Meet the strangest and most unusual creatures of the deep. Yes, this creatures are for real but rarely seen.

1. Axolotl

#1. Axolotl

The Axolotl (or ajolote) (Ambystoma mexicanum) is the best-known of the Mexican neotenic mole salamanders belonging to the Tiger Salamander complex The species originates from the lake underlying Mexico City. Axolotls are used extensively in scientific research due to their ability to regenerate most body parts, ease of breeding, and large embryos.

2. The Blob Fish

Blob Fish 2

The blobfish (Psychrolutes marcidus) is a fish that inhabits the deep waters off the coasts of Australia and Tasmania. Due to the inaccessibility of its habitat, it is rarely seen by humans.

Blobfish are found at depths where the pressure is several dozens of times higher than at sea level, which would likely make gas bladders inefficient. To remain buoyant, the flesh of the blobfish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor without expending energy on swimming.

3. Cantor’s Giant Soft Shelled Turtle

Cantor’s Giant Soft Shelled Turtle

Called the Frog Head Turtle in Khmer language, the Asian Giant Softshell Turtle is easily recognized by its broad head, with eyes close to tip of snout. Its habitats are the river swamps, estuaries, and mudflats in lowland areas. Cambodia is believed to have a number of significant populations of this species. (source)

4. Clown Frogfish

Clown Frogfish

The Clown Frogfish or Antennarius maculatus is just one of the over 45 different species of Frogfish that inhabit our oceans. The coloration of the Clown Frogfish can vary by quite a bit. Some are brown or red, others yellow or purple and even a few white ones. You see, this fish actually has the ability to change its colors to blend in with whatever the colors of its habitat might be. They are not particularly large fish grow to only about 6″ in maximum length. Like other Frogfish this fish can actually walk along the bottom using its fins as legs! (source)

5. Dumbo Octopos

Living at a depth of 7,000 meter below sea level, the Dumbo octopus is the deepest-living octopi discovered. The octopuses of the genus Grimpoteuthis are sometimes nicknamed “Dumbo octopuses” from the ear-like fins protruding from the top of their “heads” (actually bodies), resembling the ears of Walt Disney’s flying elephant.

They are benthic creatures, living at extreme depths, and are some of the rarest of the Octopoda species. (source)

6. Giant Squid

Giant Squid

Giant squid live up to their name: the largest giant squid ever recorded by scientists was almost 43 feet (13 meters) long, and may have weighed nearly a ton. You’d think such a huge animal would be hard to miss. But because the ocean is vast and giant squid live deep underwater, they remain elusive and are rarely seen: most of what we know comes from dead carcasses that floated to the surface and were found by fishermen. (source)

7. Glaucus Atlanticus aka Blue Dragon

Glaucus Atlanticus (2)

This creature is a is a species of blue sea slug. You could find it in warm waters of the oceans, as it floats on the surface because of a gas-filled sac in its stomach.

Glaucus Atlanticus (3)

At maturity Glaucus atlanticus can be up to 3 cm in length

It is silvery grey on its dorsal side and dark and pale blue ventrally. It has dark blue stripes on its head. It has a tapering body which is flattened, and has six appendages which branch out into rayed, finger-like cerata. (source)

8. Goblin Shark


This rare shark is sometimes even called a “living fossil”, “is the only extant representative of the family Mitsukurinidae, a lineage some 125 million years old.” Goblin sharks inhabit around the world at depths greater than 100 m (330 ft), with adults found deeper than juveniles. Given the depths at which it lives, the goblin shark poses no danger to humans. (source)

9. Irrawaddy Dolphin

Irrawaddy Dolphin 2

The Irrawaddy dolphin is similar to the beluga in appearance, though most closely related to the killer whale. It has a large melon and a blunt, rounded head, and the beak is indistinct.

