A humpback whale (Megaptera novaeangliae) singing, Hawaii. This was shot under research permit as part of the research activities of the Hawaii Whale Research Foundation. It is virtually certain that only male humpback whales sing since genetic sampling of singers has never revealed a female. This one was hanging motionless 40′ under the surface for the duration of the 15 minute song. The same song is sung by all humpback whales in the North Pacific basin in a given year, gradually changing from year to year. A few remaining barnacles from cold northern waters are visible on the right tip of the fluke and around the genital slit on the whale’s underside; these barnacles will die and fall off the warmer Hawaiian waters.
