They are not birds, they fly. The only function of the flight is really to protect themselves from predators. They were flying fish. Flying fish belong to the order and the family Belonifomes Exocoetidae Actiniopterygii and class. They are all marine fish. About 9 genera and 64 species are known for flying fish. They live in all oceans, in particular, ranging from temperate to tropical waters. The fish are characterized by the presence of elongated pectoral fins. Thispectoral fins help the fish to escape predators by short glides out of the water still in the air for a while, 'and then back into the water. The fish can glide for a distance of 50 meters. The word derives from a Latin word.
To slide the fish requires an effort out. To slide on the surface of water the fish moves its tail up to 70 times per second, and then expand the pectoral fins, which give a lift to the body and the fishglides in the air, finally. After returning from the crash of the folds of the pectoral fins of fish re-introduce the water and the tail is used for lifting water to change direction. The pectoral fins are mostly in their aerodynamic exterior profile exactly the same as that of a bird's wing. The fish may be its time of flight in the air with the combined action of currents of air and water. The common example is Exocoetus few flying fish pectoral fins are elongatedfins and a streamlined body to maintain a good speed. On the other hand, has two pairs of pectoral fins Cypselurus that help the fish glide in the air for a longer period.
The intensity and the time the fish in the air is variable. It was reported that the fish can be a distance of about 400 meters of coverage and can fly at a speed of 70 km / h. they prefer to feed on plank-ton. The main predators of these fish are dolphins, tuna, squid, birds and porpoises. They are caughtfor commercial purposes in Japan, Vietnam and Barbados with gill nets. They are captured by dip-netting technique in Indonesia and India. Barbados is commonly known as the land of the flying fish. Today are the official state fish. In the current scenario of commercial production of flying fish has increased in other countries and this has led to a series of marine disputes. In Japan, the fish is allowed to dry before being consumed.In Japanese cooking Japanese flying fish roe is used in making a number of species known as Tobiko sushi. In Taiwan, a staple food of people Tao of Orchid Island. Since the year 1930 and 1990 these fish were used as templates for the construction of aircraft.
