Capybaras are the largest of living rodents. Capybaras are herbivores and are very gentle. It was common to see other animals sitting on the back of a Capybara, so that it is often referred to as “moving chairs”. The scientific name of Capybara is Hydrochoerus hydrochaeris, which means "water hog". This indicates that the Capybaras are good swimmers and looked slightly like the pigs, despite that they are really the relatives of the mice. Capybaras are important in the ecosystem and they are preferred prey of large predators.
