The welfare of dolphins, orcas, belugas, and other cetaceans in captivity is one of the most contentious areas of animal welfare debate, with scientific evidence of compromised wellbeing clashing with industry claims about conservation and education.
The welfare evidence against keeping large cetaceans in captivity is now substantial and widely accepted among marine biologists and welfare scientists. These highly intelligent, wide-ranging, acoustically sophisticated animals cannot be meaningfully provided with the environmental complexity, social structures, and space they need in any tank environment. The industry argument that captivity serves conservation is undermined by the fact that most captive cetacean species are not endangered and captive breeding does not support wild population recovery. Welfare-based restrictions on cetacean captivity represent evidence-based policy grounded in decades of scientific observation.
