Broad head with a series of knobs on top, extremely long white flippers, small dorsal fin, tail with scalloped rather than smooth rear edge. Distinctive behaviour with high leaps, often mid-air rolls, then crashing back into the water on back. Feed in Antarctica during spring, summer and autumn months, then migrate to subtropical and tropical grounds for winter calving, a period when they do not feed. Humpback whales communicate using complex songs, which can travel hundreds of kilometres underwater.
