Flying fish look very strange, and their pectoral fins are particularly developed, like the wings of a bird. The long pectoral fin extends all the way to the tail, and the whole body is like a "long woven". Flying fish can move at a high speed of 10 meter per second in the sea with its streamlined and graceful posture. It can jump out of the water for more than ten meters, stay in the air for more than 40 seconds, and fly for more than 400 meters. Flying fish's back color is close to seawater, and they often move on the surface of seawater. Often flying in groups at sea, shaped like carp and bird-winged fish, with white lipstick on the head and blue texture on the back, often flying at night.

Flying fish accelerate underwater, and when they swim to the surface, their fins cling to the streamlined body. As soon as the water breaks, open the big fin and flap the tail that is still in the water quickly, thus gaining extra thrust. When the strength is enough, the tail is completely out of the water, so it flies and glides a few feet above the water at the speed of 16 km (10 mile) per hour. Flying fish can glide continuously, and every time they fall back into the water, their tails push their bodies up again. Stronger flying fish can glide as far as 180 meters (600 feet) at a time, and the distance of continuous gliding (up to 43 seconds) can reach as far as 400 meters (1300 feet).
