Pygmy hippos are critically endangered and poorly understood — their welfare in zoo settings serves a critical conservation function.
Pygmy hippo welfare in captivity carries both conservation significance and genuine welfare challenges rooted in the significant gaps in our understanding of their wild behavioral ecology. Without comprehensive knowledge of their natural behavioral repertoire, developing evidence-based captive welfare standards is genuinely difficult. What is known — their solitary, nocturnal, forest-dwelling nature — suggests that large naturalistic exhibits with dense vegetation, water features, and appropriate night management are important. The conservation value of captive pygmy hippos is real, and this value motivates the investment in welfare that the species requires.
