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:
“A word carries far—very far—deals destruction through time as the bullets go flying through space.”
—Joseph Conrad (1857–1924)
“He was last seen flying to New York.

He will demand something not on the menu.
He is invisible to the eyes of beauty and culture....””
—John Ashbery (b. 1927)
“When you have shot one bird flying you have shot all birds flying. They are all different and they fly in different ways but the sensation is the same and the last one is as good as the first.”
