Green sea turtles, so named for the colour of their skin, spend almost all of their lives under water. They are one of the most widespread turtle species found throughout the tropical and subtropical oceans of the world, and their ecology changes drastically according to the stages of their lives.

The newly emerged hatchlings crawl down to the sea from their beach hatcheries and live in the open sea feeding on small fish, crustaceans and jellyfish. Unusually, the adults are herbivorous, spending their lives grazing among the seagrass beds in shallower waters. Adult green turtles don’t have teeth but instead sport a finely serrated unhooked beak with which they can scrape algae off hard surfaces.
