Humpback whale. Humpback whale (Megaptera novaeangliae) breaching. Humpback whales are known for these jumps,as well as for their complex vocalisations. It is thought that breaching may be a form of communication,especially in rough seas when vocalisations are not audible. This baleen whale has up to 350 large baleen plates,formed from bristles,hanging down from its jaws. It feeds by swallowing sea water and then pressing its tongue against the bristles,pushing the water out and trapping krill and fish. Fully grown,a humpback whale weighs around 27 tonnes and can reach 15 metres in length. They are found in deep water near coasts in all of the world's oceans | |
