Dolphins in marine parks and aquariums face significant welfare challenges. The debate about captive dolphin welfare has intensified as evidence of their cognitive complexity has grown.
Captive dolphin welfare sits at the center of one of the most contested debates in animal welfare. Dolphins are among the most cognitively sophisticated animals known — with demonstrated self-recognition, language-like communication, cultural transmission, and complex social intelligence. The question of whether highly intelligent, wide-ranging social animals can experience good welfare in pool environments has no consensus answer, but the evidence of abnormal behavior, social disruption, and shortened lifespan in captivity is consistent. The cultural trajectory is clearly toward reduced captivity: many countries are phasing out dolphin entertainment shows, and some are banning captivity entirely. The welfare case for dolphin captivity is weakest for entertainment purposes and strongest (though still contested) for animals that cannot be released to the wild.
