Introducing. 17 Deep Sea Creatures Ever Discovered. It’s been said that 95% of the waters in the world remained unexplored. And the deepest parts of the Oceans especially are a challenge to unravel. This is because, reaching the far depths of the oceans pose a lot of biological and engineering challenges, so anything discovered or that comes out of its dark depths seem to look bizarre and almost alien-like to us.

So, let’s take you through a list of 17 deep sea creatures ever discovered. Don’t worry, they aren’t proven to migrate anywhere close to the beaches where people spend a lot of their summertime.

These are the top 17 deep-sea creatures ever discovered…

17. Frilled Shark

 Frilled Shark

More like Thrilled to me, this species of sharks are rarely encountered by human as they prefer to remain in the deep depths of the ocean, up to 5,000 feet (1,500 meters) below the surface. The last Frilled Shark found in shallow water was back in 2007, in Japan.

Although it died few hours after its capture and transport to a marine park, the 5.3-foot (1.6-meter) specimen was considered a living fossil, bearing many characteristics of extinct ancestors who swam the seas during the prime of Dinosaurs.

16. Giant Spider Crab

Giant Spider Crab

Giant Crabs are usually big, believed to be the largest anthropods on the planet. They can measure up to an incredible 12 ft. (3.7 meters) from their claw tip to claw tip. Native to the Japanese waters, these very rare, leggy behemoths giants enjoy to spend their time scrounging on the floor of the ocean up to 30,000 (300 meters) in depth. This five-foot (1.5-meter) specimen was photographed in Japan’s Sagami Bay.

15. Atlantic Wolffish Pair

Atlantic Wolffish Pair

At number 15th position is a marine fish of the wolffish family Anarhichadidae. This minacious-looking sea creature can be found in the rocky coastal depths of the oceans up to 1,600 ft (500 meters). They can stretch up to 5 ft. (1.5 meters) in length, and have a set of blatant dentition that they use for feeding, cracking hard-shelled mollusks, crabs, and sea urchins. The fish is also called the seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel, and woof or sea cat.

14. Fangtooth Fish

Fangtooth Fish

Okay, before I say anything about this devilish, piranha-looking fish, I just want to ask. Did God had to go on and create this too? They don’t just look nightmarish, they are also among the deep-sea creatures to be discovered.

They make their home range as high as about 6,500 feet (2,000 meters). But, they have also been found swimming at icy, crushing depths near 16,500 feet (5,000 meters). This sinister-looking fish species can grow up to about 6 inches (16 centimetres) long.

13. Six-Gill Shark

Six-Gill Shark

The Six-Gill shark or as often times called, Cow shark, is the largest hexanchoid shark, and they can grow up to 16 ft. in length. They are mostly seen swimming deep down on the ocean floor during the day, cruising at depths of 8,200 feet (2,500 meters), before moving to the surface at night to hunt for food. They are found in tropical and temperate waters worldwide and feed on a diet of other sharks, rays, crabs, and seals.

12. Giant Tube Worms

Giant Tube Worms

These marine invertebrates in the phylum Annelida live on the floor of the Pacific ocean, close to crushing pressures, freezing temperatures, and zero sunlight with extremely high hydrogen sulfide levels.

11. Vampire Squid

Vampire Squid

This deep-sea creature is rarely seen, but if they are, it’s probably in the lightless depths of the ocean. They can swim comfortably at depths of more than 10,000 ft. (3,000 meters) below the surface, navigating the blackness of the depth of the ocean with the help of their unique retractile sensory filaments, and eyes that are very large.

Considered a living fossil due to the creature’s relatively unchanged nature compared with its fossilized ancestors that lived 300 million years ago, the Vampire Squid are found occupying the mesopelagic and bathypelagic regions of temperate and tropical world oceans.

10. Pacific Viperfish

Pacific Viperfish

If you think the Fangtooth fish is bizarre-looking, take a look at this predatory fish with jagged, needle-like teeth so conspicuous it can hardly close its mouth. It lives in the abyssal depths of the deep sea and can reach up to 8 inches (25 centimetres) long.

They can be found lurking the ocean depths up to 13,000 feet (4,400 meters) below, luring prey with their bioluminescent photophores on their bellies.

9. Dragonfish


At number 9 is one of the top predators in the deep sea, ‘the Dragonfish’. They are a scary-looking creature and they emanate red beams of light from their eyes while lurking the darkest parts of the depths of the ocean. The bizarre-looking fish is capable of producing its own light through a method known as bioluminescence, which it uses to lure its prey as a lantern draws in moths.

8. Big Red Jellyfish

 Big Red Jellyfish

This species of Jellyfish named Tiburonia granrojo was discovered by a crew from MBARI led by George Matsumoto. It is a genus of Jellyfish in the family Ulmaridae. They are very huge and can grow over 1 meter in length and carry a slight red coloration.

Unlike its other Jellyfish relatives, this species of Jellyfish is armed with a series of fleshy “Feeding Arms” that it uses to hunt down prey.

7. Blob Fish

Blob Fish

We’ve seen ugly and terrifying, and then there’s the blobfish. This species of fish is by far the most hideous sea creatures that exist in the depths of the sea. Found in the deep waters off the coast of mainland Australia and Tasmania, as well as the waters in New Zealand, the blobfish don’t grow more than 50cm in length and they live at depths of over 1200 meters. I don’t blame them anyway for choosing to live so deep in the sea depths. I mean, if I were to be that ugly, I would also hide from the rest of the world.

6. Coffinfish


The weird list of some of the deep Sea creatures discovered continues with our next mention, the Coffinfish. It is a member of the sea toad family Chaunacidae and is found in salty waters of the southern Pacific, off the east coast of Australia. These fish puff itself if it feels threatened and uses its fleshy protrusion to lure its prey.

5. Giant Isopod

Giant Isopod

This creepy-looking sea creature can be found in abundance, creeping along the depths of the cold, dark, deep waters of the North Atlantic, Pacific, and the Arctic circle.

4. Stargazer

The deep sea creatures list just keeps getting creepier and creepier. They are not just famous for being ugly, they are also very deadly, and they have two large venomous spines located at the back of their opercles and above their pectoral fins.

During their hunt, they bury themselves in the sand and leap upwards to deliver a surprise attack on their prey as it swims by. And another thing, the species of this fish are electric, which means they can deliver deadly shocks.

3. Chimaera


Often referred to as ‘ghost sharks’, this species of underwater creature used to swim throughout the world’s ocean. However, today, they are mostly situated in deep water.

2. Pelican Eel

Pelican Eel deep sea creatures

Okay, this particular one right here scares me out! You probably have never seen or heard about this creature before, have you? Are you starting to ask the question “What kind bizarre discovery of nature is this?” Well, the Pelican Eel or the Gulper Eel is a deep-sea fish that is rarely seen by humans.

However, if you like going on fishing trips in the deep and open sea, you might just get lucky and catch yourself a few. This deep sea creature is one of the strangest looking creatures lurking don in the depths of the deep sea. This sea creature is capable of swallowing things much bigger than itself due to its enormous mouth that opens wide.

1. Megamouth Shark

Megamouth Shark deep sea creatures

And the last on the list but certainly not the last is the Megamouth Shark. This species of shark was discovered in 1976 and are very rare. Hardly to be seen by human eyes and is the smallest compared to the other three extant filter-feeding sharks alongside the whale shark and basking shark. The most noticeable feature of this fish is its large mouth which it uses to swallow plankton and smaller fishes.
