Chinchillas are two species of crepuscular rodents, slightly larger and more robust than ground squirrels. They are native to the Andes mountains in South America and live in colonies called "herds" at high elevations up to 4,270 m (14,000 ft). Historically, chinchillas lived in an area that included parts of Bolivia, Peru, Argentina, and Chile, but today colonies in the wild are known only in Chile. Along with their relatives, viscachas, they make up the family Chinchillidae.
The chinchilla (whose name literally means "clay") is named after the Chincha people of the Andes, who once wore its dense, velvet-like fur. By the end of the 19th century, chinchillas had become quite rare due to hunting for their ultra-soft fur. Most chinchillas currently used by the fur industry for clothing and other accessories are farm-raised.
Both species of chinchilla are currently listed as a critically endangered species by the IUCN Red List of Threatened Species due to a severe population loss approximated at a 90% global population loss over the last 15 years. The severe population decline has been caused by chinchilla hunting by humans. Until 1996, they were listed as Least Concern on the IUCN Red List. By 2006 they were listed as "Threatened", and in 2011 they became "Critically Endangered".
The two living species of chinchilla are Chinchilla chinchilla (formerly known as Chinchilla brevicaudata) and Chinchilla lanigera.C. chinchilla has a shorter tail, a thicker neck and shoulders, and shorter ears than C. lanigera. The former species is currently facing extinction; the latter, though rare, can be found in the wild. Domesticated chinchillas are thought to have come from the C. lanigera species.
Formerly, chinchillas occupied the coastal regions, hills, and mountains of Chile, Peru, Argentina, and Bolivia. Overexploitation caused the downturn of these populations, As early as 1914, one scientist claimed that the species was headed for extinction. Five years of fieldwork (published in 2007) in Jujuy Province, Argentina, failed to find a single specimen. Populations in Chile were thought extinct by 1953, but the animal was found to inhabit an area in the Antofagasta Region in the late 1900s and early 2000s. The animal may be extinct in Bolivia and Peru, though one specimen found (in a restaurant in Cerro de Pasco) may hail from a native population.
