Male elephant seals undertake extraordinary physiological challenges during breeding season, fasting for months while competing intensely. Understanding their welfare reveals remarkable adaptations.
Elephant seal welfare during breeding season involves extreme physiological demands that are naturally adapted but nonetheless represent genuine stress. Breeding males enter hypercatabolism, living entirely on stored blubber while maintaining intense competitive behavior. Combat injuries cause wounds that must heal while fasting continues. Pup crushing by inattentive adults is a natural but preventable welfare harm at colonies where human disturbance increases adult movement. At beaches with high human disturbance, pup mortality from crushing increases. Minimizing visitor disturbance at breeding colonies has measurable welfare benefits.
