Green turtles (Chelonia mydas) live in the warm coastal waters of tropical and subtropical oceans. Adults sometimes eat sponges, salps (floating jelly-like animals), and jellyfish, but they feed mostly on plants, like seagrass and algae. The pigment from this green diet colors their fat, giving them their common name.
Populations of female nesting green sea turtles are estimated to have dropped by 48% to 65% in the past 100 to 150 years. However, recent studies show that marine protected areas are benefitting the turtles.
