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 ... Learn about flying fish, ray-finned fish that can glide out of the water at high speeds.
