Sea lions in zoos require carefully designed aquatic environments and social management to express natural behaviors and maintain good physical and psychological health.
Sea lions in zoos can thrive when enclosures provide sufficient water volume, depth, and complexity to support natural swimming and diving behaviors. Problems arise when pools are too shallow, too warm, or too small, limiting exercise and creating boredom. Social management is critical as sea lions need conspecific company but can also be injured by dominant individuals. Best-practice facilities use positive reinforcement training extensively, enabling voluntary health checks and reducing capture-related stress dramatically.
