Giant tortoises are among the world's longest-lived animals, creating unique welfare responsibilities across potentially century-long lifespans.
Giant tortoise welfare requires thinking across timescales unusual for any other captive species. Decisions made today about housing design, diet, and management may affect individual animals for the next century. The success of Galapagos tortoise captive breeding programs demonstrates that ex-situ management can serve critical conservation functions while maintaining good individual welfare. Key welfare requirements include adequate space for natural movement, appropriate UV exposure, high-fiber dietary management, and social complexity appropriate to the species. The extraordinary longevity of giant tortoises means institutional knowledge about individual animals must be carefully preserved across institutional generations.
