Orcas are among the most socially complex and cognitively sophisticated marine mammals. Their welfare in both the wild and captivity raises profound questions about what meaningful wellbeing looks like for such intelligent animals.
Wild orca welfare is declining alongside their populations. Food scarcity caused by salmon stock collapse means Southern Resident orcas are often nutritionally stressed — a chronic welfare problem as well as a conservation crisis. Vessel disturbance and underwater noise pollution interfere with the acoustic environment orcas depend on for prey detection and family communication. Captive orca welfare was largely incompatible with their needs — long-lived, wide-ranging animals with complex social structures cannot be adequately maintained in concrete tanks. SeaWorld ended its captive orca breeding program in 2016 following regulatory and public pressure, a significant welfare policy change.
