’s reflexes kicked in; he punched the predator’s head, coaxing it to release its grip.

After swimming back to shore, he documented his torn leg with selfies and videos, later sharing the harrowing footage on YouTube and Instagram. A friend, Shannon Pasco, rushed him to an ambulance, where a three‑hour surgery sealed the 100 staples that held his wound together.

8 Missed Me by a…Foot

North Carolina’s Ocean Isle Beach became the backdrop for a terrifying 2019 incident when 19‑year‑old surfer Austin Reed felt a shark clamp onto his foot. The bite left a gash that resembled a clean, knife‑like cut across both sides of his leg.

Rushed to New Hanover Regional Medical Center in Wilmington, Reed underwent surgery to repair the damage. The United States logged the most unprovoked attacks in 2020—33 in total—though only three were fatal, underscoring how close many could have come to tragedy.

9 Spearfishing Surprise

Florida‑born boat captain Jonathan Hernandez was spearfishing near Abaco Island, Bahamas, in 2019 when a shark lunged at his left calf, delivering a bite that felt like a vehicle had run him over. His friends acted swiftly, applying a tourniquet within ninety seconds, staunching the bleeding.

Hernandez believes the attack stemmed from local shark‑feeding operations that conditioned the predators to associate humans with food. His narrow escape occurred just days before a college student in the same region was fatally attacked, highlighting the perils of feeding wild sharks.

10 Saved by a Drone

Australian pro surfer Matt Wilkinson was gliding near Sharpes Beach in 2020 when an unseen shark trailed him beneath the surface. He heard a distant splash but kept riding, oblivious to the danger. Meanwhile, drone pilot Beau Monks, scanning the water from the air, spotted the predator and instantly broadcast an alert.

Monks instructed Matt to head for shore, and the surfer complied, only later realizing the shark had been mere inches from his leg. The drone’s buzzing may have distracted the shark just enough to prevent a lethal bite. That year, Australia accounted for 18 of the world’s 57 unprovoked attacks, the second‑highest national total.

Since 2009, ABC’s Shark Tank has handed hopeful entrepreneurs a chance to win the venture‑capital backing of their dreams. The “sharks,” who have largely stayed the same throughout the series, have truly seen it all – and that includes the top 10 dumbest products ever pitched on the show.

Why These Are the Top 10 Dumbest Shark Tank Pitch Failures

10 Morninghead (Not as Exciting as It Sounds)

First, let’s define what we mean by a “scam” in this context: a completely ordinary idea, wrapped in slick marketing, that promises big bucks from unsuspecting buyers. In other words, a brain‑dead concept that somehow looks shiny enough to sell.

Enter Morninghead – a product that claims to rescue you from the dreaded bed‑head without a shower. Instead of dry shampoo, a brush, or any real hair‑care magic, the inventor offers a simple shower cap that you fill with water, pop on your head, and give a quick shake. The result? Your hair is merely damp, not clean – a soggy, half‑done fix for those “I’m late but I need my hair presentable” moments.

The sharks burst out laughing, the pitch fell flat, and the entrepreneur walked away empty‑handed. If only the concept had been as promising as its name sounds, perhaps the outcome would’ve been different.

9 Sticky Note Holder

Organizational tools will always have a niche market, but the digital age has dramatically reduced the need for sticky notes. The product itself isn’t inherently stupid; the problem lies in the pitch’s lack of relevance and the product’s overall usefulness.

Mary Ellen Simonsen unveiled a “sticky pad” that clings to the side of a computer monitor. Her demo involved sticking a cardboard‑like pad onto a laptop screen – a less‑than‑convincing showcase. She asked for a $1 million investment, pricing each holder at $9.50, and claimed the numbers came from “surveys.”

When pressed about patents, she admitted none existed. Daymond John summed it up succinctly: no patent, no sales, a useless idea – he was out.

8 Licki Brush

This one walks the line between absurd and oddly clever. PDX Pet Design pitched a silicone, spiky‑tongue brush meant to let owners “bond” with their cats by licking them, mimicking how mother cats groom their kittens.

Co‑founder Tara began by suggesting cats see humans as big cats, not a separate species, and framed the product as a way to join that intimate ritual. Right away, the pitch raised eyebrows.

