A Giant Guinea Pig?
The capybara is the world’s largest rodent, so capybara are related to guinea pigs and squirrels. Capybara have webbed feet which makes them excellent swimmers. Their eyes and nostrils sit high on the face, allowing them to spend time underwater and still look for jaguars or other predators.
Capybaras mainly eat grasses and aquatic plants. In some areas they are considered pests by farmers because they raid fields of sugarcane and watermelon.
