About the Green Sea Turtle

The green sea turtle is a large marine reptile found in tropical and subtropical oceans worldwide. It is named not for its shell but for the greenish fat beneath it, a result of its largely plant-based adult diet of seagrass and algae. Powerful flippers make it a graceful, far-ranging swimmer, capable of migrating thousands of kilometers between feeding grounds and the beaches where it hatched. Females return to those natal beaches to lay eggs. Long-lived but slow to mature, green turtles are endangered and protected across much of their range.
