The green sea turtle inhabits warm waters worldwide. This species, like most sea turtles, is pelagic spending nearly their whole life at sea. Green sea turtles, named for the color of their flesh, can grow to reach nearly 5 feet (1.5 M) and can weigh up to 450 lbs (205 kg). Adult green turtles are herbivorous feeding on algae and sea grass. Juveniles, however, are known to eat a variety of aquatic invertebrates.