Jason, her husband, brought a live cat onto the stage while Tara demonstrated the tongue brush, even putting it in her own mouth before licking the feline. The sharks’ reactions were a mix of disbelief and amusement.Despite the obvious red flags, the product still manages to stay on the market today, proving that even the most bizarre ideas can find a buyer.

7 No Fly Cone

Bruce, a barn‑working entrepreneur, introduced the No Fly Cone – a cone‑shaped trap designed to sit over a dog‑poop scooper, theoretically keeping flies away from waste. To boost credibility, he enlisted a “spokesperson” named Seth MacFarlane, who claimed to have horseback‑riding lessons with Bruce.

The concept hinges on having a constant supply of dog waste, which makes it a niche product at best. For most viewers, the idea feels unnecessary, though a barn‑owner with a fly problem might find a use for it.

6 Fish FrenZ

Australian Shark Tank star Lourens Badenhorst presented a bait‑release container that drifts with the current, aiming to give anglers an edge. He tried to market it specifically to women, claiming they needed a “competitive edge” in fishing.

The sharks repeatedly asked whether the product was exclusive to female anglers, and Lourens kept insisting it was for women, while also saying men already know everything about fishing. The gender‑focused angle left everyone confused.

The product never secured a deal, and Lourens left without any backing, reminding us that a solid invention can be derailed by a misguided marketing spin.

5 UroClub

Imagine being on the golf course, desperate for a bathroom break, with no trees in sight. The UroClub attempts to solve that dilemma by disguising a portable pee receptacle as a seven‑iron golf club.

The design includes a privacy towel that folds over the “club” when in use. While the concept shows a genuine attempt to address a real problem, the practicality is questionable – you can’t swing a club while concealed, and it’s not a gender‑neutral solution.

Because of these limitations, the UroClub lands firmly on the list of questionable Shark Tank inventions.

4 BareEASE

Dr. Edna Ma, an anesthesiologist, introduced BareEASE – a numbing kit for bikini‑waxing. The product consists of underwear infused with numbing cream, meant to be worn about an hour before a waxing or laser session.

The sharks expressed mixed feelings, ultimately rejecting the pitch due to limited sales data and a crowded market. While the concept aims to ease pain, the idea of wearing numbing underwear feels uncomfortable to many.

Personally, the thought of numbing one’s private area with underwear is unappealing, and it’s not something most people would voluntarily try.

3 I Want to Draw a Cat For You

Steve’s quirky venture lets customers send in specifications for a custom‑drawn cat, which he then sketches and returns. Though the premise sounds frivolous, the business has actually turned a profit, thanks in part to a Black Friday partnership with Groupon.

Mark Cuban invested $25,000 for a 33 % stake, promising to help produce a cat drawing for every 1,000 orders. The model may resemble an NFT‑style “cat art” service, but it’s proven to be financially viable.

In short, the idea is undeniably dumb, yet the execution is surprisingly clever and profitable.

2 Kook’n Kap

Juli Deveau and Ozma Khan tackled the annoyance of hair picking up cooking odors with the Kook’n Kap – a simple, cap‑like cover you slip over your hair while you’re in the kitchen, preventing smells from clinging.

They marketed it as a modern twist on the classic chef’s hat. While the concept is straightforward, the pitch felt like a waste of brainpower, and the product itself offers limited value for most home cooks.

Overall, it’s another example of an idea that solves a very niche problem without broad appeal.

1 Pet Paint

Pet Paint is exactly what it sounds like: a colored hairspray designed for pets, complete with stencils for creative designs. The product promises a quick way to give your dog or cat a splash of color.

However, every time you spray your pet, you’ll end up with a messy wash‑down session. The novelty quickly wears off when you realize you’ve just added another chore to your routine.

In a world with far more pressing problems, adding paint to your pet’s fur is certainly not a priority.

Shark Week is an opportunity for shark lovers to learn more about incredible creatures via the power of science and storytelling. As one of the most popular marine documentary programs, Shark Week manages to pull in millions of fans who tune in from all over the world whenever it airs.

But over the years, Shark Week has come under fire for its programming choices, with many finding faults with its premium content.

Our list dives into the top ten shark week conspiracy theories that cause heated debates among scientists and viewers alike. For some, the theories are plausible, but to others, they are just a marketing flourish for various actors looking to cash in from the publicity that shark fins create.

