Distribution:

Mostly widely distributed species in the country with Turtle Island, Tawi-tawi as a major nesting ground (>1,000 nestings recorded annually). All sub-tropical seas.

 

Diet:

Their serrated upper jaw effectively scrapes filamentous algae off hard bottoms, and shears leafy seaweeds and seagrasses. Green turtles have an active gut flora to assist them in breaking down otherwise undigestible vegetative matter.
