The capybara is the largest rodent in the world. This semi-aquatic mammal lives in groups near rivers, lakes, and swamps in South America.
The capybara differs from other rodents by its very large size and adaptation to life in water. It is important for nature as the main consumer of grass and as food for jaguars, caimans, and anacondas.
