The common yellow-toothed cavy Galea musteloides is a wild guinea pig found in streamsides, savannas, bushland, and farmlands Rood , Redford and Eisenberg , Sachser et.

Its name is derived from the yellowish enamel color on the short incisors Walker Pelage is typically a darker agouti with a white belly. They have elongated hind feet with 4 toes and 3-toed front feet that are strong and flat Lacher Jr. The reason for this phenomenon is still unclear due to the lack of research on wild populations of G. Redford and Eisenberg have provided several mean morphological measurements.

The large submandibular gland sets Galea apart from other members of Caviidae. Females have 4 mammae Rood Galea has a widespread distribution and is common throughout its range. It can be found from southern Peru to northern Chile and north central Argentina Neris In Paraguay, it is mostly restricted to the western region throughout the Chaco Fig.

They reach sexual maturity by the age of months. Males mark females with secretions from their chin glands during the courtship process Redford and Eisenberg During breeding, it is not unusual for both males and females to exhibit aggressive behavior towards conspecifics.

Relative testis mass in males is one of the highest ever recorded in terrestrial mammals Schwarz-Weig and Sachser , Sachser et. Galea is diurnal, being most active at dawn and dusk. Its diet consists mostly of herbs and grasses Lacher Jr. Galea communities are a social hierarchy, with dominant males achieving a higher number of breeding opportunities.

Sympatric interactions have been observed on numerous occasions between Galea and Microcavia australis. The two species have been documented sharing runways, feeding together, and even grooming each other Rood , Redford and Eisenberg Due to its abundance, G. Cooper, T. Weydert, C. Yeung, C.
