Leatherback Turtles are the largest living marine reptiles and live almost their entire lives at sea. The only time that they are on land is when the female turtles lay eggs, and when hatchlings emerge from the nest and make their way to ocean.
Leatherbacks have the widest global distribution of all reptile species, and possibly of any vertebrate. They can be found in the tropic and temperate waters of the Atlantic, Pacific, and Indian Oceans, as well as the Mediterranean Sea.

Leatherback hatchlings look mostly black when you are glancing down on them, and their flippers are margined in white. Rows of white scales give hatchling leatherbacks the white striping that runs down the length of their backs.
Leatherbacks have a unique system of blood supply to their bones and cartilage. This enables their body temperature to stay several degrees above the water temperature and allows them to tolerate cold water, rather like a mammal.
The leatherback is listed as endangered by COSEWIC. Leatherback are endangered because of human interference—humans collect turtle eggs and create light pollution on beaches that disorients newly hatched turtles.
Habits: Leatherbacks feed almost exclusively on jellyfish, but also eat tunicates and seaweed. The mouth and esophagus have backward-pointing spines that aid in swallowing jellyfish.
Leatherbacks are strong swimmers and undertake long journeys - tagged individuals have been known to cross the Atlantic. After nesting the females circle the site, possibly to reinforce it in their memory to aid return.
