Dolphins, orca, and belugas in captivity face welfare challenges that facilities debate openly, with scientific evidence informing ongoing policy changes worldwide.
The welfare case against keeping cetaceans — particularly orca and dolphins — in captivity is among the strongest in animal welfare science. These highly intelligent, wide-ranging, socially complex animals are profoundly compromised by the spatial, social, and behavioral constraints of tank environments. Stereotypic behaviors, abnormal social dynamics, early mortality, and the now-iconic collapsed dorsal fin of captive orca all reflect chronic welfare deficits. The argument that educational value justifies these harms has weakened as evidence for harm has strengthened and public attitudes have shifted.
