Deep Sea creatures of the Mariana Trench

Mariana trench - Barreleye
The barreleye, found at depths of 2000 feet, is most notable for its transparent head and highly sensitive eyes. The green lenses above each eye allow the fish to filter out what little sunlight makes it down to these depths and focus on the lights of its prey. (Source)

Mariana trench - Benthocodon

Mariana trench - Dragon Fish
I swear I can hear this fish go "MHUAHAHAHA" because of the front that looks like a hand!
Just like anglerfish, the dragonfish can produce its own light. The six-inch fish uses its flashing barbel (attached to its chin) to attract both prey and potential mates. The walls of its stomach are pitch black, to hide the light of any unlucky prey. (Source)

Goblin Shark
The terrifying goblin shark measures between 8 and 13 feet and was first discovered in 1898. Males can weigh up to 463 pounds. Scared yet? You should see how they eat... (Source)

Mariana trench - Grimpoteuthis - Dumbo Octopus
Mariana trench - unidentified anglerfish
The ear-like fins of this octopus have earned it the name “Dumbo.” The octopus lives at extreme depths of 10,000 to 11,000 feet, searching for worms and other crustaceans at the seafloor. Dumbo Octopii are about as cute as the Mariana Trench gets. (Source)

Mariana trench - unidentified species
Mariana trench Hatchetfish
The hatchetfish has special organs capable of producing their own light. They can be found at depths ranging from 600 to 4500 feet, which is the reason they need have such protruding, sensitive eyes. (Source)

Mariana trench - fanfin seadevil, fanfin seadevil
Although seadevils are part of the Anglerfish family, they don’t in fact have a lure. Males can only grow to about ½ an inch in length while the female can grow up to about 8 inches. Males will fuse themselves onto the female to breed and, like a parasite, share the female’s bloodstream. (Source)

These wonderful creatures have adapted to the dark. The make their own light, bioluminescence. In fact, if they wouldn't make their own light, the would stand out as a dark spot. 

They can be found in The Mariana Trench, which is located in the Pacific Ocean near Japan. It's 11.033 meters/36.201 feet or 6033,5 fathoms deep. The pressure at the deepest part of the Mariana Trench is over 8 tons per square inch. It's 2542 km/1580miles long and 69km/43 miles wide. The deepest part is called The Challanger Deep. It's named after the British exploration vessel HMS Challenger II. This depth was reached in 1960 by the Trieste, a manned submersible owned by the U.S. Navy.

(P.s. Okay, so the tag on this post is Arts/Books, I thought this was the best fitting tag.)

  6. YAY! I am obsessed with deep sea! Especially the dumbo octopus, why is it so cute?! I also think the goblin shark is kinda cute. He's like a unicorn, but of the sea. Like a Narwhal, but less cute. Some of the other creatures are scary looking blighters though. Thanks for sharing!!
