Dolphin Captivity: Welfare Evidence

Bottlenose dolphins in captivity show significant welfare challenges related to space restriction, social disruption, and acoustic stress.

Key Facts

Wild dolphins range over 100 km daily in complex social groups
Captive pools offer a fraction of 1% of wild ranging area
Stereotypic behaviors including glass-surfing and regurgitation-and-reingestion are common
Dolphin shows require conditioning that may interfere with natural behavior

Welfare Considerations

Pool acoustics amplify sonar clicks to damaging levels. Socially complex dolphins experience captive group instability differently from terrestrial species — they cannot retreat or disperse from incompatible individuals. Learned helplessness rather than genuine health is often interpreted as positive welfare by facility visitors.

What You Can Do

Avoid dolphinaria and swim-with-dolphin experiences
Support legislation to phase out cetacean captivity in favor of sanctuaries
Educate others about the welfare evidence behind captive cetacean facilities
Donate to organizations advocating for ocean sanctuary retirements
