Flying fish have forked tails. The lower lobe of the tail is much longer than the upper. As their glide slows and they drop closer to the water's surface an amazing thing happens. Rather than splash back into the water, they may vibrate their lower tail lobe in the water to pick up speed and extend their flight! Thus, a fish may combine several glides into a single flight reaching several hundred feet! They may stay out of the water for more than 30 seconds.
Up to 19 inches long--California Flying Fish are the world's largest.
