Leatherback seaturtle

Selina Heppell

Latin name: Dermochelys coriacea

The leatherback sea turtle is the world's largest living sea turtle, weighing up to 800 kilograms (1,500 lbs!). Leatherbacks roam the oceans eating jelly organisms, even in high latitudes because they can maintain body temperature higher than sea water. In the Pacific, leatherbacks have declined steeply, but in the Northern Atlantic and Caribbean, most populations are stable or increasing. Dr. Selina Heppell developed population estimation tools with the Leatherback Expert Working Group of NOAA Fisheries.

Did you know? The Leatherback has a leathery back instead of a hard shell. Their deepest dives have been recorded at 4,200 feet.
