How zoos meet the complex social and environmental needs of capybaras, the world's largest rodent and a highly gregarious semi-aquatic species.
Capybara welfare in zoos is generally positive where social groups are stable, water access is continuous, and diet is appropriate. Problems arise when groups are too small, access to water is limited, or social dynamics are destabilized by transfers or new introductions. The popularity of capybaras as interactive zoo animals creates the risk of excessive visitor contact that disrupts normal social behaviors. Facilities should establish clear visitor interaction protocols and maintain adequate private space for natural social activity away from public areas.
