Hippopotamuses in zoo settings have highly specific aquatic habitat requirements and social needs that many facilities struggle to meet, creating welfare challenges for one of Africa's most distinctive megafauna.
Hippo welfare in captivity centers on access to adequate water depth and area, appropriate social grouping, and management that respects their natural hierarchy. Facilities with insufficiently deep pools force hippos into abnormal postures and deny the thermoregulatory and sensory functions of their aquatic adaptation. Appropriate exhibit design requires significant investment but is essential for the welfare of animals that spend the majority of their lives in water.