10 Fake Shark Stories

In 2014, Shark Week aired Shark of Darkness: Wrath of Submarine, featuring a spooky tale about a shark called Submarine. Taking viewers to the wild shores of South Africa, the documentary narrated how a 30-foot (9-meter) white shark terrorized passengers after their boat sunk. While the story was gripping, it only had one mistake—but it was a big one. The story was based on a fictional occurrence featuring a mythical shark.

This was not the first time Shark Week featured a fake-u-mentary, but according to audiences, it was the most insensitive depiction to date. The events in the production were based on Hout Bay, a location where a boat ferrying capsized, leading to the death of two passengers. Trying to create a fictional story was one thing for viewers, but passing it off as an actual historical event was even more infuriating.

As it turns out, the story about Submarine was a fictionalized legend from the 1970s when journalists decided to play a prank on the public. Over the years, the shark was supposedly sighted across the ocean despite not existing in reality.

9 Rogue Sharks

National Geographic did a segment on rogue sharks and what could trigger a shark to attack. In 2018 in Australia, at the Whitsundays Islands, ocean goers were being attacked in formerly safe waters.

While rogue sharks are not common, bull sharks can be some of the most deadly when involved in a shark attack.

To study the sharks, scientists consider the human impact on the Whitsundays waters. With so much water activity, like boating, fishing, paddle boarding, etc., people were disposing of food waste by tossing scraps overboard and even baiting the water. Both practices are not allowed, but sharks soon learned this area was like a fast food drive-thru.

So sharks understood that when a person threw something from the boat, it more than likely meant dinner. But that also meant that when a swimmer jumped off a boat or fell off a paddleboard, they were being bitten immediately.

Most shark bites and attacks are cases of mistaken identity. This can be due to murky water conditions, a person’s resemblance to a mammal such as a sea lion, or their resemblance to food waste. Despite what Hollywood shows as vindictive or rogue sharks, attacks are rare.

8 Victims Stalked for Days

What would you do if you found yourself stranded in shark-infested waters? This question is explored in Shark Week’s 2019 show, Capsized: Blood in the Water. Like most Shark Week shows, the inspiration for the show was drawn from real-life events. But according to some circles, Shark Week is too obsessed with the sensationalized gritty aspects of the creatures while abandoning the science.

Blood in the Water focuses on the events surrounding a 1982 incident where a yacht crew found itself in the water after their boat capsized in a storm. A passenger who had sustained injuries was bleeding, and the blood drew the attention of tiger sharks. The predatory tiger sharks roamed the ship for five days, taking out one victim after another.

While the gritty events are entertaining for Shark Week audiences, not everyone is impressed with the production’s direction. Dr. Stephen Kaijura, a shark expert at Florida Atlantic University, told NBC News that it was disappointing that Shark Week focused on sensational aspects alone. He felt that the animals have diversity and carry a rich history of revolutionary interest. While these elements can offer more scientific information and knowledge, Shark Week focuses on catchy titles and themes.

For scientists and most viewers, Shark Week might only focus on sensational storytelling, ignoring the reality that it started as a scientific and educational program.

7 Shark Spies

In the movies, everyone can be a spy. Kids, senior adults, and even pets can be trained to complete various tasks in the service of a particular intelligence service. If you think you’ve seen everything, brace yourself for this conspiracy: Spy agencies can train sharks to “attack” humans.

In a controversial theory that made international headlines, bloody shark attacks in Egypt were blamed on the Israeli spy agency. The 2010 Sharm El Sheikh shark attacks, which led to the injury of Russian and Ukrainian tourists and the death of a German woman, were unprecedented. But after the attack, the narrative shifted, with some theorists blaming the shark attacks on the Mossad agency.

Conspiracy theorists claimed that Mossad used GPS tracking devices to guide sharks into Egyptian waters. With the historical tension between Egypt and Israel, the conspiracy theory had enough fodder to fuel it.

Before the attack, the two species of sharks that were implicated (the oceanic whitetip and mako shark) were commonly sighted, but attacks on humans were rare. In response to the attacks, the Egyptians declared an open season on sharks found in the nearby waters. By the end of the season, a mako and an oceanic whitetip were killed!

