Patagonia Cavy

Dolichotis patagonum

The Patagonian cavy, also known as the Patagonia mara, is a relatively large rodent.

This herbivorous, somewhat rabbit-like animal is found in open and semi-open habitats in Argentina, including large parts of Patagonia.

It is monogamous, but often breeds in warrens that are shared by several pairs.

The Patagonian cavy resembles a jackrabbit. It has distinctive long ears and long limbs. Its hind limbs are longer and more muscular than its forelimbs and it has a longer radius than humerus.

The feet are compressed, making them hoof-like. The forefeet have 4 digits while the hind feet have 3 digits. Its tail is short, depressed and almost hairless. It has a gray dorsal pelage with a white patch on the rump separated from the dorsal fur by a black area.

In addition, the mara has a white underside with a somewhat orange flank and chin. The mara has a head and body length of 27–30 in with a tail of 1.6–2.0 in. This rodent typically weighs 18–35 lbs.
