The Leatherback sea turtle, (Dermochelys coriacea), sometimes called the lute turtle, is the largest known of all living turtles (as well as the largest known extant sea turtle) and is the fourth largest known modern reptile behind three crocodilians. It is the only living species in the genus Dermochelys. It can easily be differentiated from other modern sea turtles by its lack of a bony shell. Instead, its carapace is covered by skin and oily flesh. The leatherback sea turtle is the only extant member of the family Dermochelyidae.

- Leatherback sea turtles are the largest living turtle on the planet. They must eat a lot of food to survive. They are Critically Endangered. They live in pelagic biome, but they can tolerate biomes such as the reef and costal biomes. The average size for these turtles is 1.7- 2.0 m. They weigh from 750- 1,530 lbs.
- Leatherback turtles have the most hydrodynamic body design of any sea turtle, with a large, teardrop-shaped body. A large pair of front flippers power the turtles through the water. Like other sea turtles, the leatherback's flattened forelimbs are adapted for swimming in the open ocean. Claws are absent from both pairs of flippers. The leatherback's flippers are the largest in proportion to its body among extant sea turtles. Leatherback's front flippers can grow up to in large specimens, the largest flippers (even in comparison to its body) of any sea turtle.

| - The Leatherback sea turtle, (Dermochelys coriacea), sometimes called the lute turtle, is the largest known of all living turtles (as well as the largest known extant sea turtle) and is the fourth largest known modern reptile behind three crocodilians. It is the only living species in the genus Dermochelys. It can easily be differentiated from other modern sea turtles by its lack of a bony shell. Instead, its carapace is covered by skin and oily flesh. The leatherback sea turtle is the only extant member of the family Dermochelyidae.
- Leatherback turtles have the most hydrodynamic body design of any sea turtle, with a large, teardrop-shaped body. A large pair of front flippers power the turtles through the water. Like other sea turtles, the leatherback's flattened forelimbs are adapted for swimming in the open ocean. Claws are absent from both pairs of flippers. The leatherback's flippers are the largest in proportion to its body among extant sea turtles. Leatherback's front flippers can grow up to in large specimens, the largest flippers (even in comparison to its body) of any sea turtle. The leatherback has several characteristics that distinguish it from other sea turtles. Its most notable feature is the lack of a bony carapace. Instead of scutes, it has thick, leathery skin with embedded minuscule osteoderms. Seven distinct ridges rise from the carapace, crossing from the anterior to posterior margin of the turtle's back. Leatherbacks are unique among reptiles in that their scales lack β-keratin. The entire turtle's dorsal surface is colored dark grey to black, with a scattering of white blotches and spots. Demonstrating countershading, the turtle's underside is lightly colored. Instead of teeth, the leatherback turtle has points on the tomium of its upper lip, with backwards spines in its throat to help it swallow food. Dermochelys coriacea adults average long and weigh . The largest ever found, however, was over from head to tail and weighed . That specimen was found on a beach on the west coast of Wales. Dermochelys coriacea exhibits a suite of anatomical characteristics believed to be associated with a life in cold waters, including an extensive covering of brown adipose tissue, temperature independent swimming muscles, counter-current heat exchangers between the large front flippers, and the core body, as well as an extensive network of counter-current heat exchangers surrounding the trachea.
