Description

Chinchillas are either of two species (Chinchilla chinchilla and Chinchilla lanigera) of crepuscular rodents of the parvorder Caviomorpha. They are slightly larger and more robust than ground squirrels, and are native to the Andes mountains in South America. They live in colonies called "herds" at high elevations of 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. They are also related to the chinchilla rat. The chinchilla has the densest fur of all mammals that live on land. In the water, the sea otter has a denser coat. The chinchilla 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 after being hunted for their ultra-soft fur. Most chinchillas currently used by the fur industry for clothing and other accessories are farm-raised. Domestic chinchillas descended from C. lanigera are sometimes kept as pets, and may be considered a type of pocket pet. Formerly, chinchillas occupied the coastal regions, hills, and mountains of Chile, Peru, Argentina, and Bolivia. Overexploitation caused the downturn of these populations and, 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. In their native habitats, chinchillas live in burrows or crevices in rocks. They are agile jumpers and can jump up to 1.8 m (6 ft). Predators in the wild include birds of prey, skunks, felines, snakes and canines. Chinchillas have a variety of defensive tactics, including spraying urine and releasing fur if bitten. In the wild, chinchillas have been observed eating plant leaves, fruits, seeds, and small insects.
