The Green Sea Turtle is one of the largest of the marine turtles and the only herbivore among the different species, feeding mostly on sea grasses and algae (although when young, they also eat worms, crustaceans and aquatic insects).

Green Sea Turtles are found mainly in tropical and subtropical waters. Like other sea turtles, their migrations cover long distances between feeding grounds and the beaches from where they hatched. They can be distinguished by the single pair of scales in front of their eyes. 

Classified as vulnerable in NSW and nationally, Green Sea Turtles are threatened by harvesting of their eggs, hunting of adults, vessel strike, being caught in nets, especially from commercial shrimp trawling, climate change and the loss of beach sites for nesting. Their eggs incubate inside nests for about 60 days before hatching and minimal disturbance for this duration is critical. Mature females nest about every two years.
