Wild dolphins captured for display or entertainment suffer acute trauma during capture and face lifelong welfare deprivation in captive environments that cannot meet their complex needs.
Dolphins are among the most cognitively complex animals on Earth. They navigate vast ocean ranges with their social groups, communicate through individually distinct signature whistles, cooperate in sophisticated hunting strategies, and transmit learned behaviours across generations. Captive environments cannot provide any of these essentials. The concrete walls of a marine park tank create acoustic nightmares for echolocating animals; the absence of natural social groups prevents normal relationship formation; and the infinite loop of repetitive performances replaces behavioural diversity with monotony. The welfare science literature on captive cetaceans is now extensive and consistently shows chronic stress indicators including elevated cortisol, stereotypic behaviour, and abnormal aggression between tankmates.
