Pygmy hippos are rare, secretive West African mammals increasingly found in zoos worldwide. Meeting their complex needs in captivity requires careful habitat design, social management, and behavioral enrichment.
Pygmy hippos in zoos face challenges related to their solitary, nocturnal nature. Exhibits often underestimate their need for dense vegetation, wallowing pools with adequate depth, and separation from other animals at night. Stereotypic pacing can indicate poor habitat complexity. Breeding pairs require careful management as males may injure females. Temperature, humidity, and substrate choice all affect skin health — insufficient moisture leads to cracking. Positive reinforcement training for veterinary procedures (mouth opening, standing on scale) reduces stress during health checks. AZA Species Survival Plans coordinate breeding to maintain genetic diversity among the small captive population.
