Distribution and Description
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 and flying through air a few feet above the water's surface. Their flights 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.
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. From 1900 to the 1930s, flying fish were studied as possible models used to develop airplanes.
Exocoetidae feed mainly on plankton. Predators include dolphins, tuna, marlin, birds, squids and porpoises.

Famous quotes containing the words distribution and/or description:
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
