Flying fish can see very well outside of water and many probably have not thought about this but it does make sense because there is 750 times less dense than water. If fish can see underwater through the density and murkiness then they ought to be a will see pretty good outside of water except maybe the sun glare in their eyes.

Nevertheless on an overcast day flying fish when they jump out of water would be able to see very well. It has also been noted that flying fish often will glide to make sure they land on the declining side of an ocean wave rather than crashing into the front of the wave. This makes sense because it would be a softer landing for them. But how are they able to do this?

Well, flying fish use their fins as wings to glide and they can steer with them just like they would in the water to maneuver themselves where they wish to land. Yet they would not be able to know where they wish to land unless they had very good eyesight. So therefore flying fish have good eyesight outside of the water and this is an interesting point and that when you have a cross between a bird in a fish, you have something of a hybrid species.

Many evolutionary biologists believe that all life came from the sea and perhaps the fish had good enough eyes to see what was on the land and decided to stay there more often. Please consider all this in 2006.
