Orca welfare in captivity has been the subject of significant public and scientific debate following revelations about their complex social needs.
Captive orcas in small pools cannot meet their needs for movement, social complexity, or cognitive stimulation. Dorsal fin collapse in virtually all captive males indicates chronic poor welfare. Stereotypic swimming patterns, aggression, and dental damage are widespread. The scientific consensus is that orca welfare cannot be adequately met in captivity given their extreme needs.
