Capybaras are the largest rodents in the world, native to South America. They typically weigh between 77 to 146 pounds and can grow up to 4 feet long. These social animals live in groups near water bodies like rivers and lakes, where they can easily escape predators. Capybaras are herbivores, primarily feeding on grasses and aquatic plants. They have webbed feet, which help them swim efficiently. Their friendly nature allows them to coexist peacefully with various animals, including birds and monkeys, making them a unique part of their ecosystem.
