Degu

Octodon degus

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The degu is a hystricomorph rodent endemic to central Chile, related to the chinchillas and guinea pigs. It lives in colonies that dig communal tunnel systems and breed cooperatively: several females share a burrow and suckle the young indiscriminately. It is diurnal, highly vocal, with a repertoire of at least fifteen different calls, and feeds on grasses, seeds and bark. In recent decades it has spread both as a pet and as a laboratory animal.

Fun facts

  • GeneralHighly social and day-active; it cannot eat sugar, as it develops diabetes readily.
  • Its tail comes away if a predator grabs it, an autotomy that saves its life, although the tail never grows back.
  • It is one of the few rodents that spontaneously develops diabetes, cataracts and amyloid protein deposits similar to those of Alzheimer's, which has made it a key model in biomedical research.
