Capybara

The capybara is the largest rodent in the world, resembling a giant guinea pig. These semi-aquatic mammals are native to South America and are easily recognizable by their barrel-shaped bodies, short heads, and reddish-brown fur that helps them blend into their natural surroundings. Capybaras are highly social animals, often found in groups ranging from 10 to 20 individuals, although larger aggregations can occur. They are excellent swimmers, aided by partially webbed feet, and can hold their breath underwater for up to five minutes, which helps them evade predators. Capybaras are primarily active during the early morning and late afternoon, spending the hottest parts of the day wallowing in water or mud to keep cool. An interesting fact about capybaras is their symbiotic relationship with birds, such as the yellow-headed caracara, which feed on parasites found on the capybara's skin. This mutualistic interaction benefits both species, as the birds get a meal and the capybaras receive grooming.
