Humpback whales are one of conservation's great success stories, recovering from near-extinction after commercial whaling — but today they face new threats from ship strikes, entanglement, and ocean noise that cause suffering at scale.
The welfare of humpback whales — and large whales generally — is defined by the nature of their deaths and the suffering they endure before death. Entanglement causes some of the most prolonged and severe welfare harms documented in marine mammals: whales documented dragging gear for weeks or months before disentanglement or death, with wounds, emaciation, and exhaustion accumulating throughout. Ship strike deaths may be rapid, but strikes that cause sublethal injury leave animals with broken bones or propeller wounds. Ocean noise creates a chronic stressor that interferes with the communication and echolocation central to whale social and foraging life. The welfare and conservation imperatives here are aligned — reducing entanglement, ship strikes, and noise benefits individual whales and population recovery simultaneously.
