Top 10 Creepiest Deep Sea Creatures That You Didn’t Know


The depths of the ocean floor are festooned with the most nightmarish deep sea creatures imaginable. Mariana Trench in the Pacific Ocean – is the deepest and darkest place on Earth – it’s so deep that even the Mount Everest – the highest point on Earth – if were dropped into it, its peak would still be more than a mile (1.6 kilometres) underwater.

Even at such incredible depths where there is no direct sunlight and the existence of life is totally unimaginable, there are creatures who survive, live and are the scariest deep sea creatures ever known to humans. Adaptation is the name of the game at such incredible depths – see how these deep-sea denizens make the most of their deep, dark home.

The following 10 are the deepest, scariest deep sea creatures list ever known to humans:

10. Stareater

These tiny creepy-looking fish with translucent fangs and no scales are found in Australia while exploring the ocean floor in 2015. Known as Stareater (also as Snaggletooths) is a predatory fish with delicate skin, and mouths filled with sharp, needlelike, curved teet.

They possess a bioluminescent red chin barbel (a whisker-like sensory organ near the mouth) that it uses as a lure to attract small prey into striking distance.

It’s an entirely new species of fish that has been discovered, with striking eyes and translucent skin.

9. Hatchetfish

The deep sea Hatchetfish gets its name from the distinct hatchet-like shape of its body. Of the several species of Hatchetfish that inhabit the ocean depths, the largest is known as the giant or large hatchet fish. This giant of the family grows to an impressive six inches (12 centimetres) in length.

Hatchet fishes are one of the many deep-sea creatures that have the ability to create their own light through a process known as bioluminescence.

They are found in most temperate waters of the world where they are found at depths ranging from 600 feet (180 meters) to 4,500 feet (1,370 meters).

8. Barreleye

Barreleyes, also known as spook fish, are small deep-sea argentiniform fish found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans.

Barreleye is also known by the name Spookfish. They are found 3330 feet down in the ocean and eat small fish, jellyfish.

Researchers at the Monterrey Bay Aquarium Research Institute (Bruce Robison and Kim Reisenbichler), who discovered the first live specimen of a barreleye fish back in 2004, put out a paper in 2009 showing that the eyes were able to rotate within the transparent shield.

7. Grenadier

Grenadier fish is the sea monster, because of their ugly structure and they smell very fishy.  Found at great depths from the Arctic to the Antarctic, members of this family are amongst the most abundant of the deep-sea fish.

They range in length from about 10 cm (3.9 in). The family of Grenadier fish as a whole may represent up to 15% of the deep-sea fish population with some 400 different species of Grenadier fish living at depths between 200 and 6,000 meters.

6. Blue Ringed Octopus

The blue-ringed octopodes are three octopus species that live in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia.

The blue-ringed octopus is not an aggressive marine animal. However, it’s always better to avoid handling this octopus because its sting contains tetrodotoxin, which paralyzes the victim. The sting is often fatal and injects its toxin by biting.

The southern blue-ringed octopus is often sighted in coastal waters at depths of up to 50 meters or even below depths. They weigh only 28 grams with bodies to 5 cm long and arms to 10 cm.

5. Megamouth Shark

The megamouth shark is a species of deepwater shark. It is rarely seen by humans and is the smallest of the three extant filter-feeding sharks alongside the whale shark and basking shark.

Known prey of the Megamouth Shark consists entirely of planktonic animals, including euphausiid shrimps, copepods, and the Pancake Jellyfish. Yet most plankton is found near the surface, so it is something of a mystery how Megamouth manages to find enough to eat.

4. Viperfish

deep sea creatures

A viperfish is any species of marine fish and are characterized by long, needle-like teeth and hinged lower jaws. A typical viperfish grows to lengths of 30 to 60 cm.

Viperfish are known to eat shrimp, squid, hermit crabs, anchovies, mackerel and other little fish. They swim at high speeds toward their prey impaling them with their sharp teeth. They live primarily in tropical to temperate waters.

3. The Black Swallower

deep sea creatures

The black swallower is a species of deep-sea fish in the family Chiasmodontidae. It is known for its ability to swallow fish larger than itself.

It has a worldwide distribution in tropical and subtropical waters, in the mesopelagic and bathypelagic zones at a depth of 700–2,745 m (2,297–9,006 ft).

2. Fangtooth

deep sea creatures

The fangtooth is found throughout the world in temperate and tropical ocean regions including the waters off the coast of Australia. It is one of the deepest living fish species yet discovered.

This scary creature haunts the deep waters of many of the world’s oceans. The fangtooth gets its name from its rather impressive looking teeth, which are actually the largest teeth of any fish in the ocean when taken in proportion to its own body size.

These scary fishes use their large pointy teeth to hunt squid and other small fish. These fish are found throughout the ocean. In temperate waters, as well as tropical waters.

1. Goblin Shark

deep sea creatures

The goblin shark is a rare species of deep-sea shark. Sometimes called a “living fossil”, it is the only extant representative of the family Mitsukurinidae, a lineage some 125 million years old.

The Goblin shark eats fish (both large and small), including other sharks and rays. They also eat squid and crustaceans (like crabs). The Goblin shark has long, sharp teeth in the front of its mouth.

Goblin Sharks live at the bottom of the ocean along the continental shelf. They can grow up to 12 feet long and weigh up to 460 pounds. They have narrow snouts and fang-like teeth.
