Kemp's ridley sea turtle

Kemp's ridley sea turtle (Lepidochelys kempii ), or the Atlantic ridley sea turtle, is the rarest species of sea turtle and is critically endangered. It is one of two living species in the genus Lepidochelys (the other one being L. olivacea, the olive ridley sea turtle).

Anatomy

Kemp's ridley is a small sea turtle species, reaching maturity at 58–70 cm (23–28 in) carapace length and weighing only 36–45 kg (79–99 lb). Typical of sea turtles, it has a dorsoventrally depressed body with specially adapted flipper-like front limbs and a beak. The Kemp's ridley turtle is the smallest of the sea turtles, with adults reaching a maximum of 75 cm (30 in) in carapace length and weighing a maximum of 50 kg (110 lb). The adult Kemp's ridley has an oval carapace that is almost as wide as it is long and is usually olive-gray in color. The carapace has five pairs of costal scutes. In each bridge adjoining the plastron to the carapace, there are four inframarginal scutes, each of which is perforated by a pore. The head has two pairs of prefrontal scales. Hatchlings are black on both sides. The Kemp's ridley has a triangular-shaped head with a somewhat hooked beak with large crushing surfaces. This turtle is a shallow water benthic feeder with a diet consisting primarily of crabs.
