Sea Pig

Sea pigs live on the bottom of the ocean floor. They aren’t, of course, acutally pigs but sea cucumbers. While it looks like the sea pig has legs, they are the same kind of tubes that help all sea cucumbers get around.

This strange creature lives deep off the coast of Australia. Sadly, deep-sea fishing has pushed the blobfish to the edge of extinction.

The anglerfish gets its name from the prey-attracting bioluminescent “fishing pole” on its head.

What’s even more fascinating about the deep-sea anglerfish is the unusual way their mating habits evolved. Females, like the one pictured above, are a few centimeters long. Males, on the other hand, are significantly smaller and can only survive when attached to a female’s body. In fact, when scientists discovered female anglerfish, they were puzzled by the unusual “parasites” attached to them; only later did they realize that they were actually the males!

The glass squid’s transparency is, as you may have guessed, a defense mechanism. Kinda looks like a mouse, doesn’t it?!

The longest legs of all the arthropods, the Japanese spider crab’s legs can have measured up to 12 feet long! Despite their fierce appearance, the Japanese spider crabs are said to have a “gentle disposition.”

Giant Isopod

The creature that launched a thousand nightmares, the discovery of the giant isopod in 1879 was crucial to the science of the deep sea. Indeed, the giant isopod was the first confirmation that things could live in such deep waters. The creepy critter can be up to 2 and a half feet long!

The Japanese Spider Crab has a gentle disposition? Yeah, no, I wouldn't try tickling its tummy. And the blob fish looks like an old boss of mine. :)

The giant isopod looks like a dust mite. I noticed some creatures appeared to be dead. Why do they have to kill things to show us?
