Capybaras are the largest rodents in the world, and the only one left of their species. Found only in the tropics of South America north to Panama, they are excellent swimmers.
Capybaras are semiaquatic, living near ponds, rivers, or swamps and feeding on aquatic plants. They associate in groups of 10 or more individuals, and at times several groups may forage together, forming a much larger herd.
