North Atlantic right whales number fewer than 350 individuals and face extinction from entanglement in fishing rope and vessel strikes. Each entanglement event causes chronic suffering that may last months to years before death or disentanglement.
Right whales dragging entangled fishing rope experience prolonged suffering over months as rope cuts progressively deeper into blubber and muscle. Chronic infection sets in at rope contact points. Exhaustion from fighting drag reduces feeding efficiency, causing progressive emaciation. Disentanglement by trained teams requires close boat approach and specialised cutting equipment, which can itself cause additional stress. Each suffering individual represents over 0.3% of the remaining population.
