The Leatherback Turtle (Demochelys coriacea)

It is the largest of all the sea turtles, between 4 to 8 feet long, and weighs between 500 and 2000 lbs. It has a smooth, leathery, flexible carapace (shell), and is the only sea turtle with no scutes (scales). It is the only one of the species that has longitudinal ridges down the carapace. The shell is black with gray, white or pink spots. These animals have the furthest migration route of all the sea turtles, traveling about 10000 miles a year from Asia to the West Coast of the USA. The Leatherbacks are currently listed as critical endangered, and are at risk to be extinct in the next 20 years.
