Green Turtle

The green turtle is the largest species in the family of hard-shelled sea turtles and second largest to the leatherback turtle among all sea turtles. Its common name comes not from the color of its skin or shell, which is common among most sea turtle species, but from the greenish color of its fat. The green turtle is the only sea turtle that is a strict herbivore, and its diet of seagrass and algae may contribute to the green fatty tissue.


Similarly to other sea turtles, green turtles are known to travel incredibly long distances during their lifetimes. In some cases, individuals may travel across entire ocean basins from their feeding areas to nesting beaches in the tropics and sub-tropics. Green turtles use the earth’s magnetic field like an invisible map to navigate throughout their migrations. Like other marine turtles, female green turtles return to the same beach where they hatched to nest. The two largest remaining nesting areas (in terms of numbers of nesting females) for green turtles are the Caribbean coast of Central America and the Great Barrier Reef in Australia.


Females will lay about 100 eggs per clutch and will nest several times over a few weeks. Once the eggs hatch, baby green turtles will make their way to the water and swim to offshore areas, where they will live for several years. Once juveniles reach a certain age and size range, they will leave the open ocean and travel to nearshore foraging grounds, where they shift to being primarily herbivores with a diet mainly consisting of seagrasses and algae. Both juvenile and adult green turtles are generally found nearshore, especially in areas w
