Sea lions are intelligent, social pinnipeds found in zoo and aquarium collections worldwide. Their welfare in captive settings depends on meeting complex social, cognitive, and aquatic behavioral needs.
Sea lion welfare in captivity is shaped by their high intelligence and social complexity. These animals are curious, playful, and engage readily with training and enrichment when properly managed. Facilities that provide enriched aquatic environments, complex foraging challenges, compatible social groups, and voluntary veterinary care through positive reinforcement training can achieve genuinely good welfare outcomes. Facilities that use sea lions primarily for entertainment performances, house solitary individuals, or provide inadequate aquatic environments fail to meet welfare needs. The shift in public expectation from performance-based to education-based marine mammal experiences has driven significant welfare improvement in this sector, though progress continues to be needed in many facilities globally.
