Abrocoma cinerea
ashy chinchilla rat

Chinchilla rats, Ambrocoma cinerea are restricted to the Altiplano of the Andes of South America, from Southern Bolivia and Peru into Central Chile. (Myers, 1999)

Chinchilla rats are restricted to the Altiplano region of the Andes, they occur in rocky areas between 3700 and 5000 meters. Burrows can commonly be found under rocks or at the bases of shrubs. (Encarta, 2000; Nowak, 1991).

Chinchilla rats range from 15 to 25 cm long, not including the tail, which can be from 6 to 18 cm long. They weigh 200 to 300 g. Chinchilla rats have large, round ears and large eyes, the head is elongate. Limbs are short with 4 digits on the forefoot and 5 on the hindfoot. The fur is thick and soft,silver-gray in color above and white or yellow underneath. The fur is similar in texture to a chinchilla's, though less desirable in the fur trade. (Encarta, 2000; Nowak, 1991)

Very little is known about reproduction in Abrocoma cinerea. The length of gestation ranges from 115 to 118 days with 1-2 young per litter. (Grzimeck, 1975; Nowak, 1991)

Chinchilla rats live in small colonies of about six. Burrows may be only 18 meters apart. They communicate using a variety of sounds including grunts, squeaks, and gurgles (Encarta, 2000; Nowak, 1991).

Chinchilla rats are herbivorous and nocturnal. The diet includes seeds, fruits, and nuts. Though primarily terrestrial, they are capable of climbing as well. (Encarta, 2000; Encyclopedia Britannica Online, 2000)

There is no great economic importance to humans. Skins of chinchilla rats are sometimes sold at fur markets but are not of much value (Nowak, 1991).

Chinchilla rats are somtimes hunted for pelts. There is no true commercial value but they are sometimes sold to travelers as true Chinchilla. For this reason, and because of habitat destruction, they have become rare. (Nowak, 1991).
