Where the name comes from

Megaptera is Greek for “great wings”, from méga, large, and pterón, wing: the outsized pectoral fins, a third of the body long. Novaeangliae, “of New England”, where it was described. In English it is the humpback, for the way it arches its back as it dives.

What sets it apart

Humpback song is a fashion that travels: every male in a population sings the same tune in a given year, but the song changes from season to season, and new versions spread from one ocean to another like a hit record. A phrase born off Australia can turn up months later in Polynesian waters. It is one of the rare animal “cultures” that spreads on a planetary scale.
