Female humpback whale calf (Megaptera novaeangliae) playing at the surface by slapping its tail on the water. This calf was the 44th calf I ID-ed in the 2011 season. She had multiple wounds over her body, including this prominent wound on her fluke. I don't know the cause of the wounds, but I believe that the possibility of an attack by false killer whales (Pseudorca crassidens) is high.
