Abrocomidae
(Family)Chinchilla rats are members of the family Abrocomidae. They resemble Chinchillas in appearance, with a similar soft fur and silvery-grey color, but have a body-structure more like a short-tailed rat. They are social, tunnel-dwelling animals, and live in the Andes Mountains of South America. They are probably herbivorous, although this is not clear[1].
Some molecular work [2], suggests that, despite their appearance, they may be more closely related to octodontoids such as degus, nutria, and tuco-tucos than they are to chinchillas and viscachas.
