Flying
See also: flying fish and flying and gliding animalsThe transition of predominantly swimming locomotion directly to flight has evolved in a single family of marine fish called Exocoetidae. Flying fish are not true fliers in the sense that they do not execute powered flight. Instead, these species glide directly over the surface of the ocean water without ever flapping their "wings." Flying fish have evolved abnormally large pectoral fins that act as airfoils and provide lift when the fish launches itself out of the water. Additional forward thrust and steering forces are created by dipping the hypocaudal (i.e. bottom) lobe of their caudal fin into the water and vibrating it very quickly, in contrast to diving birds in which these forces are produced by the same locomotor module used for propulsion. Of the 64 extant species of flying fish, only two distinct body plans exist, each of which optimizes two different behaviors.

Famous quotes containing the word flying:
“All those who dwell in the depths find their happiness in being like flying fish for once and playing on the uppermost crests of the waves. What they value most in things is that they have a surface, their epidermalityMsit venia verbo.”
—Friedrich Nietzsche (18441900)
“What the hell is nostalgia doing in a science-fiction film? With the whole universe and all the future to play in, Lucas took his marvelous toys and crawled under the fringed cloth on the parlor table, back into a nice safe hideyhole, along with Flash Gordon and the Cowardly Lion and Luck Skywalker and the Flying Aces and the Hitler Jugend. If theres a message there, I dont think I want to hear it.”
—Ursula K. Le Guin (b. 1929)
“Awake! the land is scattered with light, and see,
Uncanopied sleep is flying from field and tree:”
—Robert Bridges (18441930)