6 The Frilled Shark

Let’s go back about 80 million years when the frilled shark roamed the seas. With a long, thin body, these sharks swam around deep in the ocean; many believe that the shark survived and can still be found today at nearly half its original size. Yet, I would still give this shark a wide berth.

At its full size, the frilled shark has 25 rows of teeth, for a total of nearly 300 teeth. Additionally, the shark has six-gill slits on either side of its body to create a sucking action when attacking prey.

The Discovery Channel aired an episode titled The Frilled Shark during Shark Week in July 2021. They had captured a small frilled shark and were interested in studying the ancient shark. While the shark was fairly docile when threatened, it did try to attack.

Our encounters with such creatures are unlikely due to the depth at which they live. Frilled sharks enjoy swimming at nearly 4,921 feet (1,500 meters). And at those depths, you are likely to run into the famous Kraken. I think I’ll stay near the surface to avoid both creatures.

5 Sharks Avoid the Bermuda Triangle

The Bermuda Triangle, also famously known as the Devil’s Triangle, is an urban legend of the Atlantic Ocean. Off the coast of Miami, Puerto Rico, and Bermuda, the triangle has been blamed for the disappearance of hundreds of ships, suggesting the role of some out-of-world force. Now, some conspiracy theorists believe that sharks stay away from this black spot as a confirmation that there’s some sinister force at play.

The theory started with a TikTok user known as the Friendly Neighborhood Dogdude, who claimed that sharks avoid the area. Claiming that he used a shark tracking app, the social media theorist argued that the swim patterns reveal that the triangle exists and intelligent sharks avoid it. For many TikTok users, the evidence was proof that there was something in the water, proving the Bermuda Triangle theory valid.

While the theory appears legitimate, scientists explain the swimming patterns with a simple fact: Sharks swim into areas where there’s food. Sharks might not be going into the triangle because they don’t see any reason to do so. Also, sharks are known to migrate all the time, so how long did our TikTok sleuth track the sharks? Marine research usually takes months or years to conclude the facts, not a few days before major conclusions are made.

4 Are Dolphins Superior to Sharks?

Many of us have heard this theory, and some parts are true! Sharks tend to avoid dolphins when possible. For one, dolphins have a mix of flexible and rigid bodies, allowing them to evade or attack more easily. In comparison, sharks are pretty rigid, even if they attack with strength.

Let’s not forget a dolphin’s nose. Their nose can act as a battering ram in the case of an attack. Some dolphins even place themselves under a shark and swim quickly upward, plunging their hard nose into the soft belly of a shark. Talk about a sucker punch!

While this may not qualify as a Shark Week conspiracy, maybe dolphins need their own week on TV too.

3 Megalodon: The Monster Shark Lives?

Shark Week is scientific, informative, and aired on the reputable Discovery Channel. But, when Shark Week aired Megalodon: The Monster Shark Lives in 2013, it found itself in an uncomfortable position. The show had passed off a fictional production for a documentary, claiming that the now extinct megalodon had somehow made a comeback. In a world where fake news can sink even the most reputable organizations, Shark Week struggled to stay afloat.

In the 2013 episode, Shark Week brought the megalodon back to life, claiming that the marine megafauna was alive and terrorizing the open seas. The film featured multiple videos, photos, and firsthand encounters of scientists and witnesses that fabricated evidence of the shark’s existence. As an educational show, many felt that Shark Week had failed miserably and the public outrage that followed was proof.

To counter the negative reviews, Shark Week was forced to add disclaimers that the program was fictional. Yet, despite all the backlash from fans, Shark Week 2013 had great TV ratings. To date, it’s considered one of the most watched Shark Week shows, attracting close to five million viewers.

2 Have We Seen It All?

As our list winds down, you may be asking how, after 34 years, does Shark Week still have new content to release? Shark Week started in 1988 and shows no signs of extinction. Well, you could argue scientists learn something new every day. Or you could argue that it is all about the network’s money-making practices.

Either way, these YouTubers said it best, “We Saw Sharks Doing Sharky Things.”

1 “Baby Shark” Nation

The most popular shark of all is… “Baby Shark!” We had to throw in some humor after so much real-life shark stress. But did you know that even “Baby Shark”” has a conspiracy behind such a catchy tune?

The conspiracy follows that the song was created to amass a huge following. Families and kids across the world sing loyally along to the song. But with various versions, kids can be swayed to take action. Good and bad. I’m unsure how much ground this conspiracy holds, but I’ll let you decide.

