It is said that more remains to be discovered of the mysterious oceans, than anywhere else on earth. Creatures, the likes of which have never been seen, inhabit so much of our oceans. At times it is difficult to study such creatures of the deep, because they can be elusive. Thanks to the advancement of technology, the study of deep dwelling sea creatures is now a reality. Who knows what remains to be seen?
Prickly Shark

Little is known about these passive sharks. It's a bottom dwelling shark that resides in the Pacific Ocean. It has two small dorsal fins and lacks an anal fin. They live at depths of more than 3,000 feet. It's called the prickly shark because of protruding spines on the scales of the upper body.
Glowing Sucker Octopus

It uses luminescent lights to attract prey. They range from a black to reddish color. Their fins resemble elephant ears.
Vampire Squid

The stuff made of nightmares. It looks like a cross between a octopus and a squid. It has eight arms like an octopus, and two flaments like a squid, used for hunting. It is a deepwater species that can grow to a foot in length. It is also capable of turning itself inside out, but scientists are confounded by this odd behavior.
Oarfish

The oarfish is an extremely large, elongated fish. One was listed in the Guiness Book of World Records for having been over 12 feet in length. It is the longest bony fish and can grow to be 50 feet in length.
Goblin Shark

The most distinctive shape of the shark is its abnormally shaped head. It has a long snout unlike other sharks. It is a deep dwelling animal and has a pink tinge to its flesh.
Ctenophores

They're known as comb jellies. Technically they are not jellyfish, since they have no stinging cells. They do have connective tissues and a nervous system.
Long-nose Chimera

It has an unusual shaped snout, which it uses to detect prey. They are a primitive fish and closely related to sharks.
Spotted Handfish

This fish has fins that actually look like hands. Even though the fish can swim, it uses these little “hands” to gallop along the sea floor.
Megamouth

The first of its kind was discovered in 1976, which is recent in the terms of scientific discovery. And only 39 have been caught or sighted since 2007. These shy sharks are so mysterious, that little is known about them.
Grimpoteuthis

Known as “dumbo” octopuses because of its ear-like fins, they are deep dwellers. There are only 14 types of grimpoteuthis, and little is known about their species.
Benthic Squid

They are distinctive in that they have exceedingly long arms. They are fairly elusive. It was first discovered in 1907, but the specimen was badly damaged, and not much could be learned from it.
