To prepare for flight, flying fish gain great speed underwater. Once they break the surface, the fish taxi their tails and extend their "wings," which are pectoral fins, to glide. This behavior is a method of escaping predators. Some species of flying fish are called four-winged flying fish, because their pelvic fins look wing-like as well.
