The capybara is the largest rodent in the world, native to South America. They typically weigh between 77 to 146 pounds and can grow up to 4 feet in length. Capybaras are semi-aquatic animals, often found near rivers, lakes, and wetlands, where they enjoy swimming and foraging for grasses and aquatic plants. These social creatures live in groups of 10 to 20 individuals, which helps protect them from predators like jaguars and anacondas. Capybaras are known for their friendly nature and often coexist peacefully with other animals, including birds and monkeys, making them a unique part of their ecosystem.
