The leatherback turtle is the largest sea turtle in the world. Unlike other turtles, it does not have a hard shell made of horn plates, but a leather-like skin with longitudinal ridges. It can reach enormous depths and primarily feeds on jellyfish.

The body is dark gray to black with white spots. The carapace is elongated and traversed by several rib structures. The front flippers are very large and allow for long migrations over thousands of kilometers.
Large sharks and orcas, especially in juveniles
Not toxic and harmless to humans.
Leatherback turtles can regulate their body temperature better than other reptiles and therefore can also be found in colder waters. Some animals cross entire oceans between feeding and breeding areas.
