Leatherback sea turtles are the largest living marine reptiles and live almost their entire lives at sea. The only times that they are on land is when the female turtles lay eggs, and when hatchlings emerge from the nest and make their way to ocean. Leatherback turtles are different from other sea turtles in that they have a soft, cartilaginous shell rather than a hard bony one. It is from the appearance of the shell that the "Leatherback" name comes. They have a more streamlined shape and larger flippers than other sea turtles, reflecting their more migratory and pelagic lifestyle.
