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.

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.
