Every culture has its fair share of mythological beings, but when it comes to wicked creatures, Native American folklore offers a truly chilling roster. From shadowy spirits that lure travelers to monstrous hybrids that roam the tundra, these legends have terrified listeners for generations.

Wicked Creatures of Native American Folklore

10 Bookwus

Also known as “Bakwas,” “Bokwus,” or “Bukwis,” the Bookwus is known as the “Wildman of the Woods” among the Kwaqiutl tribe. The Bookwus is a spiritual being associated with the souls of those who have drowned, and it lives around ocean shores at the edges of forests. The main danger of encountering a Bookwus is their desire to lure humans into their invisible home. They will share food such as salmon and berries that will prove too good to resist. In truth, the food is cursed, and those who eat it become a Bookwus themselves. They are shy of humans in general, and their favorite food is cockles.

Masks of the Bookwus are often crafted with great care and feature large eyebrows, round eyes, and a pointed nose. There is a dance of the Bookwus where performers wear the masks and overalls with cedar branches pinned to them and proceed to act out the Bookwus’s shyness of humans and his search for cockles to eat.

9 The Rolling Head

The Midwestern tribes feared a head that rolled around by itself. It had long hair and an intent to hunt down and devour anyone that it caught. The origin story of the rolling head has several different versions.

The first story claims that the rolling head began as a person who licked one of their wounds to help it heal. The person decided they enjoyed the taste of human blood and devoured the rest of their own body until only the head was left. Now, they roll around looking for the next victim to satisfy their taste for blood.

Another version states that the rolling head started from a murder performed by a loved one. Some stories tell of a husband who murdered his wife and force‑fed the flesh to their children. Others say the husband fed the wife her own flesh before finally killing her off. In either case, the person who was murdered rose again as the rolling head to seek revenge on their murderer. Once vengeance was attained, the head continued to terrorize people until it was put down.

8 Baykok

One creepy tale among the Chippewa people is that of the Baykok—giant skeletons with translucent skin and black eyes that turn red when they stalk prey. The Baykok are believed to have come into existence after a hunter was left to die in the cold after being trapped. The hunter was angry that his fellow tribesmen had failed to help him from his predicament, so he held onto his life force and transformed into the hulking skeleton which the Chippewa people have come to know.

The way to detect a Baykok’s approach is to listen for his taught skin stretching and his bones popping. He prefers to attack at night by putting people to sleep with invisible, poisoned arrows. Once the victim is unconscious, the Baykok slices open the victim with a knife, cuts out the liver, and replaces it with a stone. The Baykok gets a free meal while the victim, unable to remember the attack, slowly dies from the lack of their liver.

7 Unhcegila

Also known as Unk Cekula or Unktehi, this creature is described by the Lakota tribe as a large dragon. Stories of the Unhcegila began to appear after neighboring Lakota tribes began to report numerous rumors of a shadow that appeared from the sea and nestled within the mountains of the Black Hills.

At first, it was described as having no visible form, and its entire body was shrouded in smoke. Over time, the Unhcegila revealed itself to have a long, scaled body that proved impenetrable to spears and arrows. Despite this, the Unhcegila was defeated. How it met its fate has multiple stories attached to it.

One tale claims that the Unhcegila once coexisted with the tribesmen. Soon, however, the dragon’s offspring developed a taste for human meat, and the tribesmen fought back. Another variant says that a warrior was instructed by a weasel spirit to be swallowed by the creature. The warrior cut his way out from the inside of the beast and killed the Unhcegila. A third origin claims that two children had a bow and some magic. They managed to strike the Unhcegila’s only weak spot, killing the being. In any case, it’s probably a good thing that it’s dead.

6 Apotamkin

In modern times, the Apotamkin got exposure after the movie Twilight gave reference to the real‑world myth about the case of “The Cold One.” The closest thing to what the movie might be referencing is the Native American Apotamkin, which people believed were vampires. The truth is, the actual case for what an Apotamkin is is up in the air.

