Why is the leatherback turtle so called
�
A.� The leatherback turtle, Dermochelys coriacea, unlike all other turtles, has no obvious shell and its back is merely skin, which has a blackish smooth leathery surface, hence the name.
�
Q.� But aren't shells a defining feature of turtles
A.� Yes, all turtles are partly classified as such by their shells, or carapace. The leatherback's shell is internal, buried in its skin. The flexible bony plates are set on ridges: seven across the back and five across the underside.
�
Q.� What advantages does the leatherbacks internal shell provide
A.� The leatherback dives deeper than any other turtle. Its shell protects its internal organs from being crushed by the increased water pressure experienced a such great depths.
�
Q.� Are leatherbacks endangered
A.� Yes, they're on the endangered species list. Adult turtles are rarely killed for meat,�but in some coastal areas of the Indian, Pacific and Atlantic oceans where they live, we humans�eat their eggs.
�
They're also at risk from getting caught up in fishing nets and from dying after mistaking the numerous pieces of rubbish floating in the seas for jellyfish
�
Q.� How big are leatherbacks
A.� They're the largest of turtles, growing up to 2m long and 540kg in weight. From one tip of their front flipper to the other can span a total of 2.7m.
�
Q.� Other than jellyfish, what do leatherbacks eat
A.� They also eat other soft-bodied sea animals, as well as plants.
