Annandale's rat

Annandale's rat, Sundamys annandalei, is a species of rodent in the family Muridae, the large family that holds most of the world's rats and mice. It is found in Indonesia on the island of Sumatra, in Peninsular Malaysia and in Singapore. It was classified as Rattus annandalei until 2017, but mitochondrial and nuclear DNA show that it belongs to the rat genus Sundamys, so it is now placed in that genus rather than in Rattus. The Wikipedia article that describes it is a short stub and gives no figures for habitat, body size, lifespan, diet or population.
