The keeping of dolphins and orcas in marine theme parks and swim-with-dolphin programs has been one of the most contested animal welfare issues of the past three decades, with growing scientific consensus that captive conditions fundamentally compromise cetacean welfare.
The evidence that captivity fundamentally compromises dolphin and orca welfare has become increasingly difficult to dispute. These are cognitively sophisticated, socially complex, wide-ranging animals whose entire behavioral repertoire — echolocating over vast distances, complex hunting cooperation, multi-generational social bonds — cannot be expressed in a tank. The behavioral abnormalities observed in captive cetaceans (stereotypic swimming patterns, abnormal aggression, gastric disease) are the visible expression of chronic deprivation. The entertainment value these animals provide to human audiences comes at a cost of profound, ongoing suffering for the individual animals involved. The alternative — wild cetacean watching from non-intrusive platforms — provides similar public engagement without comparable welfare costs.