One source states that the Apotamkin are indeed vampires that come with the full range of powers you’d expect (empowered abilities, super strength, and the desire to gain sustenance from human blood). Unlike the modern vampire, Apotamkin could also feed off animals and had more of a zombie corpse aesthetic to them, hence the name “Cold One.”

Another tale claims that the Apotamkin was not a vampire at all. It was a sea serpent that dwelt along the Passamaquoddy Bay. When people became careless and walked too close to the water’s edge, the Apotamkin would snatch them and drag them into the water. Some say the Apotamkin was a woman who had turned into a serpent with long, red hair.

Both origins state that the Apotamkin was used mainly as a story to warn children of the dangers of acting incautious. Vampire or not, the Apotamkin probably made a few children stay safe over the course of its mythical history.

5 Kee‑Wakw

Also known as the “chenoo,” “kiwakwa,” or “giwakwa,” the kee‑wakw was a giant in the Wabanaki tribe’s mythology.

Meeting face‑to‑face with a kee‑wakw probably wasn’t the best idea. If you angered one, the beast rapidly increased in size until it was taller than the trees. These creatures had gigantic fangs and a taste for human flesh. The only chance of surviving was to hope that the kee‑wakw wasn’t hungry . . . and they were always hungry.

The origins of what made the kee‑wakw varies. Some legends say that a powerful shaman had the magic to rise from the grave as the creature itself. Other stories tell of someone possessed by an evil spirit or committing a serious crime (such as allowing a tribesman to starve) that caused their heart to turn to ice and them into a kee‑wakw. Some legends claimed it wasn’t a transformed human, but a monster by birth. The ice chunks within them were the source of their power. To defeat the kee‑wakw, you had to make it vomit up the ice or dissolve the creature with salt. Sometimes, doing so would turn the kee‑wakw back into the human they once were.

4 Puckwudgie

Originating from Wampanoag folklore, the Puckwudgie was a 60‑ to 90‑centimeter‑tall (2–3 ft) demon that haunted the woodlands. They looked fairly human except for their giant nose, fingers, and ears. Rumors of the demon’s abilities were quite varied. A few of these included the ability to disappear at will, use magic, poison arrows, create fire, or to transform into a walking porcupine.

The story of how the Puckwudgie came to be goes back to a story of the giant called Maushop, another key element in Wampanoag folklore. The Puckwudgie became jealous of the praise that the tribesmen gave Maushop, so they decided to help out the tribe as well. Their well‑intended plans didn’t turn out so good, so they decided to become a malevolent force of evil instead. Maushop was called upon to scoop up the Puckwudgies and scatter them across the land. Many died, but some survived the drop.

Once Maushop had left the tribe for a while, the Puckwudgies returned and burned the villages and kidnapped the children in revenge. Maushop sent his five sons after them, who were all killed. An enraged Maushop took matters into his own hands, but he, too, fell to the hands of the gremlins. Ever since, the land has been plagued by these malevolent imps seeking revenge on the Wampanoag people.

3 Basket Ogress

Also known as the Basket Woman, this legend doesn’t originate from just one tribe. Most of the tribes along the Northwest coast know of the giant Basket Ogress, and she acts more of a Native American boogeyman than other creatures.

The Basket Ogress’s biography sounds like it came from a fairy tale. She enjoys kidnapping people (naughty children in particular) and placing them in her giant basket. When she’s collected enough for a meal, she takes them back into her lair and eats them.

There’s one crucial flaw to the Basket Ogress, and it is usually her downfall in the tales. While she is strong, she is also dim‑witted and easy to trick. One story has several captured children watching as the ogress prepares some hot rocks to cook them on. They manage to convince her to do a song and dance before cooking them. While distracted with her dance routine, the children work together to push her into the hot rocks.

2 Akhlut

The tale of the Akhlut comes from the Inuit and tells of a man who became so obsessed with the sea that he wanted to live in it. One day, upon returning to his village, it appeared that his desire to live underwater had changed him. The rest of the villagers didn’t recognize him anymore and exiled him, so he wandered the lands seeking revenge.

