Top 10 Scariest Ocean Animals In The World


The ocean is a scary place.

We’ve only explored less than 5% of the ocean to date. It’s the lifeblood of our planet, covering more than

70% of the Earth’s surface. And we haven’t even scratched the surface, literally, of what lurks beneath this deep blue sea.

That’s why it’s so frightening to know that the animals found on the list are just the beginning of what we will find in the dark, murky depths of the abyss.

Top 10 Scariest Ocean Animals In The World


CERATIOID ANGLERFISH scary ocean creatures

Way down in depths of the ocean, marine scientists have found a new fish species that is flat out ugly.

This fish has a large rod attached to its head to lure other fish into its spiky jaws. It’s the kind of predator you never want to encounter.

This fish is found at depths of up to nearly 5,000 feet where waters are pitch black. No plants grow there and the only creatures that survive there feed off of waste from food above that fall from the surface down to the pitch-black sea floor in tiny particles not too different than snowflakes. 


BOX JELLY FISH scary creatures

Box jelly fish are some of the most lethal jelly fish on the planet. According to the U.S. national science foundation, more than 100 or more people die each year around the world from the many species of box jelly fish.

In Australia, one type of box jelly fish can have dozens of tentacles, each up to 15 feet long with enough toxin to kill 60 people.

Each year, along the coast of Florida, you’ll find thousands of these jelly fish. And there’s been many people put in the hospital from them – some have died.

In fact, some say these jellyfish are more lethal and kill more people than sharks! 


Great White Shark

This list wouldn’t be complete without the Great White Shark…this beast is responsible for the spawn of Hollywood films for the last half century. Plenty of people have been frightened from ever visiting a beach again. It doesn’t take much more than watching the evening news to learn of a new attack. Every year, surfers and beachgoers are attacked by these giants. There’s been over 280 fatal white shark attacks in the world.

While this giant predator of the ocean is feared, it’s also one of the most threatened species on the planet. Fisherman from countries like Japan, hunt sharks to feed restaurants with shark fin soup and other bizarre foods.

Scientists today track the migratory trends of these sharks and are continuing to learn more about them to help swimmers and tourists at the beach avoid a meeting with the Great White during migratory seasons. 


Saltwater Scary Ocean

The list wouldn’t be complete without mentioning the salt water crocodile. They have earned a reputation as one of the fiercest predators. Unlike alligators, these beasts can grow up to 20 feet long and weigh nearly 3,000 pounds. Their primary attack mechanism is a death roll where crocodiles kill their prey by latching on with their jaws while performing a devastating powerful twisting roll. This will break apart large animals and even humans!

You can find these Salt Water Crocodiles in places like Florida where they can grow on average up to 13 ft.

But in other parts of the world, these beasts can grow up to 20 feet and have occasionally been known to hunt people in local villages. 


Leopard seals are the top predators in the Antarctic. You don’t want to go swimming near one of these. Lapboard seals are furious predators and just like Great White Sharks, are very curious. Once you enter their territory, they want to get to know you (and not in a good way).

In 1985, a Scottish Explorer named Gareth Wood was bitten twice on the leg when a leopard seal tried to drag him off the ice and into the sea. And in 2003, snorkeling biologist Kirsty Brown was drowned after a Leopard seal dragged her to her death in the frozen waters. 


scary jellyfish

Recently, scientists discovered what seems to be a kind of Deepwater jellyfish. What makes this so scary is that we truly don’t know what it is.

Most experts believe it was a type of jellyfish but it swims too fast to be anything close to what science knows is possible.

The unidentified sea creature (USC) was filmed by a deep sea camera while performing repairs to an underwater oil Rig in the Gulf of Mexico. 


A frilled shark swims in a tank after being found by a fisherman off Japan's coast in 2007. One of the rare creatures was recently caught in Australia, shocking fishermen.

They look like sharks before they learned how to be a shark. And if that didn’t scare you, these creatures are rarely found in shallow water. But when they do, they usually scare the wits out of you!

These alien sharks live deep in the middle layers of the ocean. It’s possible a lot of myths and legends of serpents come from the frilled sharks. Rows upon rows of teeth – 25 rows with 300 teeth! They can eat things more than half their body weight! And can eat like a snake. 


SeaLion Scary Animals

Don’t ever get near a Sea Lion, especially if they are near baby Sea Lions. These creatures are known to be extremely territorial.

A Diver off the coast of Santa Barbara, California had a close encounter with an aggressive sea lion while spearfishing. The encounter was caught on film. The diver barely escaped with his life.

The National Ocean and Atmospheric Administration advises the Public to stay at least 50 yards away from them while swimming. 


GULPER EEL scary animals


Eels are never fun to see in the ocean. Bu the Gulper Eel is a deep-sea monster who usually lives at 3,000 meters below the ocean and can grow up to six feet long!

Why are they terrifying? Because with the large jaws and pelican like mouth, they can swallow prey up to six feet long with their super stretchy stomachs! 


Goblin Shark Scariest Ocean Animal

The goblin shark lives up to 1,300 meters below sea level. They are similar to Frilled Sharks but grow up to 3.5 meters long. They are terrifying because they can detach their whole mouth from their body to catch prey!
