10 Most Frightening Looking Deep Sea Creatures

Have you ever been in the ocean and get an unnerving chill from something brushing against your leg? Although the ocean is fun to swim in, its inhabits have us a bit afraid to have close interaction. The deep blue sea is full of animals that look terrifying when compared to land animals. Below is a list of the Top 10 Most Frightening Looking Sea Creatures currently swimming ocean waters!

10 – Pacific Blackdragon

Basically, this creature looks like a long black stick with a creepy head attached to the top of it. Although this creature isn’t big when compared to the human body, it still has a frightening face! It has pale eyes and sharp teeth. Its stomach is designed with black coloring because most of the prey it eats is bioluminescent.

09 – Dragonfish


Surprisingly, Dragonfish eggs are buoyant so these creatures are born at the surface. Thankfully, it goes back down to the depths because its displaced teeth and menacing face are scary to look at. Its lower jaw has an attached barbel that produces light with photophores for illuminating light. You don’t need those bumping into your feet!

08 – Snaggletooth

There are not many words to describe this creature than a burnt-looking body, pale eyes, and teeth. It is just ugly! It can produce its own light because of the darkness of the depths from which it lives.

07 – Megamouth Shark

This deep sea creature is new to the world as it was recently discovered in 1976 and is rarely seen. It hasn’t been classified because of this. Just as the name suggests, it has a big mouth. Sharks plus big mouths are always a scary combination.

06 – Vampire Squid

The name is misleading; these creatures don’t suck blood; they don’t even ink like another squid. Its appearance is the only aspect that makes it look frightening. The vampire squid’s tentacles make a big, umbrella-like opening. Can you imagine that floating above you?

05 – Sarcastic Fringehead

This fish isn’t exactly big and doesn’t pose a threat to people but its defensive technique is so surprising, it looks alarming. When agitated, or threatened, it will open a massive mouth that is both wide and long to expose lines of teeth. Although colorful, it will make you want to look away.

04 – Grenadier

These fish are stinky more than anything. Due to high levels of Trimethylamine oxide, they have a pungent order. They can live in depths of up to 1,000 meters. To say the least, their appearance and big, gaping mouth just look scary.

03 – Frilled Shark

These creatures are known as living fossils and they certainly look prehistoric! Its head is thick like a head, similar to a snake’s body and the long frame ends with a frilled tail. The frilled shark’s teeth are peculiar looking but that is no issue for it. Scientists believe the creature lunges at prey like a shark and swallow it whole.

02 – Gulper Eel

Eels are kind of scary to look at already but the gulper, or pelican, eel puts them to shame. It keeps the long, snake-like body but what is at the beginning of the body looks like it swam out of your nightmares. It has a big head with a long, sharply angled jaw. Its mouth can stretch long enough to swallow creatures larger than itself.

01 – Goblin Shark

This shark is a big “nope”! Spiky teeth poke out of its square jaws that are placed beneath a big, sword-like nose. Although rare, it has been caught by fishermen a few times. It is fit for its name and takes a top spot as one of the most frightening looking creatures of the sea!
