Zoo & Captive Animal Welfare

Zoo Hippopotamus Aquatic Welfare

Hippopotamus aquatic welfare requires deep, clean water for submersion, thermoregulation, and skin health. This is a non-negotiable welfare requirement for this semi-aquatic species.

Key Facts

Hippos spend up to 16 hours daily submerged in water in the wild
Full submersion is required for thermoregulation as they have no sweat glands
Hippo skin secretes a natural sunscreen that requires water for maintenance
Pool water quality must be maintained for skin health and disease prevention
Social management of hippo groups requires appropriate space for conflict avoidance

Welfare Considerations

Hippo aquatic welfare is a fundamental requirement that cannot be compromised. Only facilities able to provide large, deep, clean pools with full submersion opportunity should keep hippopotamuses.
