Montane guinea pig Montane guinea pig The montane guinea pig, "Cavia tschudii", a type of rodent, is a guinea pig species from the Andes in South America. The montane guinea pig is the likely ancestor of "Cavia porcellus", the cavy or domestic guinea pig. Peruvian wild guinea pigs were first described by E. T. Bennett in 1835, who termed them "Cavia cutleri". Johann Jakob von Tschudi, in an 1845 publication, used the term "Cavia cutleri" to refer to what are now considered two separate entities - the first, Bennett's "Cavia cutleri", which was later (by Oldfield Thomas in 1917) identified as probably a
Muenster yellow-toothed cavy Muenster yellow-toothed cavy The Muenster yellow-toothed cavy (Galea monasteriensis) is a species of rodent in the family Caviidae. It is known only from one location in Valle Hermoso in the Bolivian Andes, at an elevation of 2557 m. Specimens from this location were shipped to Muenster, Germany in 1997 for laboratory research, where the species was recognized and described. "Galea monasteriensis" was recognized on the basis of morphological, behavioral, and reproductive differences from related species. However, its habits in the wild have not been studied. Unlike the :common yellow-toothed cavy and :Spix's yellow-toothed cavy, Muenster yellow-toothed cavy males engage in
