The narwhal is one of the most Arctic-adapted and least-studied cetaceans, facing accelerating threats from sea ice loss, increased shipping, and oil exploration that disrupt feeding and social behaviour.
Narwhal welfare is shaped by the pace of Arctic change. Their extreme adaptation to sea ice environments means that change happening at current rates leaves little time for behavioural adjustment. Killer whale predation, previously blocked by ice, is increasing as sea lanes open. Shipping noise disrupts the acoustic communication and navigation on which narwhals depend in low-light Arctic environments. Entanglement in sea ice during sudden freeze events causes drowning. Subsistence hunting, while culturally significant, causes acute suffering at point of kill. Welfare-conscious approaches to subsistence management focus on improving killing methods and minimising suffering during harvest.
