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.
The two living species of chinchilla are Chinchilla chinchilla (formerly known as Chinchilla brevicaudata) and Chinchilla lanigera. In nature, chinchillas live in social groups that resemble colonies, but are properly called herds. Herd sizes can range from 14 members up to 100, this is both for social interaction as well as protection from predators. They can breed any time of the year. Their gestation period is 111 days, longer than most rodents. Due to this long pregnancy, chinchillas are born fully furred and with eyes open. Litters are usually small in number, predominantly two.
The international trade in chinchilla fur goes back to the 16th century. Their fur is popular in the fur trade due to its extremely soft feel, which is caused by the sprouting of 60 hairs (on average) from each hair follicle. The color is usually very even, which makes it ideal for small garments or the lining of large garments, though some large garments can be made entirely from the fur. (source: Wikipedia)
