Leatherbacks have the widest global distribution of all reptile species and inhabit every ocean except the Arctic. They can be found in the tropic and temperate waters of the Atlantic, Pacific and Indian oceans, as well as the Mediterranean Sea. Female leatherbacks return to their natal beaches during breeding season to nest and lay their eggs.
Leatherbacks primarily eat jellyfish, but also feed on other soft-bodied organisms, such as tunicates and cephalopods — and sometimes floating plastic bags, which can be deadly.
Leatherbacks are the largest turtles on Earth, growing up to 2.5 metres long and exceeding 900 kilograms. Leatherbacks can dive to depths of 1,280 metres — deeper than any other turtle — and can stay down for up to 85 minutes.
