Sperm whales make extraordinary dives to find squid in the deep ocean. Their complex social lives and vulnerability to ocean noise pollution present unique welfare considerations.
Sperm whales' deep diving lifestyle creates vulnerability to chronic anthropogenic ocean noise. Their echolocation system is exquisitely sensitive and mid-frequency sonar can cause disorientation and panic, leading to dangerous rapid ascents. Evidence from mass stranding events linked to naval exercises shows whales with gas bubble disease - indicating they surfaced too quickly. The ingestion of plastic debris causes chronic suffering through intestinal blockages that impair digestion and cause malnutrition before death. The strong social bonds of sperm whale groups mean that death or injury to one individual causes disruption across the family unit, with potential behavioral and reproductive consequences for survivors.
