Taxonomy[ edit ] The number of species of mountain viscachas was considered to be three by most authors: L. However, taxonomy usually differs by authors e. The distribution is shown to be the Andes mountains in Peru at elevations between 3, and 5, m.

References Geographic Range Lagidium peruanum, one of several recognized species of "Mountain Viscachas," lives in the Andes Mountains of Peru at elevations ranging from approximately 3,, meters.
This corresponds to the area contained between the timber and snow lines. It is not uncommon to have dense populations separated from other such populations by over 10 kilometers. There is seemingly little or no difference in habitat structure between occupied areas and the unoccupied areas between populations. Biogeographic Regions native Habitat L. Vegetation is relatively sparse and characterized mainly by coarse grasses. They occupy burrows among rocks and crevices. Terrestrial Biomes mountains Physical Description L.
They posess dense, soft fur on their bodies and long, coarse fur on the dorsal surface of their tails. Their pelage coloration varies from dark grey at low elevations to brown at higher elevations. The ventral portion of their fur is lighter, and can be white, yellowish, or light gray. The dorsally curled ends of their tails vary from rusty to black in color. Females have only a single pair of mammae. Other Physical Features.
