Capybaras are semi-aquatic rodents requiring substantial water access for thermoregulation, skin health, and expression of natural behaviour.
Capybaras without adequate water access experience skin problems, thermoregulatory stress, and inability to express core natural behaviours including aquatic socialising and predator escape response. The welfare standard for capybaras must include water deep enough for full submersion and large enough for the entire social group to use simultaneously.
