Humpback whale calf swimming toward the surface to take a breath, while its mother (lower) and accompanying escort (upper) swim beneath. This calf is male, and is the 3rd one I ID-ed in the 2011 season in Vava'u, Tonga. The calf has a wound on its lower abdomen that is visible in this photograph. It looks as if it may have been caused by a rope or line of some sort.
