The capybara is most associated with wet, tropical wilderness like the Amazon Rainforest, but its range extends to every country in South America except Chile. It's one of well over a hundred mammal species found here on the massive flooded grassland known as the Pantanal—a biodiversity hotbed at the intersection of Brazil, Bolivia, and Paraguay. The world's largest rodent happily adapts to urban habitats, too, so it's hardly an uncommon sight in the continent's many growing metropolises.