Sharks are the most maligned creatures on earth. For most of human history, no one cared about these animals until swimming began to grow in popularity. The odd shark attack put them on the radar, and then the movie Jaws sealed their fate. They were slaughtered by the thousands afterward. Nowadays up to 100 million are killed every year. And it’s a damn shame because sharks are amazing in ways that most people never realize.

10. Sharks Attack More During a Full Moon

According to PETA, a cork from a champagne bottle is more likely to kill you than a shark. Whether or not that’s entirely true, it is a fact that shark attacks are relatively rare, and far rarer than most people think. Only 10 people died from unprovoked shark attacks in 2020. That said, if you want to maximize your odds of not being in the net group of 10, choose the time you head into the ocean wisely.

It turns out that sharks are the werewolves of the sea. Attacks tend to happen more often during a full moon than other times of the month. The fuller the moon, the more the attacks. And that makes it seem like perhaps the moonlight is allowing sharks to see better and therefore attack more, except that the attacks generally happen during the daytime, it’s just that they coincide with these lunar phases. 

We know that the moon has an obvious effect on the oceans with how the tides work, but clearly it’s angering up some sharks as well.

9. Some Sharks Glow in the Dark

Is a shark more or less intimidating if you can see it coming? There’s obviously something terrifying about something jumping out at you from nowhere, but what if you can see it approaching and just have no way to defend yourself? And with that in mind, would you be more or less scared of a shark that glows in the dark?

Bioluminescence is still something of a novelty to humans because, in the space we occupy, few animals are capable of glowing. In the sea, there are upwards of 1,500 species of fish that have the ability to generate light. These are generally deepwater fish, and they’re usually not sharks. But some of them are. In particular, three species discovered off the coast of New Zealand. One of them, the kitefin shark, grows to nearly six feet in length.

8. Several Shark Species Can Walk on Land

Whether their reputation is deserved or not, one thing most people could take solace in when it came to sharks was that they’d leave you alone if you left them alone. They live in the sea; we live on land. We never have to cross paths if we don’t want to. And then you find out that some sharks can walk on land. 

Science has identified a handful of fish species that can actually walk on land. In 2020, four new species of walking shark were identified. And if you read about them, the story details how they can use their pectoral fins to walk across the sea floor and hunt prey that lives under rocks and in coral. And that seems cool because they’re walking but not “land” walking, right? 

Of course, the epaulette shark is able to walk on land outside of the water, a feature that likely evolved to help it survive if it gets caught in shallows or in a pool when the tide goes out. They can stay out of the water for up to an hour.

7. Sharks Smell in Stereo

No doubt you have heard that a shark is able to sense electrical signals in the water, which is how it hunts. And if you think that’s to make up for poor eyesight, think again. Sharks have vision 10 times greater than humans. And if that wasn’t enough, their sense of smell is far more advanced than what a human has as well.

Sharks don’t just smell prey in the water, they smell it in stereo. When a shark is swimming and there’s injured prey in the water, the smell will hit one nostril before another. The shark will navigate by the timing of the smell that reaches it, so it will turn towards whichever nostril smelled the smell first. As they swim, moving their head through the smell, they pick which nostril is getting the most smell to direct their movements.

In highly concentrated areas of smell, say a pool of blood, they need to be able to distinguish which nostril is getting the highest concentration of smell and adjust their tack based on that. They can make these adjustments to their direction in mere seconds. 

6. Venomous Sharks live in the Thames River

There are a lot of dangerous animals in the world, and they can be dangerous for different reasons. Things like bees and hornets attack in large groups. A cheetah is fast. A rattlesnake is venomous. And a shark has deadly jaws and speed in the water. But at least that’s all. Except for a couple of species of sharks that are actually venomous, too.

Turns out that being a shark just isn’t intimidating enough for a handful of species, including one that’s been found in the Thames River in England.  Though the Thames was essentially a polluted trickle of death for many years, it’s been making a steady comeback lately and part of that has included signs of sharks known as spurdogs in the water. Spurdogs are just under two feet in length and have spines in front of their dorsal fins that can envenomate prey. 

