Mountain giant Sunda rat

The mountain giant Sunda rat (Sundamys infraluteus), also called the giant mountain rat or the giant rat of Sumatra, is a large rat with a total length of about 480 to 640 millimetres, of which the body is 230 to 290 millimetres, and a weight of 230 to 600 grams. That makes it somewhat larger than a Norway rat. It is mostly dark brown with paler brownish specks, long fur covered by even longer guard hairs, and a uniformly brown tail. It lives in forested mountains between 700 and 2400 metres, mainly in Indonesia and Malaysia, and it is omnivorous. Some scholars identify it with the giant rat of Sumatra that Arthur Conan Doyle mentions in The Adventure of the Sussex Vampire. The International Union for Conservation of Nature assessed it in 2016 as Least Concern.
