Patagonian mara to the anus. The Patagonian mara is found only in Argentina. It ranges from 28ºS to 50ºS. Maras prefer to live in habitats with lots of shrub cover. However they also inhabit overgrazed and barren soils in the Monte Desert biome. In northwestern Argentina the mara primarily inhabits lowland habitats like forest and creosote bush or "larrea". Maras prefer sandy and low shrub habitat in Valdes Peninsula. It has adapted well to a cursorial lifestyle on the open plains and steppe, with its long legs, reduced clavicle and well-developed sensory organs making it capable of running and communicating in these
Monte Desert other two nearby deserts. The geography of the land is very similar to that of the interior Patagonian Desert, with volcanic sediments, piedmont plains, large mountain blocks and many usually dry salt lakes.