5. Cookie Cutter Sharks Disabled Nuclear Subs

Jaws made us afraid of Great White sharks but the real terror of the deep are cookiecutter sharks. They may only be 20 inches long, but these little beasts have a real horror movie side to them, which is basically their mouths. They get their name because that mouth allows them to bite nearly perfect circles out of their prey. And then some.

Turns out the sharks like to bite almost everything, including nuclear subs. Their tiny size and unique mouths meant that, back when nuclear subs were first taking to the water, any exposed non-metal parts were perfect prey for the sharks. They’d bite hoses and cables and whatever else they could reach. Their attacks on rubber sonar domes blinded subs and forced them to return to dock for repairs. 

The subs were later designed with some stronger materials and the tiny sharks’ reign of terror was over, at least insofar as it related to nuclear weapons.

4. Sharks Were Discovered in an Active Underwater Volcano

The microscopic tardigrade is one of the most indestructible creatures in the world. They can survive mountaintops and the depths of the ocean, they can survive outer space and temperatures that range from -328 degrees to 300 degrees Fahrenheit. It seems like no environment is too extreme. And, as it happens, there are some sharks that have taken a page from the tardigrade’s book.

Near the Solomon Islands there’s an underwater volcano called Kavachi. It’s an active volcano, and it erupts frequently, spewing ash and lava and chemicals into the water. In 2015, when researchers went to investigate, it was not erupting at that time, but the water was still very hot and acidic. They sent down a camera and saw two species of shark living right in the caldera of the volcano. 

Sharks are known to be able to endure deep water, so the water around the volcano is just another extreme. It’s believed that their ability to sense electromagnetic signals may help them survive by warning them before the volcano actually erupts so they can leave the area.

3. Sharks Like Jazz

There is an abundance of research that shows animals like music. Classical music causes cows to produce more milk. Elephants seem to like classical music as well. And sharks? Well, they respond to jazz.

Based on research that involved using food as a reward, researchers determined that sharks were more attracted to the sound of jazz music than something like classical. When they played jazz music, the sharks would swim towards it to get their food reward. When combined with classical the sharks got confused but cut them a break, they’re just fish. 

The research is a nice complement to the idea that sharks tend to be attracted to certain sounds in water, in particular boat engines. People on boats chum the waters, in particular when they want to swim with sharks, so it shows sharks can learn to go towards certain sounds that might otherwise seem like they should offer nothing or even scare animals away.

2. Bull Sharks Can Live in Freshwater

Although Great White sharks get a lot of press because of movies like Jaws and the fact that they’re just kind of huge, they are not considered the most dangerous shark in the sea. That honor goes to bull sharks. Bull sharks are highly aggressive and are not afraid to protect their territory. Keep in mind there are not that many shark attacks from any species at all, but bull sharks are still one of the more aggressive species in the water. And the fact they’re not confined to saltwater makes them a little more intimidating.

Most sharks need to regulate the levels of salt in their body and that requires them to live in saltwater all the time. A great white shark in freshwater will die fairly quickly as its cells breakdown due to a lack of salt when their body essentially becomes diluted with freshwater. A bull shark, however, has adapted the ability to recycle salt in its own body through its kidneys and some tail glands that retain salt.

Bull sharks typically have their young in fresh or brackish water, which helps protect them from predators. Though they do head out to sea eventually, they are able to stay and thrive in freshwater. 

1. Sharks Can Pushed Their Insides Right Out

Sharks are known as voracious eaters.A great white can sustain itself for around two weeks on 66 pounds of food. A whale shark will consume 46 pounds of plankton per day. Suffice it to say, sharks can eat. And not everything they consume is even food. Some have been caught with things as bizarre as wine bottles, drums, and even a cannonball in their stomachs. 

Given how much goes into a shark, it seems reasonable that there has to be a way for it to get back out again. And there is, even if it’s not the way you’d think. Sharks have the ability to throw up in the most over the top way possible, by forcing their entire stomachs back out of their mouths. 

The act is most often seen when sharks are under stress, from things like being caught by fishermen or being beached, for instance. 

It’s believed that sharks do this not just out of stress, but also to essentially rinse out their stomachs. If they have a lot of foreign material or dangerous materials inside, they can dump it, rinse it in seawater, and suck it right back in. It takes only a moment for a shark to push its stomach out and then swallow it again, and they seem to be no worse for it once it’s done.
