Whales and dolphins in captivity face severe welfare challenges linked to their complex social behavior, intelligence and ocean-adapted physiology.
Cetacean captivity welfare is perhaps the clearest case where scientific evidence and ethical consensus have converged on a strong conclusion: the welfare needs of highly intelligent, wide-ranging, socially complex marine mammals cannot be adequately met in captivity. The evidence is compelling - collapsed dorsal fins as a physical indicator of physiological stress, stereotypic behaviors indicating psychological suffering, dramatically shortened lifespans, and high levels of aggression between incompatible animals forced into proximity. The scientific and welfare arguments that led the UK to ban cetacean captivity for entertainment apply across the species - dolphins, belugas and pilot whales face the same fundamental mismatch between their behavioral needs and the captive environment. Transitioning captive cetaceans to sea pen sanctuaries offers the most welfare-positive available solution.
