Why do flying fish fly?

Question 1: Why do flying fish fly? It's flying fish

Q: Do flying fish have wings?

A: On the sea surface in tropical or temperate regions, you can often see a small flying fish, which people call flying fish. In the coastal areas of China, there are common rays and flying fish. They feed on tiny plankton and come to the eastern part of Hainan Island from the equator in April and May every year to lay eggs, forming a flying fish fishing season. Flying fish's body is streamlined, and there are two developed winged pectoral fins on both sides, which can extend backward to the tail and spread like wings. The caudal fin is divided into two pieces, and the lower piece is longer than the upper piece.

Q: Will flying fish fly because they are happy?

A: The flying fish is dark blue on the back and sides and silver on the abdomen. At present, there are 65 species of flying fish. According to its species, the body length varies from 5 to 46 cm. Flying fish doesn't fly for fun. It only flies out of the water when it is attacked by fierce enemies. The creatures that prey on flying fish in the ocean mainly include sharks, tuna and dolphins.

Q: How do flying fish fly?

A: In order to avoid being hunted, flying fish first speed up their swimming, and their pectoral fins are close to their bodies. When they swim fast enough, they will rush out of the water quickly. Its tail fin hits the water quickly and violently, just like a propeller, giving it the power to take off. At this time, its flying speed can reach 35 miles per hour, about 56 kilometers. Once out of the water, it will spread its pectoral fins and soar beyond the threat of fierce enemies. When the wind direction is right, you can fly two or three hundred meters in the air four or five meters above the water. Sometimes it lands on the deck of passing ships.

Q: Are flying fish the same as birds?

A: Like most fish, it gains strength and speed by swinging its tail fin vigorously. Flying fish can't fly, but gain the ability to stay in the air by gliding. They can swim fast near the surface of the water. If there is danger, their swimming speed can reach 15~20 miles per hour, and then they rush out of the water. Flap the water surface with the tail fin at a speed of nearly 50 times per second, and spread the pectoral fin at the same time, like a bird spreading its wings and flying, more like a rocket launch. Because the air resistance is much smaller than the water resistance, a high gliding speed can be obtained.

Question 2: Why do flying fish fly out of the water? Flying fish fly mainly to avoid predators. Its jumping height is high enough to jump on the deck of a floating ship, and flying fish landing on the board are often found at dawn.

Flying fish is a kind of fish that lives in the upper ocean, and it is the object that all kinds of fierce fish compete for prey. Flying fish don't jump out of the water easily. They only use this skill when they are attacked by the enemy or the ship's engine vibrates. However, this move is not absolutely safe. Sometimes when it flies in the air, it is often caught by seabirds flying in the air, or falls on an island, or hits a reef and dies. Sometimes it will land on the deck of a sailboat and become a delicacy on people's table. This often happens at night, because flying fish have keen eyesight during the day and often fly blindly at night.

Question 3: Why do flying fish fly? Because the front fin of flying fish is very developed, and its tail will generate strong thrust in the water, making it glide hundreds of meters in the air.

Question 4: Why do small flying fish fly? Flying fish has attracted people's interest for many years. With the development of science, high-speed photography reveals the secret of flying fish. Actually, flying fish can't fly Whenever it is ready to leave the water, it must swim at high speed in the water, with its pectoral fins close to its sides and rising smoothly like a submarine. The flying fish beat the water with its tail, and its whole body shot into the air like an arrow that left the string. After jumping out of the water, it spread its long and bright pectoral fins and ventral fins and glided forward quickly. Its "wings" do not flap, but rely on the driving force of its tail to make a short "flight" in the air. Careful observation shows that the second half of the tail fin of flying fish is not only very long, but also very hard. So the caudal fin is the "engine" of its "flight". If the tail fin of flying fish is cut off and put back into the sea, there will be no pectoral muscles as developed as birds, and those broken-tailed flying fish who can't fly by wings can only spend their lives in obscurity in the sea with the regret that they can't fly anymore!

