The capybara is the largest rodent in the world, native to South America. It is a semi-aquatic mammal, often found near rivers, lakes, and wetlands. Known for its calm and friendly nature, the capybara is highly social and usually lives in groups. They are herbivores, feeding on grasses and aquatic plants. Capybaras are excellent swimmers, using their webbed feet to move through water with ease. Their peaceful demeanor makes them popular among both humans and other animals.
