Rattus argentiventer
rice-field rat

Rattus argentiventer is found throughout Southeast Asia.

Rice field rats primarily reside in cultivated areas such as rice paddies and grasslands. It is largely dependent on human rice fields and plantations. Rice field rats shelter in burrows in soil, under rocks, and in logs. They make nests from hollowed-out heaps of material, often in a burrow. (Nowak 1991, Barnett 1975)

Rattus argentiventer is a medium-sized rat with grizzed yellow-brown and black pelage that is not spiny when stroked. Its belly is grayish in the midline with whiter flanks. The dorsal sufaces of its hind feet are about the same color as its back and often have a dark spot or line. The tail is uniformly medium brown. Rattus argentiventer is 304-400mm long with a tail length of 140-200mm and a skull length of 37-41mm. (Van Peenen 1969)

Rattus argentiventer lives in large groups with a social hierarchy of dominant males and a few high ranking females. Groups are territorial. Rattus argentiventer has a vocal repertoire consisting mainly of squeals and whistles used in aggressive encounters. (Nowak 1991)

Rattus argentiventer is omnivorous, with a diet that includes termites, grasshoppers, snails, insects, rice, seeds, nuts, vegetables, and fruit. (Nowak 1991, Grzmick 1990)

Rattus argentiventer is often responsible for depredations on rice fields and gardens. It is the fourth most damaging rodent to rice crops. (Grzmick 1990, Nowak 1991)

Rattus argentiventer has no special conservation status.
