Originally thought to be a pig, the Capybara is now classified as a rodent – in fact the world´s largest rodent, standing 60 cm (2 ft) tall at the shoulder and weighing in up to 80 kg (175 lbs). A close relative to the guinea pig, the Capybara lives in Central and South America, where it roams swampy, grassy regions bordering rivers, ponds, streams and lakes.
