Flying fish, any of about 40 species of oceanic fishes of the family Exocoetidae (order Atheriniformes), found worldwide in warm waters and noted for their ability to fly. Flying fish are known for their distinctive, wing-like pectoral fins. These fins are not just for show; they are instrumental in enabling their gliding flights over the water surface. When in motion, the fins spread wide, acting like wings. This adaptation is crucial for escaping predators. Flying fish are marine fish that can leap out of the water and glide through the air using their wing-like pectoral fins. Learn about their description, distribution, diet, behavior, life cycle, and interesting facts with pictures and references. Flying fish have large pectoral fins almost as long as the body which serve as wings, helping the fish glide through the air when it leaves the water. The pectoral fin expands and stiffens while in the air for a short distance before the fish reenters the water. A flying fish can remain airborne for at least 30 seconds and can reach a top speed of at least 40 MPH (64 km/h) produced by the rapid movement and vibration of the tail. The tail is the first part of the fish to reenter the water ...
