| Humpback whales are among the best-studied cetaceans, yet they are still among the most mysterious. Among the mysteries are the reasons for their songs and the complex social behaviors that accompany them. These songs are intricate, with up to nine musical themes. Males may sing for days, changing themes over time, yet all the males from one population will sing the same song. Humpbacks are popular subjects for ecotourism and the whale-watching business. They are easily identified by enormous, wing-like flippers, which are far longer than in any other whale. They are known for spectacular displays at the surface. They breach, leaping headfirst out of the water; slap the surface with a long flipper; or slam the tail flukes repeatedly. Humpbacks may be the only whales to trap or herd prey into a bunch to make feeding more efficient. They concentrate a school of fish into a stack by blowing columns of bubbles to form a circle around it, and then lunge into the mass to feed. Although endangered, humpback whale populations are making a good comeback.
Females are usually about one meter longer than males.
