The leatherback is the largest, deepest diving, and most migratory and wide ranging of the sea turtles (Figure 2).
Description: Unlike other sea turtles, the bony shell of the leatherback is not visible. Instead, it is covered by a leathery layer of black or brown skin, hence their name. The shell has seven ridges running from front to back. Size: Leatherbacks are the largest of the extant (living) turtle species. They grow to over two meters in length and can weigh up to 2000 pounds.
