The Leatherback sea turtle is an amazing "soft shelled" sea turtle. It differs from the other sea turtles we see in the Florida Keys because of it's size and shell. Leatherbacks are larger than other hard shelled species of turtles and they have a unique leather-like shell that can compress and expand as they make deep dives, sometimes over 3000 feet! They thrive in deep ocean water, eating their favorite food- jellyfish! Unfortunately, they are susceptible to being caught in commercial fishing drift nets. These large sea turtles are protected under the Endangered Species Act.
