Flying fish can make powerful, self-propelled leaps out of water into air, the pectoral fins, which are very large, are the principal instruments in their flight, serving to sustain the fish temporarily in the air after it has acquired an initial velocity in its rush through the water. This uncommon ability is a natural defense mechanism to evade predators.

It can pass through the air to a considerable distance, sometimes as much as 150 to 200 yards, which it does to escape from the attacks of their enemies, or when disturbed by passing vessels. Flying fish live in all of the oceans, particularly in tropical and warm subtropical waters but the best-known species
can pass through the air to a considerable distance
are Exocaetus volilans, abundant in the warmer parts of the Atlantic, Cypsilurus californicus, on the coast of California, and Parexoaetus mesogaster.

Some species of flying fish are used for delicious sea food. They are commercially fished in Japan, Vietnam and China by the method of gillnetting, and in Indonesia and India by dipnetting.
