Giant toirtoise

The leatherback sea turtle , sometimes called the lute turtle, is the largest of all living sea turtles and the fourth largest modern reptile behind three crocodilians. It is the only living species in the genus ''Dermochelys''. It can easily be differentiated from other modern sea turtles by its lack of a bony shell. Instead, its carapace is covered by skin and oily flesh. ''Dermochelys coriacea'' is the only extant member of the family Dermochelyidae.
