A blue whale eating krill. This blue whale is seen feeding and surfacing amid krill with its throat fully engorged with krill and water. It will push the water back out with its tongue, trapping the krill in its baleen which acts like a filter. Aerial photo, Baja California, Balaenoptera musculus
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, Megaptera novaeangliae
