Sea lions and fur seals are popular zoo and aquarium attractions, but meeting their complex behavioral and environmental needs in captivity is challenging.
Sea lions and fur seals in captivity face environmental conditions that often fall far short of their natural behavioral repertoire. Wild pinnipeds swim vast distances, dive to significant depths, hunt live prey, and maintain complex social structures in large colonies. Captive environments cannot replicate this complexity, but welfare-conscious facilities work to provide adequate pool volume, environmental enrichment, complex social groupings, and positive reinforcement training that gives animals agency and cognitive engagement. Performance shows that require unnatural behaviors for entertainment raise welfare questions, while training that gives animals choice and control can actually benefit welfare. BIAZA and AZA accreditation standards provide welfare benchmarks, but enforcement varies. The case for holding sea lions in captivity rests on conservation education and research contributions.
