Northern elephant seals engage in intense male combat during breeding season that causes severe injuries, while climate change and entanglement in fishing gear create additional welfare pressures.
Elephant seal biology involves intense physiological and behavioral demands that sit at the edge of what bodies can sustain. Males competing for reproduction face severe combat injuries with no access to veterinary care. Females nursing pups while fasting experience extreme metabolic stress. These are natural conditions shaped by evolution, raising complex questions about the welfare significance of natural suffering. However, human-caused welfare impacts — entanglement in ghost fishing gear, ingestion of marine debris, and prey depletion from climate change — represent preventable harms layered on already demanding lives.
