Organism information awaits expert curation
Taxonomy
Kingdom:Animalia
Phylum:Chordata
Class: Mammalia
Order:Cetartiodactyla
Family:Balaenopteridae

Description
Size: Male: 15 m; Females: 16 m.

Weight: 25-65 tons

Color: Humpback Whales are black or grey in color, with a white region on the throat and belly. The flippers are white underneath, sometimes above as well. There are 270-400 baleen plates on each side, the largest being up to 70 cm long and 30 cm wide. They are black with black or olive-black bristles.

The body of a Humpback Whale is more robust than those of the other rorquals, but the head is slender, and is described as alligator-like in profile. The top of the head is flattened and covered by a number of fleshy knobs. There is a round protuberance at the tip of the lower jaw. When seen from above, the head is broad and rounded. Unlike the other rorquals, the ridge along the midline on top of the head is indistinct. The number of throat grooves is 14-35, extending to the navel. The dorsal fin is located less than one-third of the body length from the tail fluke notch. It may be small and triangular, or larger and sickle-shaped. It frequently includes a step or hump, giving the species its common name. A Humpback Whale’s flippers are very long, measuring about one third of the total body length. They are scalloped with knobs or bumps. The tail flukes are broad and butterfly-shaped, and have some white coloration below. Usually seen in family groups of 3 or 4, Humpback Whales produce a single bushy spout up to 3 m high. Some Humpback Whales have the remnants of hind limbs. Sensory knobs on head.Lifts tail when diving. Variably curved dorsal fin midback on a hump. "Knuckles" or bumps along tail stock of thin whales. Flippers may reach length of 4.5 m (15'). Individuals recognized by underside of flukes and body scars/markings.
It feeds on herring (Clupea harengus), sand lance (Ammodytes sp.) and other small fish, invertebrates (euphausiids).

Some Humpback Whales leap out of water and lobtail prior to feeding. Humpback Whale appears to enjoy breaching, and this type of behavior attracts tourists. A breaching Humpback Whale launches itself gracefully into the air and executes a half-twist so that it lands on its back. Seagulls steal fish from Humpback Whales’ open mouth, but careless birds may be swallowed accidentally. The singing of Humpback Whales at their breeding grounds is now famous. Their songs are audible from far away. These whales do not sing at their feeding grounds, though they do communicate with each other.

Similar species: May be confused with Blue and Sperm Whale from a distance.
Interestingly, the distinctive marks on the undersides of the flukes help in individualizing the species. Such labeling is useful to understand movements and migration.
