The largest living rodent, the Capybara makes her home near water in most of South America. She is semi-aquatic, and has partially webbed feet. Her nostrils too, are high on her head, allowing her to fully submerge except for her eyes, nose and ears. Indeed, she can even sleep in the water. Highly gregarious, she lives in herds with other females, juveniles and several adult males. Together they selectively graze the forest, grassland and water plants.
