7) Giant Isopod
A member of the crustacean family, the giant isopod resembles (and is actually related to) pillbugs that you find crawling around your garden. Unlike the insects in your garden, though, giant isopods can grow up to 16 inches long. This crustacean is a carnivore and scavenges its food form the ocean floor. As you may expect, these creatures roll themselves into a ball when they feel threatened, protecting their soft belly with their tough armor plating. Giant isopods live at depths of 2000 feet all over the globe.
The B.melanostomus, or coffinfish is covered from head to tail in spines to protect it from predators. It is one of the smaller creatures on our list, growing to 10cm in length, and while it lacks the long, sharp teeth of other deep sea predators, it is largely protected from other predators because of its prickly exterior. This fish lives at depths of 1320 to 1760 meters.
