Fun Facts
1. The capybara is the world's largest living rodent.
   
2. Capybaras are proficient swimmers, swimming with only their nostrils, eyes, and ears above the surface. They are also known to swim underwater - sometimes for considerable distances.
   
3. Capybaras are social animals, living in groups of 6-20 and occasionally congregating in aggregates as large as 100 individuals. Social groups are controlled by a dominant male whose social status is vigorously and aggressively maintained.

Ecology and Conservation
 

While often hunted for its meat and hide, the capybara remains widespread and common. Commercial ranches raising capybara have seen modest interest. Capybara ranches have the ecological advantage of maintaining areas while engaging in commercial pursuits.
