Capybaras are the largest of the rodent species. Weighing as much as a man, these oversized, pig-like animals are highly adapted to an aquatic lifestyle and even mate in the water. Capybaras are found over much of South America. Efficient grazers, they are able to crop even the short, dry grasses left at the end of the dry season. They are capable of a range of vocalisations and can purr and bark. Like rabbits, they eat their own dung to extract maximum nutrition from their food.

The capybara (Hydrochoerus hydrochaeris) is the largest rodent in the world, followed by the beaver, porcupine, and mara. Its closest relatives are agouti, chinchillas, coypu, and guinea pigs. Native to South America, the capybara inhabits savannas and dense forests and lives near bodies of water. It is a highly social species and can be found in groups as large as 100 individuals, but usually lives in groups of 10–20 individuals. The capybara is not a threatened species, though it is hunted for its meat and hide and also for a grease from its thick fatty skin which is used in the pharmaceutical trade.
