Malayan field rat

It is a common species and the International Union for Conservation of Nature has assessed it as being of "least concern". The Malayan field rat has a head-and-body length of 140 to 190 mm (5.5 to 7.5 in) and a tail 150 to 200 mm (6 to 8 in). It has a weight of between 55 and 150 g (2 and 5 oz). The ears are large and nearly naked. The fur is smooth and flattened, interspersed with short spines. The dorsal pelage is a grizzled olive-brown with scattered medium-length black guard hairs, and the underparts are whitish. The tail, which is a similar length to the body, is a uniform dark brown. The feet are broad, and the soles have fine ridges for climbing.
