The southern big-eared mouse (''Loxodontomys micropus''), also known as the southern pericote, is a species of rodent in the family Cricetidae. It is found in Argentina and Chile, and is one of only two species in its genus. The type specimen was captured by Charles Darwin in 1834 along the Santa Cruz River in Argentina, during the voyage of the HMS Beagle, and was subsequently described by George Robert Waterhouse.〔 ==Description== The southern big-eared mouse has a relatively heavy build for a mouse, accentuated by its thick fur. Fully grown adults of both sexes range from in total length, including the tail, and weigh between . It is however, not unusual for individuals to reach sexual maturity long before they reach the full adult size.〔 The fur is dull greyish-brown over most of the body, with paler greyish or yellowish underparts. As its name suggests. it has larger ears than many other local species of mouse, although they are not dramatically so. The feet are sturdy, and the fifth toe on the hind feet is unusually long. The tail is about three-quarters the length of the body, and is covered with sparse fur. It can most readily be distinguished from other nearby mouse species by its robust build, relatively long tail, and the absence of hair on the feet. Females have four pairs of teats, running from the axillary region down to the groin.
