A Flying Fish photo in the South China Sea.

There are more flying fish than any other kind of fish, at least that's the way it seemed. 

The flying fish would jump out of the waves sometimes two or three at a time.  They wouldn't really fly by flapping their wings, they would just use the peak of a wave to assist their jump into the air.  The fish would glide for a long way just above the water, then they would fold their wings and swim like a fish.  I bet they thought they were like Jonathan Seagull by trying to see who could stay in the air the longest. 
In this photo, you can see another flying fish just below the water right next to the flying fish in the air.
