North Pacific humpback whale showing extensive scarring, almost certainly from a boat propeller, on dorsal ridge. This female North Pacific humpback whale was first seen with the depicted lacerations near the island of Maui in the Hawaiian Islands in the mid-90s, and is the original humpback to bear the name 'Blade Runner'. This female has apparently recovered, as evidenced the calf she was observed nurturing. A South Pacific humpback whale endured a similar injury in Sydney Australia in 2001, and bears a remarkably similar scar pattern to the above-pictured whale.
