Flying fish can be seen jumping out of warm ocean waters worldwide.
Their streamlined torpedo shape helps them gather enough underwater speed to
break the surface, and their large, wing-like pectoral fins get them airborne. Flying
fish are thought to have evolved this remarkable gliding ability to escape
predators, of which they have many. Their pursuers include mackerel, tuna,
swordfish, marlin, and other larger fish. For their sustenance, flying fish
feed on a variety of foods, including plankton.
There are about 40 known species of flying fish. Beyond their useful
pectoral fins, all have unevenly forked tails, with the lower lobe longer than
the upper lobe. Many species have enlarged pelvic fins as well and are known as
four-winged flying fish.
A
streamlined torpedo shape helps flying fish generate enough speed to break the
water’s surface, and large, wing-like pectoral fins help get them airborne.
The process of taking flight, or gliding, begins by gaining great
velocity underwater, about 37 miles (60 kilometers) per hour. Angling upward,
the four-winged flying fish breaks the surface and begins to taxi by rapidly
beating its tail while it is still beneath the surface. It then takes to the
air, sometimes reaching heights over 4 feet (1.2 meters) and gliding long
distances, up to 655 feet (200 meters). Once it nears the surface again, it can
flap its tail and taxi without fully returning to the water. Capable of
continuing its flight in such a manner, flying fish have been recorded
stretching out their flights with consecutive glides spanning distances up to
1,312 feet (400 meters).
Flying fish are attracted to light, like a number of sea creatures, and
fishermen take advantage of this with substantial results. Canoes, filled with
enough water to sustain fish, but not enough to allow them to propel themselves
out, are affixed with a luring light at night to capture flying fish by the
dozens. There is currently no protection status on these animals.
