Patagonian mara, Dolichotis patagonum

The Patagonian mara, "Dolichotis patagonum", is a relatively large rodent in the mara genus. It is also known as the Patagonian cavy, Patagonian hare or dillaby. 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.
