Overview

The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is one of the larger rorqual species, with adults ranging in length from 12–16 m (39–52 ft) and weighing around 25–30 t (28–33 short tons). The humpback has a distinctive body shape, with long pectoral fins and a knobbly head. It is known for breaching and other distinctive surface behaviors, making it popular with wh…

Taxonomy

The humpback was first identified as baleine de la Nouvelle Angleterre by Mathurin Jacques Brisson in his Regnum Animale of 1756. In 1781, Georg Heinrich Borowski described the species, converting Brisson's name to its Latin equivalent, Balaena novaeangliae. In 1804, Lacépède shifted the humpback from the family Balaenidae, renaming it B. jubartes. In 1846, John Edward Gray created the genus Megaptera, classifying the humpback as Megaptera longipinna, but in 1932, R…

The humpback whale is perhaps the most recognizable baleen whale. It has a highly narrow rostrum, robust body and proportionally long flippers (around one-third its body length). The dorsal fin is generally small but varies in shape from low and almost non-existent to relatively high and curved. Rounded bumps or tuberclesexist on the upper and lower jaw and front edge of the flippers, while …

Behavior and ecology

Humpback whales can be highly active at the surface, performing aerial behaviors such as breaching, tail slapping (lobtailing) and flipper slapping. These may serve various functions such as play, communication, parasite removal, and displaying excitement or annoyance. Humpbacks rest at the surface in a horizontal position. They are observed to interact with other cetac…

Range and habitat

Humpbacks inhabit all major oceans, in a wide band running from the Antarctic ice edge to 81°N latitude. The four global populations are North Pacific, Atlantic, Southern Ocean and Indian Ocean populations. These populations are distinct. Although the species has cosmopolitan distribution and is usually not considered to cross the equator line, seasonal observations at Cape Verdesug…

Relation to humans

Humpback whales were hunted as early as the 18th century. By the 19th century, many nations (particularly the United States) were hunting the animal heavily in the Atlantic Ocean and to a lesser extent in the Indian and Pacific Oceans. The late-19th-century introduction of the explosive harpoon allowed whalers to accelerate their take. This, along with hunting in the Antarctic Oceanbeginning …

Status

The worldwide population is estimated at 84,000 and increasing. Regional estimates are 18,000–20,000 in the North Pacific, 12,000 in the North Atlantic and over 50,000 in the Southern Hemisphere, down from a prewhaling population of 125,000.
