Flying Fish Exocoetidae

Exocoetidae, usually called Flying Fish, is a family of fishes aptly named for their ability to emerge out of the water and fly for long distances with their outstretched pectoral fins. Asian countries, like China, Vietnam, and Japan commercially fished flying fish. including the Caribbean where it’s a coveted flimsiness. In many Japanese cuisine, the flying fish is used to make some sort of sushi. It is also a used in the diet of the Tao people of Taiwan. In Barbados, flying fish were heavily threatened by pollution and overfishing, and changing the occurrences of flying fish in the waters off of Barbados. This sparked a fishing controversy between Barbados, and Trinidad and Tobago maneuverability. These fishes are known as four-winged flying fish.Flying fish are thought to have evolved this extraordinary gliding ability to get away predators, of which they have many. Their pursuers include mackerel, tuna, swordfish, marlin, and other larger fish. unluckily, this elusive maneuver is not enough to escape the biggest predator on earth humans.
Their streamlined torpedo shape assist them gather enough underwater speed to break the surface, and their large, wing-like fins get them airborne. Once in the air, these fishes can glide over considerable distances. Their flights are naturally around 50 meters, but some fishes have been recorded to fly up to 200 meters or even more. Some species of flying fish have enlarged pelvic fins as well as enlarged pectoral fins, which let them to fly further than two winged gliders up to 400 meters, and have far greater 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 to some extent upward to provide lift. At the end of a glide, it folds its pectoral fins to reenter the sea, or fall 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 recognized to take advantage of updrafts created by air currents to boost its time of flight.
