chinchilla rat
Chinchilla rats or ''chinchillones'' are members of the family Abrocomidae. This family has few members compared to most rodent families, with only 9 known living species. 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.
They can be described as medium-sized. Stiff hairs project over the three middle digits of the rear feet. Their massive skulls narrow in the facial areas.〔Allaby, Michael. ''The Concise Oxford Dictionary of Zoology.'' pg 1. Oxford University Press. New York. 1992.〕 Some molecular work, 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.
==Etymology==
The family name is derived from the Ancient Greek word ἁβροκόμης (''habrokomēs'', "with delicate hair"). The word ἁβρός (habros) means "delicate, graceful" and the word κόμη (''komē'') means "hair".