While traveling, he came across a pack of wolves. The nature of the wolves matched his hunger for revenge, and he became a wolf himself. He realized he could transform into the animal that matched his desire. With his newfound ability, he leaped into the ocean and became an orca. He swam around the seas until his desire to ravage humans overtook him. He jumped onto the shore as a wolf and hunted the tribesmen.

It is said that if you’re in the realm of the Inuits and come across wolf tracks that lead directly to the sea, there’s a good chance you’ve come across the prowling grounds of the Akhlut.

1 Adlet

Another Inuit‑based creature is the Adlet, and it’s one of the more twisted stories. The Adlet themselves are the resultant offspring between a human Inuit woman and a red dog. There were 10 children in total, all of a mixture of human and dog. Some stories claimed that the Adlet had the lower half of a dog and the upper half of a human. Others said they had the body of a dog with the intelligence of a human.

After the children were born, the family was exiled to an island. Every day, one of the children swam back to the mainland and received boots filled with meat from the woman’s father to help feed the family. One day, the father loaded the boots with rocks instead of meat and drowned the dog on his voyage back. The woman was outraged and unleashed her children to the mainland to kill her father and anyone that stood in their way.

A simpler version says that the woman didn’t travel anywhere. She sent five of her offspring overseas to ravage other nations. The other half of her children stayed home, and together, they populated the land with deadly Adlets, who drank the blood of recently killed tribesmen.

Bizarre and sometimes dangerous marine worms represent genuine monstrosities in animal form. These creatures can display the worst possible combination of being slimy and “toothy”. Prepare for a science‑fiction‑turned‑reality journey into the weird and wild world of water worms that slither and chomp their way through ocean life. 10 wicked worrisome creatures await your curiosity.

10 Wicked Worrisome Highlights

10 The Bootlace Worm

Too long to believe

Just how long can a worm get? Maybe try asking a Bootlace Worm next time you tie your laces at the beach. Reaching a crazy length of up to 180 feet, the Bootlace worm Lineus longissimus is not merely the longest worm on the planet. It is the world’s longest animal, period. Being the longest is not enough horror for this record‑breaker. The worm outdoes itself by being superbly poisonous to boot. The worm creates a potent toxin that is contained within the slimy mucous secreted by the worm. This hazardous chemical soup was found to be a peptide‑based compound in the course of investigation by Professor Ulf Göransson and colleagues at Uppsala University in Sweden. The primary toxin in the mucus could immobilize invertebrates such as crustaceans and insects. Interestingly, deadly peptides are found in cone shells from the tropics, but the discovery of bootlace worm toxicity represents a cold‑water example. The bootlace worm thrives in chilly waters off European coasts. As a poisonous rather than venomous animal, the bootlace worm is an interesting case given the worm’s use of poisonous mucus to hunt. Typically, a poisonous animal uses a toxin as a defense against being eaten, whereas a hunter would inject venom.

9 Osedax Worms

Oceanic Undertakers

Ocean‑going killers of cetaceans such as large sharks and Orcas might have some little accomplices in the form of worms that take care of the evidence. What happens to whale bones when they sink to the bottom of the sea? Why might it be hard to find many whale skeletons? They get eaten. Little marine worms called Osedax crave bone minerals and actually feed on the bones of whales. Nature lets nearly nothing go to waste and bone‑eating seems to be working well for these creatures.

The so‑called “Zombie worms” are a fairly new discovery, first observed in 2002 in the wild thanks to advances in deep‑sea exploration before being scientifically described in the lab in 2004. The worms were discovered at a depth of 10,000 feet feeding in a grey whale skeleton. Crazier yet, these creatures lack a stomach or a mouth. Osadex worms just secrete acid that melts bone, releasing meat‑like nutrients for the worms to take up through the work of symbiotic bacteria that proceed to break down the actual nutrients. Only females do the acid drilling, while males live inside the females as microscopic organisms. Would the worms eat a dead human? Pretty likely, since they have fed on cow bones at sea…

8 Piling Worm

Mating En Masse

When the lunar signals are right, huge marine worms common in the Pacific Northwest called Giant piling worms, grow up to a foot‑long swarm to the surface and mate. The majority of the time, the creatures stay hidden in the sand, collecting food with their pincer‑like jaws. Imagine swimming at night and being surrounded by foot‑long marine worms. No thanks.

