Gilbert's potoroo or ngilkat (Potorous gilbertii) is Australia's most endangered marsupial and one of the world's rarest critically endangered mammals. It is a small nocturnal macropod that lives in small groups. It has long hind feet and front feet with curved claws, which it uses to dig for food. Its body has large amounts of fur, which helps with insulation, and its fur ranges between brown and grey, the colour fading on its belly. This potoroo has a long, thin snout curving downward that it uses to smell its surroundings; this trait is common in all potoroo species. Its eyes appear to bulge out of its face and look as though they are on an angle, and its ears are almost invisible, buried under thick fur. Male and female body types are similar and are both within the same size range. Ad
