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.

“Some things in life are bad
They can really make you mad
Other things just make you swear and curse
When you’re chewing on life’s gristle
Don’t grumble, give a whistle
And this’ll help turn things out for the best ...
And ... always look on the bright side of life.”
—Monty Python’s Flying Circus. Mr. Frisbee III (Eric Idle)
