The Green sea turtle (Chelonia mydas), or honu, is a large sea turtle belonging to the family Cheloniidae. Their common name derives from the green fat found beneath their carapace.
Many honu nest at the protected French Frigate Shoals some 800 kilometers (497 mi) west of the Main Hawaiian Islands.
Swimmers, surfers, and beachgoers in the Main Hawaiian islands will often see adult honu feeding on seaweeds on nearshore reefs.
Marine debris is a hazard for these animals. The turtles can become entangled in drifting trash and drown.
