ปลาบินได้จริงหรือ

ปลาบินหรือปลานกกระจอกจะบินฝ่าขึ้นไปในอากาศได้จริงๆ ถ้ามีศัตรูขับไล่ทำร้ายมัน มันจะรีบว่ายน้ำให้เร็วที่สุด แล้วทะยานตัวขึ้นให้พ้นน้ำ พร้อมกับกางครีบอกที่ใหญ่มากข้างลำตัวออก มันก็จะบินผงาดขึ้นฟ้าได้เหมือนเครื่องบิน ขณะที่มันพุ่งตัวขึ้นพ้นน้ำแล้ว ก็ยังแพนหางให้แผ่ออก
เพื่อกำกับระดับการบินของมันได้อีกด้วย

Flying fish

From Wikipedia, the free encyclopedia

Flying fish live in all of the oceans, particularly in warm tropical and subtropical waters. Their most striking feature is their pectoral fins, which are unusually large, and enable the fish to hide and escape from predators by leaping out of the water, taking short gliding flights through air just above the water's surface. Their glides are typically around 50 metres (160 ft).

Flying fish taking off
In order to glide upward out of the water, a flying fish moves its tail up to 70 times per second. It then spreads its pectoral fins and tilts them slightly upward to provide lift. At the end of a glide, it folds its pectoral fins to reenter the sea or drops its tail into the water to push against the water to lift itself for another glide, possibly changing direction.The curved profile of the "wing" has an aerodynamic shape that is comparable to that of a bird wing. The fish is able to increase its time in the air by flying straight into or at an angle to the direction of updrafts created by a combination of air and ocean currents.
Genus Exocoetus has one pair of fins and a streamlined body to optimize for speed, while Cypselurus has a flattened body and two pairs of fins which maximizes its time in the air. From 1900 to the 1930s, flying fish were studied as possible models used to develop airplanes.
Exocoetidae feed mainly on plankton. Predators include dolphins, tuna, marlin, birds, squids and porpoises.

Flight measurements

In May 2008, a Japanese television crew (NHK) filmed a flying fish (dubbed "Icarfish") off the coast of Yakushima Island, Japan. The creature spent 45 seconds in flight. The previous record was 42 seconds.
Flying fish can use updrafts at the leading edge of waves to cover distances of at least 400 m (1,300 ft). They can travel at speeds of more than 30 kilometres per hour . Maximum altitude is 6 m (20 ft) above the surface of the sea. Some accounts have them landing on ships' decks.
