Flying fish live in all of the oceans, particularly in warm tropical and subtropical waters. Their most striking feature is their pectoral fins,[1][2] by leaping out of the water, taking short gliding flights through air just above the water's surface. Their glides are typically around 50 metres (160 ft).[3] which are unusually large, and enable the fish to hide and escape from predators

Flying fish taking off


In order to glide upward out of the water, a flying fish moves its tail up to 70 times per second.[4] It then spreads its pectoral fins and tilts them slightly upward to provide lift.[1]
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.[1][4]
The curved profile of the "wing" has an aerodynamic shape that is comparable to that of a bird wing.[5] 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.[1][4]
Genus Exocoetus has one pair of fins and a streamlined body to optimize for speed, while Cypselurus has a flattened body and two pairs of fins which maximizes its time in the air.
