Giant naked-tailed rat

The giant naked-tailed rat (Uromys anak) is a rodent in the family Muridae that lives on the island of New Guinea, where it is found in West Papua in Indonesia and in Papua New Guinea. It occupies tropical forests and wetlands and can also survive in degraded forest. Oldfield Thomas described it in 1907 from a specimen collected at Efogi on the Brown River in what was then British New Guinea, at an altitude of about 1,219 metres. The Mammal Diversity Database also calls it the black-tailed giant rat, places it in the genus Uromys of the tribe Hydromyini, and records its IUCN Red List status as Least Concern.
