Humpback whales frequently become entangled in fishing gear, causing prolonged suffering and death — a welfare emergency requiring both emergency response and systemic gear reform.
Entangled humpback whales experience prolonged and severe suffering. Rope cutting into flesh around flukes, flippers, or jaws causes progressive lacerations that become infected. Whales dragging heavy gear tire rapidly, making normal feeding impossible and causing starvation over weeks to months. Some entanglements constrict mouth closure, preventing feeding entirely. Drowning from inability to surface occurs when gear wraps around the body. Disentanglement response — when successful — provides immediate welfare relief; cases where teams cut away hundreds of kilograms of gear and watch formerly struggling whales swim freely are among the most impactful individual animal welfare interventions in marine conservation.
