Flying fish are able to launch themselves above the surface of the water to escape from predators. They support themselves in the air with large, outstretched fins. It is this which gives the appearance of flight.
The lower lobe of a flying fish’s tail is extended so the fish can still propel itself along by beating it in the water while its body is above the surface. A single ‘flight’ above the water can cover a distance of 150 m, at a speed of 55 km/h.
