The olive ridley turtle is similar in appearance to the Kemp’s ridley turtle, but it has a slightly deeper body and a nearly round carapace. The carapace is also upturned on the lateral margins and flat on top. The head of the olive ridley turtle is subtriangular and moderate-sized. Hatchling olive ridley turtles have relatively bigger heads, longer carapaces, and flippers that are comparatively bigger than in adults. They also have openings of the Rathke’s glands on the plastral bridges. Fore flippers of the olive ridley turtle have one or two visible claws on the anterior border, and sometimes another small claw in the distal part. Rear flippers also have two claws. Males have larger, more strongly curved claws, as well as a longer tail. The color of the olive ridley turtle is plain olive-grey above and creamy or whitish with pale grey margins underneath.
