The REAL Flying Fish

Flying fish can remain in the air for up to 45 seconds. How do they do it?

Previous studies found that these fish initially swim extremely fast to gain momentum, then glide on their wing-like fins. When they need more speed during their flight, they beat their tails against the water.

A new investigation found that when the fish fly close to the sea surface, they reduce their drag and maximize their flight efficiency. In fact, apparently their gliding ability "is comparable to those of bird wings such as the hawk, petrel and wood duck."

According to Discovery News:

“Though [researchers] have solved the mystery of how these fish fly, scientists are still unsure why they fly. The leading theory is that it enables them to avoid predators. Another idea is that the combination of flying and swimming is a more efficient mode of transportation that saves the fish energy.”
