Pygmy hippos are secretive, solitary forest dwellers from West Africa. With fewer than 2,500 remaining in the wild, zoo populations are conservation-critical and must meet specialist welfare requirements.
Pygmy hippo welfare in captivity requires attention to humidity, water access, nocturnal management, and reproductive biology. Skin health depends on access to water for regular immersion and the maintenance of skin secretion function — dry environments cause skin cracking and secondary infection. As nocturnal animals, pygmy hippos are naturally inactive during daytime visitor hours — nocturnal house access allows expression of natural activity patterns. They are solitary and may not tolerate conspecifics outside mating introductions — housing must allow visual and physical separation. Their conservation status means every individual and breeding opportunity is significant — veterinary expertise in reproductive monitoring is essential. Genetic management through AZA and EAZA Species Survival Plans coordinates global pairings. Zoos holding pygmy hippos should actively support West African forest conservation given the existential habitat pressure on wild populations.
