The green sea turtle (Chelonia mydas), also known as the green turtle, black (sea) turtle, or Pacific green turtle,
is a large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name comes from the usually green fat found beneath its carapace; these turtles' shells are olive to black. -Wikipedia-
