Capybara

The capybara (Hydrochoerus hydrochaeris) is a large rodent of the genus Hydrochoerus of which the only other extant member is the lesser capybara (Hydrochoerus isthmius). The capybara is the largest rodent in the world. Close relatives are guinea pigs and rock cavies, and it is more distantly related to the agouti, chinchillas, and the coypu. 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 and is hunted for its meat and hide and also for a grease from its thick fatty skin which is used in the pharmaceutical trade.