They are commonly found in discontinuous subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. (source)

10. Japanese Spider Crab

Japanese Spider Crab

The Japanese spider crab, Macrocheira kaempferi, is a species of marine crab that lives in the waters around Japan. It has the largest leg span of any arthropod, reaching up to 3.8 metres and weighing up to 19 kilograms. (source)

11. Lamprey


Lamprey are jawless fishes, representatives of an extremely ancient group of animals. In fact, there has been some sort of lamprey around for about 450 million years. The Lamprey’s face is dominated by a large sucking disk on the underside, heavily armed with rows of pointed teeth. (source)

12. Mint Shrimp

Mint Shrimp

Also called the “sea locusts“, “prawn killers” and even “thumb splitters”, this is one of the most common predators in tropical and sub-tropical waters; little is known about them, however, because of how much time they spend hiding in their burrows. (source)

13. Narwhal


This toothed whale, found in the arctic, has been valued for over 1000 years by the Inuit people for its meat and ivory. The narwhal, however, is especially sensitive to the climate change. (source)

14. Penis Snake

Penis Snake 2

This peculiar eyeless animal is actually called Atretochoana eiselti. It is a large, presumably aquatic, caecilian amphibian with a broad, flat head and a fleshy dorsal fin on the body.

Atretochoana eiselti is the largest known caecilian, attaining a length of 81 cm (32 inches), or more than twice the size of the next-largest known species. (source)

15. Red Lipped Batfish

Red Lipped Batfish 2

The red-lipped batfish gives the impression that it tried to compensate for an unusual body by caking on the lipstick.

Interestingly, they are better suited for ‘walking’ along the ocean floor than swimming. When they reach adulthood, they use their dorsal fin as a fishing lure to attract prey instead of for swimming. (source)

16. Sea Pig

Sea Pig (1)

Scotoplanes live on deep ocean bottoms, specifically on the abyssal plain in the Atlantic, Pacific and Indian Ocean, typically at depths of over 1000 meters. They are deposit feeders, and obtain food by extracting organic particles from deep-sea mud

Sea Pig (2)

Scotoplanes, like many sea cucumbers, often occur in huge densities, sometimes numbering in the hundreds when observed.

17. Snakehead Fish

Snakehead Fish

This scary looking fish is called a Snakehead. They are known for its voracious appetite, often consuming all other fish in a lake or pond and even eating its young. It can also slither across land and stay out of water for up to three days to find new sources of food. Once on land, snakeheads can eat almost any small animal in its path, and have even attacked people who got too close to snakehead egg nesting areas. (source)

18. The Atelopus Frog aka Harlequin Frog

This weird but amazing looking fish is considered a delicacy in many parts of the world. In Polynesia, it is served raw and was once considered “royal food”, only eaten by a King. (source)

20. The Giant Isopod

The Giant Isopod 3

This one is the largest of the existing isopods. “The enormous size of the giant isopod is a result of a phenomenon known as deep sea gigantism. This is the tendency of deep sea crustaceans and other animals to grow to a much larger size than similar species in shallower waters.”

The Giant Isopod 4

This bizarre animal is related to the common Pill Bug and, according to fossil record, have existed for over 160 million years. Even though it looks like these creatures could easily take over the world if they wanted to, they are actually quite harmless, deep-sea scavengers.

21. The Oarfish

The Oarfish

The Oar-fish also known as ribbon fish, are among the largest fish in the ocean, with some that can grow to up to 50 feet long. Because of its size, many believe sea serpent folklore and stories of mythological sea creatures originate with the oar-fish. If you’re worried that this image – which is now burned into your brain for eternity – will prevent you to ever set foot in the ocean again, don’t be. They commonly reside 3,000 feet deep, and sightings of this sea monster are extremely rare. (source)

22. The Pacu Fish

The Pacu Fish

Pacu is related to the meat-eating piranha, both sharing the same subfamily Serrasalminae, but they have different diets. Piranha is carnivorous proof of it are the sharp pointy teeth, while pacu is omnivorous with a squarer and straighter teeth like the humans.
