World's biggest living rodent and close relative of the guinea pig. A freakin' HUGE brown rodent found in the marshes of South America; looks like a cross between a brown guinea pig and a cow (with duck feet). The rodentine answer to the hippo--cattle egrets have even been seen perched on their backs. Favorite food of the anaconda.
The capybara herd roamed the Peruvian floodplains, wading through mud and grunting like buffalo.

The largest rodent in the world. Standing 2 feet (60 centimeters) tall at the shoulder and built somewhat like a barrel with legs, the “capy” has long, light brown, shaggy hair, a face that looks like a beaver’s, no tail, and slightly webbed feet. Originally thought to be a pig of some sort, we now know that the capybara is a rodent, closely related to cavies and guinea pigs.

Also known as the 'water pig.'
Water is a source of life for the capybara, as the animal eats water plants and grasses and uses the water itself to escape from danger. In fact, a capybara can stay underwater for up to five minutes at a time to hide from predators.
The capybara is wallowing in shallow water and mud to keep cool.
