Captive dolphins in marine parks and aquariums face profound welfare challenges from confinement in environments that cannot replicate the complexity of their natural habitat.
Captive dolphin welfare involves one of the starkest mismatches between natural habitat and captive environment in the zoo world. Dolphins are highly intelligent, socially complex, wide-ranging animals whose behavioral repertoire simply cannot be expressed in concrete tanks. The deprivation is not merely physical — lacking space to travel — but cognitive and social: captive dolphins cannot engage in the complex cooperative hunting, acoustic communication, and dynamic social relationships that characterize wild dolphin life. The welfare case against captive dolphin entertainment is among the strongest in animal advocacy. While some facilities have moved toward sanctuary models that prioritize dolphin welfare over performance, the majority of captive dolphins worldwide remain in conditions incompatible with their needs.
