A flying fish does not fly, in the sense of flapping its wing-sized fins, but actually glides. Upon breaking the surface, the fish spreads its enlarged fins and gains additional thrust from rapid beats of the still-submerged tail. When sufficient speed has been attained, the tail is lifted clear of the water and the fish is airborne, gliding a few feet above the surface at a speed of about 16 km/h (10 miles per hour). The fish can make several consecutive glides, the tail propelling it up again each time it sinks back to the surface. fish tail
