Mysteriously, there are many strange and spooky deep sea creatures living in the sea and ocean which we never know. We have only discovered just 3% of the whole percentage of sea and ocean on our planet. And we never know what is living there in the deeper water that humans cannot reach. But the thing I’m sure is the deeper the water, the scarier the creatures look.

Here are 18 eerie deep sea creatures that I want to introduce to you. And let us know which one you think is the best or the worse.

1Dragonfish

Dragonfish is a sea creature found in deep parts of the Atlantic Ocean. They live around 1500 to 4500 meters below the surface where no light reaches. This type of fish has a very minimalized skeleton except for the jaws and other feeding parts. They can also eat larger prey with the gifted flexible head and sharp teeth. Dragonfish is a predator since they live in where plants don’t grow.

2Frilled Shark

Yes, this is a shark. Frilled shark lives below 1200 meter in Atlantic and Pacific Oceans. They have an eel-like body and a strange appearance as you can see in the photo. Some people thought they are mythical sea serpent with their looks and habitats. Frilled sharks are caught in many locations in the Atlantic and Pacific Oceans, and they mostly come to feed on the surface at night.

3Giant Spider Crab

Giant Spider Crab or Japanese Spider Crab is a creature that lives in waters around Japan. They have the greatest leg span that estimated to be 5.5 meters from claw to claw. Pretty big for a crab, right? Not to mention these crabzillas can grow to a size of 40 cm with a weight of up to 19 kilograms. They live 300 meters deep in the water, and they have great tolerance to cold conditions as well.

4Atlantic Wolffish

The strong and fang-like of the upper and lower jaws bring the name Wolffish to them. This type of fish likes cold water which is why they live 20 to 500 meters deep. Their extremely strong jaws are powerful enough for them to ear hardshell mollusks, sea clams, and even large hermit crabs.

5Vampire Squid

Vampire squid has a black cloak that covers the 8 arms that connects to a webbing skin. And that is how they got the name, they have the cloak. This type of squid lives in lightless areas deep under the water of about 600 to 900 meters, or more. They are fast swimmers, and they have glowing arms along with great movements that make it difficult for predators to identify.

6Giant Grenadier

Here is the predator of the vampire squid and other squids in deep water. Giant Grenadier lives at depths between 140 and 3500 meters, and they look so spooky. They are found in the North Pacific, and more locations since they are populated everywhere. But I wouldn’t want to meet one of them.

7Fangtooth Fish

They look similar to Piranha for some reasons, but they quite small and harmless to humans. They live between 200 to 2000 meters deep in the water. Their eyes are relatively small which locates high on the head. They don’t look that scary, but they don’t look that nice either. Look at those teeth and eyes and that is why!

8Big Red Jellyfish

Yes, that is a jellyfish. Thank god they live at the depths of 600 to 1500 meters. This type of jellyfish can grow up to 76 centimeters. They have those thick fleshy oral arms in those long tentacles. Even if they are not that dangerous, but they are not a nice thing to get close to.

9Six-Gilled Shark

Sharks are never nice, that is the common thing that we all know. And right here is the unique shark that has six pairs of gill slits along with comb-like yellow lower teeth. They can grow up to 8 meters long, and they are found at the depths of 760 meters underwater.

10Blob Fish

You might know or hear about blobfish before. They have that face that resembles human somehow, and they live at depths of over 1200 meters deep. And of course, they always look this sad.

11Giant Tube Worm

Nope, these are not corals! They are giant tube worms that live at the temperature of 2 to 30 degree Celsius. They can reach the length of 2.4 meters, and can live over a hundred years.

12Pacific Viperfish

This is a nightmare I’m telling you. They mostly eat small fish, but their look is absolutely out of the earth. This type of fish has a large mouth, long fang-like teeth, and long dorsal fin rays. They live between 200 to 5000 meters below the surface.

13Giant Isopod

Giant creatures are not likely to be pleasant to see, for example, this giant isopod. They can grow up 17 to 50 centimeters, and they several legs. They live at the depth of 170 meters to 2500 meters where there is no single light reached.

14Star Gazer

That is a beautiful name for such an eerie deep water creature. Star gazer’s habit is under the sand where they bury themselves and catch prey. They can grow from 18 to 90 centimeters. The great thing is some of them can even deliver venom and electric shocks which make them even more mean.

15Chimaera

Chimaera or ghost sharks are found down 2600 meters deep in the water. They can grow up to 150 centimeters, and they are gifted with many sharp and replaceable teeth.

16Anglerfish

Anglerfish are known to have at least one long filament sprouting from the middle of their heads. That is called illicium. They use illicium to attract prey just like what you saw from Finding Nimo. They can grow from 20 centimeters to over 1 meter with a weight of 45 kilograms.

17Barreleyes

Also known as Spook Fish, they got the name because of their barrel-shaped and tubular eyes. They always look so relaxed and chill as you can see. They have a small toothless mouth, and they live about 400 to 2500 meters deep in the water. The large dome-shaped transparent head allows the eyes to collect more light while protecting the eyes.

18Black Swallower

I am surprised with the fact that this fish right here can swallow other preys no less than twice its size. Black swallower lives at a depth between 700 to 2745 meters, and they feed on bony fishes. It has this distensible stomach that allows it to swallow prey over twice its size and 10 times its mass. So greedy.