The marine pile worm species was identified as Nereis brandti, a type of polychaete worm, according to Louise Page, a biologist from the University of Victoria in BC, Canada. Page listed sand‑dwelling habits as the typical behavior of the worms outside of mating season. The enormous size of the worms is off‑putting to would‑be adventurers, and reinforced by the presence of jaws which could deliver a painful bite thanks to the sharp appendages around the mouth. The swarming behavior gives rise to the fertilization of eggs and the appearance of tiny larval worms. Upon maturation, the worms may seem scary, but are actually most focused on eating algae. Their jaws are usually used to defend territory but offer only limited protection when the worms swim through the water, vulnerable to countless larger hunters.

7 Antarctic Scale Worm

Horror at the South Pole

Covered in bristles with dentacle jaws that look like something from the movie “Tremors”, the stubby, horrific‑looking Antarctic scale worm Eulagisca gigantea could certainly deliver a nasty bite. Growing nearly eight inches long, the marine worm’s scaly body acts as camouflage against the sea bed. But then it can rise up and attack prey with its proboscis which looks like a head with massive teeth. The hunter’s jaws efficiently rip into prey, serving as a powerful hunting tool that is a true concealed weapon. uses its jaws to rip into a variety of prey items, but if that is not enough, they are a true concealed weapon.

The worm can simply invert the appendage and pull it back into the body. Anytime there is an opportunity, outshoot the jaws. While the dentitions are not true teeth, being in an invertebrate, they are a pretty high‑quality likeness of a wolf’s fangs, albeit attached to a marine worm’s body. The creature is then partially beautiful in addition to being partially horrible‑looking. It is covered in bristly hairs that have a shiny golden appearance, offering an incongruous contrast to the worm’s monstrous capabilities. Prey items are simply ripped up by the sci‑fi‑worthy creature that has no problem remaining active in icy waters. With its fitting Latin binomial gigantea, the hefty creature can descend to depths of over 1,600 feet.

6 Fat Innkeeper Worm

The Ugly Guest Host

Known in common language as the Fat Innkeeper Worm, Urechis unicinctus is an awful‑looking creature, often compared to a penis in appearance. Yet its activities provide valuable habitat for a wide range of marine life that take refuge in the burrows they create. The bizarre worm is huge, bulbous, and beige and is named due to both its looks and the habit of creating horseshoe‑shaped burrows that serve as invaluable “inns” for a vast range of intertidal creatures. Gobies, other worm varieties, and even small crabs use the burrows, without harming or helping the fat innkeeper worm itself. The creature is a denizen of estuarine, brackish waters, and mudflats, hanging out around coastal wetlands that are unfortunately extremely vulnerable to climate change and development‑based disruptions.

The fat innkeeper worm feeds on plankton and is well known from the coast of California. Belonging to the phylum Echiura, the creatures may reach seven inches in length, large enough to startle beachgoers should be encounter one for the first time. In addition to maintaining “inns” for small creatures, the worms themselves are a veritable buffet course for larger visitors to wetlands, including bat rays, which suck up the worms, and opportunistic otters.

5 Multi‑Butt Worm

Ifs, Butts & Maybes

No ifs or maybes, but plenty of but(t)s? Yes indeed. There is a marine worm with one head and well over 100 derrieres, according to recent findings. The annelid worm species Ramisyllis multicaudata is distantly related to the familiar earthworm but inhabits oceans instead of gardens and lives in sea sponges that serve as hosts. Research published in the Journal of Morphology describes how the worms use the hollowed‑out interiors of marine sponges, an even simpler life form as a place of residence. How the worms feed is a matter of further research interest, given the lack of digested food found in the digestive tracts of the marine worms upon examination.

What is well documented is the importance of the many butts of the worms in reproduction, but not in the way you might expect. Each worm butt actually breaks away eventually and develops eyes and a brain before developing into a brand new worm that starts the life cycle over again. In extreme cases, the number of rears on a Ramisyllis multicaudata worm could be far more than reasonable imaginable. Up to 1,000 rear ends may be part of one worm.

