Chris relaxes with Charlie, a capybara (Hydrochoerus hydrochaeri), also known as the giant water guinea pig. The Capybara is the world’s largest rodent, achieving a weight of up to 160 pounds. Charlie lives in the forest near the ExplorNapo Lodge on the Sucusari River in the Peruvian Amazon. He likes to cadge snacks from visitors to the area, and enjoys having the backs of his ears scratched. He is free to come and go as he pleases, and bathes regularly in the river.
