Keeping orcas in marine parks causes profound physical and psychological suffering, as demonstrated by dramatically reduced lifespans, collapsed dorsal fins, and abnormal behaviors.
The captive orca welfare case is among the most thoroughly documented in animal science. Wild orcas navigate hundreds of miles daily, maintain complex multigenerational social bonds, and live in acoustically rich environments. In concrete tanks, they cannot exercise meaningfully, form stable social bonds, or use their sophisticated echolocation. The behavioral and health consequences — stereotypies, aggression, shortened lifespans, dental damage from chewing tank walls — are severe and consistent across facilities worldwide. No captive environment can adequately meet orca welfare needs.
