Green Sea Turtle

The green sea turtle is a large sea turtle and the only species in its genus. The name refers to the usually green fat beneath the shell, from a diet of seagrass, not to the carapace, which is olive to black. The flattened body is covered by a large teardrop-shaped carapace, and it has a pair of large paddle-like flippers. It is the only sea turtle that is herbivorous when fully grown (Wikipedia, general species account).

Adults usually live in shallow lagoons and feed mostly on seagrasses. Across its range the species migrates long distances between feeding grounds and nesting beaches. Females come ashore at night to dig nests and lay eggs, and hatchlings scramble into the sea. Those that reach maturity may live to about 90 years. The Reptile Database gives its range as the Atlantic, Pacific and Indian oceans, chiefly in the tropics, and Wikipedia lists India among the major Indian Ocean nesting countries.
