Zoos & Captivity

Zoo Welfare: Marine Mammal Captivity Debate

The welfare of dolphins, orcas, and other marine mammals in captivity is one of the most debated areas of zoo animal welfare, with strong evidence of welfare compromise.

Key Facts

Captive orcas show stereotypic behaviour, collapsed dorsal fins, and reduced lifespan compared to wild populations
Dolphin-assisted therapy claims have limited scientific support and raise serious welfare concerns
Many countries have banned or are phasing out cetacean captivity for entertainment purposes
Genuine marine mammal rehabilitation programmes, with the goal of release, present a different welfare context

Welfare Considerations

The welfare evidence against keeping large cetaceans in captivity for entertainment is compelling. These highly intelligent, wide-ranging species cannot achieve good welfare in even the largest pools. Transitioning from entertainment-focused facilities to sanctuary models is a welfare imperative for currently captive animals.

What You Can Do

Avoid dolphin and orca shows and entertainment venues
Support campaigns for the transition of captive cetaceans to sea sanctuaries
Engage with organisations developing evidence-based marine mammal welfare standards
