Flying fish(Parexocoetus brachypterus). Any of various marine fishes of the family Exocoetidae, having enlarged, winglike pectoral fins capable of sustaining them in brief, gliding flight over the water.
Flying fish, common name for members of the Exocoetidae, a family of carnivorous or herbivorous fish of warmer seas. Flying fishes usually swim in schools. They average 7 to 12 in. (17.5-30 cm) in length and have pectoral fins that compare in size with the wings of birds; in some species the pelvic fins also are enlarged. Of the latter type, best known in Atlantic waters are the four-winged flying fish and the bearded flying fish, named for the long barbels around the mouths of the young. The young of many species of flying fishes resemble blossoms of the plant Baringtonia and are thus protected from predators. The California flying fish (Cypselurus californicus), the largest (up to 18 in./45 cm) of the family, is common in the Pacific; the black-winged flying fish is found in both oceans. Flying fishes generally do not actually fly, but glide on their outstretched fins for distances of up to 1/4 mi (0.4 km). Their velocity (up to 30 mi/48 km per hour) builds as they approach the water's surface until they launch themselves into the air, vibrating their specially adapted tail fins in order to taxi along the surface. Flying fishes are excellent food; their aerial talents help them to avoid the tuna, mackerel, and dolphins that prey on them. Flying fishes are classified in the phylum Chordata, subphylum Vertebrata, class Osteichthyes, order Beloniformes, family Exocoetidae.

Sailfin flying fish "Barongoy". Flying fish family has 64 species grouped in seven to nine genera. Flying fish live in all of the oceans, particularly in tropical and warm subtropical waters. Their most striking feature is their pectoral fins, which are unusually large, and enable the fish to hide and escape from predators by leaping out of the water, taking short gliding flights through air just above the water's surface. Their glides are typically around 50 meters (160 ft).
To glide upward out of the water, a flying fish moves its tail up to 70 times per second. It then spreads its pectoral fins and tilts them slightly upward to provide lift. At the end of a glide, it folds its pectoral fins to reenter the sea, or drops its tail into the water to push against the water to lift itself for another glide, possibly changing direction. The curved profile of the "wing" is comparable to the aerodynamic shape of a bird wing. The fish is able to increase its time in the air by flying straight into or at an angle to the direction of updrafts created by a combination of air and ocean currents.

 

Flight measurements

The creature can spent 45 seconds in flight. Flying fish can use updrafts at the leading edge of waves to cover distances of at least 400 m (1,300 ft). They can travel at speeds of more than 70 kilometers per hour (43 mph). Maximum altitude is 6 m (20 ft) above the surface of the sea. Some accounts have them landing on ships' decks.
