Known as the giant rodent and scientifically, Hydrochoerus, capybara is a partially aquatic rodent found dwelling in the swamp regions of Central and South America. The capybara is said to be in the same family of other rodents, like Chinchillas, Guinea Pigs, etc. also available in South America. It is the largest rodent species in the world. It weighs about 75 kg and it is almost 1.4 meters long. Though a capybara is huge in size, it can properly swim in water. These mammals have some distinctive features that support their amphibious nature, which includes the web-like skin. The web-like skin is between their toes that helps them swim better. It is not much surprising that capybaras are also called ‘water hogs’.
