It is found in Argentina, Bolivia, Chile, and Peru. It's karyotype has 2n = 68 and FN = 136. "G. musteloides" is the most common and widely found member of "Galea", and is present at elevations ranging from 20 to 5000 m above sea level. It has yellow teeth. A recent study reveals there are five subspecies of "G. musteloides": "boliviensis", "demissa", "leucoblephara", "littoralis" and "musteloides".

Muenster yellow-toothed cavy social play with their offspring and groom them rather than being aggressive. When mothers of this species and their pups are put into a strange environment, the presence of the mothers mitigates increases in blood cortisol levels in their pups; however, this is not observed when the pups are moved together with other mothers that are not their own. "G. monasteriensis" is both sexually and socially monogamous. Both males and females of "G. monasteriensis" defend their territories and care for their pups.
