The flatback sea turtle (Natator depressus) is a sea turtle located along the sandy beaches and shallow coastal waters of Australia. They can only be found in the waters around the Australian continental shelf. It belongs to the family Cheloniidae, along with other sea turtles. This turtle gets its name from the fact that their shell has a flattened or lower dome than the other sea turtles. They can be olive green to grey with a cream underside. These turtles average from 76 cm to 96 cm in length and can weigh between 70 kg to 90 kg. The hatchlings, when emerging from nests, are larger than other sea turtle hatchlings when they hatch. The flatback turtle is listed as Vulnerable. They are not Threatened like other sea turtles due to their small dispersal range.
