Humpback whales are easy to identify and are well known for their spectacular breaching and beautiful, complex songs.
Humpback whales have a small dorsal fin with a distinctive hump at the front, knobbly protuberances on the head, tip of lower jaw and leading edge of extremely long flippers.
Their tail flukes are broad and have a unique black and white colour pattern, which allow individuals to be identified. They have a variable colour but are generally black with white on the underside and on the flippers.
