... the Northern Rightwhale Dolphin loves to “porpoise”? Porpoising is the name given to the actions of dolphins which leap out of the water while swimming forward very fast. These leaps are sometimes quite spectacular; in the case of the Northern Rightwhale Dolphin, leaps of up to 23 feet (7 meters) have been observed. Curiously enough, even though this kind of behavior is called porpoising, porpoises seldom do it.
