Dolphins, orcas, and other marine mammals in captivity face fundamental welfare challenges from confined spaces, social disruption, and performance demands. The ethics of marine mammal captivity continues to evolve.
Marine mammals are among the animals most fundamentally incompatible with captivity. Their spatial, social, and behavioral needs cannot be met in any tank environment. Orcas in captivity show behavioral abnormalities, shortened lifespans, and psychological distress markers. The ethical consensus has shifted significantly — new wild captures for entertainment are increasingly banned, and the question of retiring existing captive animals to sea sanctuaries is gaining traction. Consumer refusal to support performance-based marine mammal venues is the most direct individual lever for change.
