Humpback whale (Megaptera novaeangliae) diving into water, seen from underwater. The humpback whale can grow to 27 tonnes in weight and 15 metres in length. It has up to 350 large bristly baleen plates hanging down from its jaws. It feeds by swallowing sea water and then pressing its tongue against the plates, pushing the water out and trapping krill and fish. The humpback whale is found in deep water near coasts in all of the world's oceans. Photographed in the Pacific Ocean, off Rurutu Island in the Austral Archipelago, French Polynesia.