4 The Burning Worm

Fire Under the Sea

Danger often comes in small bundles and that is the case with certain marine worms. While they only grow up to be about three to four inches in length, the worm community’s answer to the lionfish, scorpion, and stinging nettle is nothing to mess with. Found in warm tropical waters, Bearded fireworms Hermodice carunculata are covered in horrifying bristles that unload venom onto anyone or anything unlucky enough to touch them. Ouch! These toxic sea creatures are associated with Western and limited central Atlantic habitats that include coral reefs, under rocks, and even nestled in flotsam and jetsam drifting along the waves at sea.

The awful bristles are shiny and beautiful, having a resplendent appearance similar to a lionfish or sea anemone.  The worm’s hollowed‑out bristles effortlessly slide into the flesh of any creature that comes into contact with them and snap away, leaving bristles embedded. This causes mechanical and chemical irritation akin to being stung by a bee. To be fair, the worms do give out a warning first if bothered by first flaring out their bristles. Clearly, one of the laws of the sea to remember at all times is when in doubt, do not touch!

3 Parchment Worm

The Animal, The Machine

Looking like a literal paper dragon, the parchment worm Chaetopterus variopedatus constructs its burrow out of an extension of its body. While fragile, it is a strange mix of graceful and absolutely grotesque. The creature is gentle and feeds on plankton that it traps, and is not an aggressive hunter like many of the tougher worms in this account. Growing to about 10 inches in length, the worm is a bizarre but successful animal as a globally distributed generalist found in both tropical and cooler waters.

The feeding strategy of the parchment worm is decidedly odd. The worm’s body is formed by three sections, which include mouth and bristly body segments. Next, there is a structure that forms mucous and secreted mud‑based bags in the center, with segments that pump water into the body tube. Finally, a third section made up of many segments in a row concludes the body plan. The remarkably mechanical animals simply bag up food filtered from the water in mucous and mud “capsules” and swallow them like pellets for digestion.

2 Spaghetti Worm

A Rebel Among Worms

If you dumped a bowl of noodles on the seafloor, you would have a crazy‑looking creature that looks exactly like either spaghetti come to life, or even a crawling mop head. All you see are the tentacle‑like extensions as the worm winds along the seabed in search of meals. Unlike many marine worms, the spaghetti worm spends its life in the open, not needing the protection of a burrow. The creature is still in the process of being given a species name.

The discovery of the creature is fairly new, with the first sighting and description taking place during a research trip in the Gulf of California by the Monterey Bay Aquarium Research Institute (MBARI). This “dancing mop” may look vulnerable but apparently, the array of appendages allows the worm to collect small food items, all without having any eyes! The worm is a type of polychaete marine worm and belongs to the genus Biremis. Given the importance of polychaete worms in the marine environment, there is a World Polychaete Day which is July 1st to celebrate their existence. Footage of the mysterious Biremis species was first released on July 1st, 2012, nine years after MBARI researchers discovered it, marking the special day.

1 The Bobbit Worm

Worse Than Science Fiction

What creature bursts from the sea floor and grabs or even saws or scissors its prey right in half? The horrific Bobbit Worm Eunice aphroditois, armed with massive fangs that have a convergent resemblance to teeth can slice fish in half, right through the spine, and deliver a nasty bite if provoked. Stinging bristles just add to the nightmare. The worm is also dangerous to humans and should be viewed with great respect, not just curiosity. Drably colored segments of the worm are accented with iridescent highlights that add a dash of beauty to unimaginable ugliness.

The worm is akin to a viper, equipped with massive fang‑like pincers that are attached to the head. The force generated by the bite combines with the shocking striking speed to make encountering this animal a little bit like brushing into an underwater mine. In addition to the risks posed by a bite, the toxic bristles are capable of causing long‑term nerve damage if the animal is handled unwittingly. Disturbingly, this animal can on occasion reach 10 feet in length and weigh around one pound in the most extreme cases. That said, it is certainly possible larger and more vicious specimens are waiting to be discovered.
