Humpback Whales

Short answer: The humpback whale (Megaptera novaeangliae) is a baleen whale known for its songs, which are sung by males. A song is built from repeated themes, usually lasting about 10 to 20 minutes, and males may repeat it for hours.

All males in a population sing roughly the same song, which changes over time. A 2011 study found new songs spreading eastward across South Pacific populations over several years, an example researchers describe as cultural transmission. The footage shows humpback whales swimming and breaching, with the presenter.
