Humpback whales were heavily targeted by commercial whaling in the north Pacific until ; by the end of this harvest, there may have been as few as humpbacks left. The north Pacific population of humpback whales makes long distance migrations. They range from winter breeding grounds in southern latitudes Hawaii, Mexico, and Southern Asia to northern feeding areas from California to Alaska and Russia where they spend the summer months. Humpbacks show great fidelity to their feeding areas and British Columbia is split into two separate regions.
Below the mouth are 12 to 36 throat grooves that expand to hold the water. Choose a Hkmp. Most populations undertake huge annual migrations, moving Hup mating and calving grounds in warmer, tropical waters, and feeding grounds in colder, more bountiful waters. Populations have recovered, to between 30, and 40, which is about 30 to 35 percent of the population inaccording to the American Cetacean Society. Some say the humpbacks were showing signs of mourning; others say the whales were simply curious or confused.

The Humpback Whale is one of the most recognized of them all due to the hump over the dorsal fin. They have an average size of 52 feet long. There is quite a difference in their sizes depending on location when it comes to weight. Those that live in cooler regions can be up to 40 tons whiles those in the tropical areas are about 30 tons.
They have a very long tail that can be up to a third of body length. They also have huge flippers that are often referred to as wings do to the position of them as they leap out of the water.

They tend to do plenty of great moves and flips in the air effortlessly as they rise to the surface for air.

This gives the appearance that they are very curious about their surroundings.
The Humpback Whale is very social, and sings louder than most of the others out there. They form very small but intimate groups.
They tend to stay within the same groups for most of their lives too. The Humpback Whale has a more detailed feeding system than any other whale out there.
They feature grooves on the throat that allow it to open up and to expand when they eat. This way they can take in huge amounts of water. The filtering system keeps the food and pushes the water out. They are seasonal feeders and then they cut down to almost nothing when they migrate. They have a very detailed system within their pod to help them with hunting for food. This is called bubble net feeding and is interesting to watch. They create a circle under the water with their bodies and then blow bubbles.
The bubbles are able to trap the small sea life that they would like to consume. This mass of prey will rise up and then the Humpback Whales can eat it with ease. You will generally find Humpback Whales at the surface of the ocean waters. They migrate a very long distance and since they move very slow it takes them a while to complete the process. Even though they move slowly, they do move steadily towards their destination with almost no time to stop and rest.

Humpback whale , Megaptera novaeangliae , a baleen whale known for its elaborate courtship songs and displays. Humpbacks usually range from 12 to 16 metres 39 to 52 feet in length and weigh approximately 36 metric tons 40 short [U.
The body is black on the upper surface, with a variable amount of white below, and it has about 30 broad ventral grooves on the throat and chest. This cetacean is distinguished from other baleen whales by its long, narrow flippers, which are about a third as long as the body and scalloped on the forward edge. Humpbacks also have large knobs on the head, jaws, and body, each knob being associated with one or two hairs.
The dorsal fin is small and set far back on the body. Humpback whales live along the coasts of all oceans, occasionally swimming close to shore, even into harbours and rivers. They undertake long migrations between polar feeding grounds in summer and tropical or subtropical breeding grounds in winter.
Diet consists of shrimplike crustaceans called krill , small fish , and plankton, which the humpback whale strains out of the water with its baleen. Humpbacks use a unique method of feeding called bubblenetting, in which bubbles are exhaled as the whale swims in a spiral below a patch of water dense with food. The curtain of bubbles confines the prey to a small area in the middle of which one or more whales surface.
The most vocal of all whales, humpbacks make a great variety of sounds, from moans and cries to groans and snores. The songs vary among groups of whales in different regions and undergo gradual but distinctive changes from year to year.
The humpback is also one of the most acrobatic cetaceans. It frequently breaches by leaping belly-up completely clear of the water, then arching backward and returning to the surface with a loud slapping sound. When beginning a deep dive, the animal hunches its back and rolls steeply forward, bringing its tail out of the water and perpendicular to the ocean surface. The humpback whale was at one time commercially valuable and was greatly reduced in numbers by overhunting in the early and midth century.
It has been protected worldwide from commercial whaling since the mids, and many populations have increased. These population increases have prompted the International Union for Conservation of Nature IUCN to change the status of the humpback whale from endangered to vulnerable.
Although the humpback is the only species in the genus Megaptera , it is related to other rorquals of the family Balaenopteridae, including the blue whale , fin whale , and sei whale. Humpback whale.
