Common Yellow-toothed Cavy

Galea musteloides

Least Concern

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

Spotted something wrong?

The common yellow-toothed cavy is a caviomorph rodent related to the guinea pig, widespread across Argentina, Bolivia, Peru and northern Chile. It lives in colonies that make use of other animals' burrows and of runways opened through dense vegetation, and is active by day. It feeds on grasses and leaves. Its young are born well developed, with fur, their eyes open and able to eat solid food within hours, a strategy typical of South American rodents that do not depend on a safe burrow.

Fun facts
