The fore legs are tetradactyl, as well as the hind ones, however, the latter have the very short fifth digit. The fur is dense and soft. Up to 60 hairs may grow from a single hair follicle. The colouration on the back is bluish-gray with black tint. There are a lot of long black or gray vibrissae. Chinchillas live in colonies of up to 100 animals. The females are very aggressive towards the other animals in the group, and even during the mating season, they are often aggressive towards the males. Despite this, the serious fights happen rarely in nature, because the animals simply go away. The animal is domesticated. The wild long-tailed chinchilla is in the IUCN Red List as critically endangered (CR).
