The Pataginian Mara (Dolichotis patagonum), a somewhat rabbit-like animal resembling a jackrabbit, is found in open and semi-open habitats in Argentina, including large parts of Patagonia. It is the world's third largest rodent after the capybara and beaver. Its feet are compressed, making them hoof-like – the fore feet have four digits while the hind feet have three digits. It prefers arid grasslands and brush lands with a great deal of open space.
