A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of head. It blows a double stream of water that can rise up to 4 meters above the water.
The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back. Other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black and white spots on the underside of the tail flukes. These markings are like fingerprints: no two are the same.
