Porpoising
Definition
Porpoising is a swimming technique in which penguins leap out of the water in shallow arcs while travelling at high speed, resembling the motion of dolphins or porpoises. The behaviour reduces drag because air offers far less resistance than water, and it allows penguins to breathe without slowing down. Porpoising is common when penguins commute between colony and feeding grounds or when fleeing predators. Gentoo penguins, the fastest swimmers among penguins, are frequently observed porpoising at speeds above 30 km/h.
