SCIENTIFIC NAME: Natator depressus

The flatback sea turtle is named after its flat carapace, or shell, which is unlike the more curved shell of other sea turtle species.

The carapace is pale grayish-green in color with the outer margins distinctly upturned.

An adult flatback weighs approximately 200 pounds (90 kg) and is roughly 3 feet (0.9 m) in length.

They have the smallest distribution of all the species and breed and nest only in Australia.
