	HUMPBACK WHALE
		Humpbacks are acrobats of the ocean, breaching and slapping the water.
		Humpback whales (like all baleen whales) are seasonal feeders and carnivores that filter feed tiny crustaceans (krill - mainly Euphausia superba, copepods, etc.), plankton, and small fish (including herring, mackerel, capelin, and sandeel) from the water.
		Humpback whales (Megaptera novaeangliae) are baleen whales (Suborder Mysticeti).

	Humpbacks
		Humpback whales are widely distributed over all the oceans from the poles to the topics, but there are distinct seasonal changes in their distribution.
		Humpbacks spend much of the year close to continental shores or oceanic islands (another reason why they are a favourite with whale watchers), where they breed and feed on shallow banks or continental slopes, but they migrate across the open ocean.
		Humpbacks are reasonably slow swimmers, they can move at 6-12km per hour but during their migratory swims they rest and socialize frequently and swim at an average of about 1.6km (1 mile) per hour.

	Humpback Whales in Hawaii pictures, behaviors
		Humpback whales (na kohola) are found in all of the world's oceans, although they generally prefer near shore and near-island habitats for both feeding and breeding.
		The humpback's pectoral fin is longer than that of all other species of whales, measuring one-third the whale's body length, or approximately twelve to fifteen feet.
		Humpbacks will often roll onto their side or back and slowly slap the water's surface with one fin or both fins simultaneously.

	The Marine Mammal Center
		Humpbacks are gray or fl, except for the flippers, parts of the chest and belly, and sometimes the underside of the tail flukes.
		Unique to humpbacks are wartlike round protuberances (bumps or tubricales) that occur on the head forward of the blowhole and on the edges of the flippers.
		Humpbacks are best known for their haunting vocalizations or "singing." They have a rich repertoire that covers many octaves and includes frequencies beyond the threshold of human hearing.

		Humpbacks do not have functional vocal cords; evidence suggests that their sounds are produced by valves and muscles in a series of blind sacs which branch off in the respiratory tract.
		Humpbacks are easily observed from land, sea or air because of their tendency to congregate close to shore.
		Humpback whales are still threatened by commercial whaling, as well as commercial and acoustic pollution, marine debris, destructive fishing practices and the loss of habitat through human encroachment.

		Humpbacks are also one of the world's best singers: not even the most operatic nightingale can compete with the complexity or length of their song.
		The humpbacks that migrate to Colombia have the longest journey of all, some 8000 kilometers, and are the only population to cross the Equator during their migration.
		Their hope is that the humpback whales, migratory birds, and marine turtles will continue to be welcome guests in Colombia and made to feel at home, while their hosts benefit too from their visit.

	Humpback Whale (Megaptera novaeangliae) (Site not responding. Last check: 2007-10-23)
		As with other balaenopterid whales, humpbacks have a dorsal fin, which may be up to 31 cm in height, and is falcate to rounded in profile.
		Other differences of the humpback whale include lack of a median head ridge, enormous flippers, and the presence of numerous knobby structures, or "dermal tubercles," about the dorsal surface of the snout, chin, and mandible.
		Humpbacks commonly slap their tail flukes or flippers on the water’s surface and occasionally lift their huge heads above water to peer about, a behavior known as "spyhopping." Tail slapping, breaching, and other such behaviors may serve in communication between the whales, possibly as warnings or a means of indicating location.
