The least pygmy squirrel (Exilisciurus exilis), also known as the plain pygmy squirrel, is a species of rodent in the family Sciuridae.[2] This plain olive-brown squirrel is endemic to forests, mostly below an altitude of 750 m (2,500 ft) but locally significantly higher, on the Southeast Asian islands of Borneo, Sumatra and Banggi.[3][4] Together with the African pygmy squirrel, the least pygmy squirrel is the smallest squirrel in the world, having a total length of 10–14 cm (3.9–5.5 in) and a weight of 12–26 g (0.42–0.92 oz).[3]
