Flying fish eat plankton and other small prey in warm ocean waters. The flying fish, however, has to worry about how to avoid its many predators.
The best way for the flying fish to avoid its predators is to swim faster than its predators. The flying fish was built with a thin, long and pointed body with large fins that resemble wings. These physical characteristics help the flying fish to leap or "fly" over the water escaping predators. The flying fish can swim as fast as 37 miles under the water and can glide or "fly" as far as 4 feet above the water. The flying fish is a favorite food source of swordfish, mackerel, tuna and marlin as well as other bigger fish.
