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:
“Bonnie Lee: Oh, it’s the most wonderful thing I’ve ever seen.
Geoff Carter [sarcastically]: Yes, it reminded you of a great big, beautiful bird, didn’t it?
Bonnie: No, it didn’t at all. That’s why it’s so wonderful. It’s really a flying human being.
Geoff: Well, you’re right about one thing. A bird’d have too much sense to fly in that kind of muck.”
—Jules Furthman (1888–1960)
“The essential is to excite the spectators. If that means playing Hamlet on a flying trapeze or in an aquarium, you do it.”
—Orson Welles (1915–1984)
“And more I may not write of, for they that cleave
The waters of sleep can make a chattering tongue
Heavy like stone, their wisdom being half silence.
How shall I name you, immortal, mild, proud shadows?
I only know that all we know comes from you,
And that you come from Eden on flying feet.
”
—William Butler Yeats (1865–1939)
