The flying fish, a genus of teleostean fishes belonging to the family Scomberesocidae, of the sub-order Abdominales. The body is whitish, and the belly angular. The pectoral fins, which are very large, are the principal instruments in its flight, but whether they act as wings in propelling it, or merely as parachutes or kites in enabling it to sustain itself in the air, has been a matter of question among naturalists. It is probable that the fins serve to sustain the fish temporarily in the air after it has acquired an initial velocity in its rush through the water. It can raise itself from the water and pass through the air to a considerable distance, sometimes as much as 200 yards, which it does to escape from the attacks of other fishes, especially the dolphin. It is most common between the tropics. The best known species are E. volitans, abundant in the warmer part of the Atlantic, and E. exiliens of the Mediterranean. By some naturalists the genus has been subdivided into several, characterized by the presence or absence of barbels.
