Narwhals are iconic Arctic whales with extraordinary diving abilities that face increasing welfare and conservation threats from sea ice loss and industrial activity.
Narwhals face welfare challenges that are largely invisible to most observers because they live in remote Arctic environments. Capture for research or accidental entanglement causes acute stress responses — narwhals have very strong fear responses and experience severe cardiac stress when restrained. Industrial shipping noise in their feeding grounds causes behavioral disruption that affects feeding efficiency and may contribute to chronic stress. As sea ice retreats, narwhals lose the predictable breathing hole access they depend on, increasing mortality risk. Killer whale predation, while natural, has intensified as orcas expand their range into narwhal territories previously protected by sea ice.
