Green Sea Turtle
EndangeredThe green sea turtle is one of the largest sea turtles and the only herbivorous species among them. They are named not for the color of their shells, but for the greenish color of their subdermal fat, which is stained by their diet of seagrasses and algae. Green sea turtles migrate incredibly long distances between feeding grounds and the nesting beaches where they were born. Their streamlined shells and paddle-like flippers make them exceptionally graceful swimmers.
