The capybara (Hydrochoerus hydrochaeris) is the world’s largest rodent, found in South America, particularly in wetlands and grasslands. Weighing up to 65 kg, it has a stocky body with short fur that ranges from brown to reddish-brown. Known for its social and gentle nature, capybaras live in groups near water, where they often graze on grass and aquatic plants.

Capybaras are herbivores and play a role in plant control, especially in wetland ecosystems. They are prey for various predators, such as jaguars and caimans, and are important for maintaining the balance of their habitats. Capybaras are not currently threatened but face risks from habitat loss and hunting