Question 5: Why do flying fish "fly"? Birds fly in the air and fish swim in the water, but some fish can not only swim in the water, but even fly briefly in the air! Flying fish is such a fish.

Question 6: Why do flying fish fly? In the Atlantic Ocean, the Pacific Ocean and the Indian Ocean, when people sail by boat, sometimes they suddenly find a large group of silvery white fish rushing out of the sea. Hundreds of them get together and can fly tens or even hundreds of meters in the air a few meters above the water. This kind of flying fish is flying fish. You must want to know why flying fish fly. It turns out that before flying, there was a strong muscle. Its ventral fin is very long, close to the sides of the body. The lower lobe of caudal fin is longer than the upper lobe. This fin structure enables flying fish to fly. Before taking off, flying fish will swing their pectoral fins and tails violently from side to side to increase their swimming speed to the fastest. Then, with the help of the rising force generated by the pectoral fin and the forward force generated by the caudal fin, you can jump out of the water and take off. When a flying fish suddenly jumps out of the water, its broad pectoral fins spread out on both sides of its body like the wings of a bird, and the buoyancy generated sends it out of the water. Strictly speaking, flying fish can't fly, but can only be regarded as gliding.

Question 7: Can flying fish really fly? Flying fish can fly.

The "flying" of flying fish is actually just a kind of gliding. Scientists used cameras to reveal the secret of flying fish's "flight" and found that flying fish actually took off by stirring the sea water with its "airplane" tail, instead of vibrating its long and wide pectoral fin as people thought in the past. Before flying fish come out of the water, they swim quickly under the water by adjusting the angle. When it approaches the sea surface, it will stick its pectoral fin and abdomen to its sides. At this time, it looks like a submarine. Then, it uses its powerful tail fin to swing violently from side to side, drawing zigzag water marks, generating strong momentum, which makes the fish suddenly breaking the surface like an arrow, and its take-off speed actually exceeds18m/s. After flying out of the water, the flying fish immediately spread their long and wide pectoral fins and glided at a speed of about1.5m/s against the wind blowing from the sea. With the right wind, flying fish can fly 200 ~ 400 meters in the air 4 ~ 5 meters above the water surface, making it the farthest fish in the world. Someone once measured the best flight record of flying fish in the tropical Atlantic Ocean: the flight time is 90 seconds, the flight altitude is10.97m, and the flight distance is1109.5m..

When the flying fish returns to the water, if it needs to take off again, it will beat the waves with its tail before entering the water to increase the gliding power and make it jump out of the water again and continue its short gliding flight. Obviously, flying fish's

In fact, the "wings" did not flap, but made a short "flight" in the air by the driving force of the tail. Someone has done such an experiment, cutting off the tail fin of a flying fish and putting it back into the sea. Because it doesn't have developed chest muscles like birds, it can't flap its wings, and flying fish with broken tail fins can't fly anymore.

Why do flying fish fly?

Marine biologists believe that flying fish fly mostly to escape the chase of large fish such as tuna and swordfish, or because ships are frightened when they approach.

The big family of marine fish is not always calm. Flying fish is a small and medium-sized fish living in the upper ocean, and it is the prey of fierce fish such as sharks, flowers, tuna and swordfish. In the long-term competition for survival, flying fish have formed a very clever skill to avoid the enemy's harm: jumping into the water and flying can temporarily leave the dangerous sea area. Therefore, flying fish will not easily jump out of the water. Only when attacked by the enemy or electrocuted by the ship's engine can this skill be used. But sometimes, flying fish will jump out of the water because of excitement or reproduction, and sometimes flying fish will take off for no reason. Of course, this special "self-defense" method of flying fish is not absolutely reliable. Flying fish flying in the sea, although escaping the attack of the enemy in the sea, often become the "food in the mouth" of seabirds waiting for him on the sea, such as "warship birds".

This is how flying fish jump out of the water for a while and dive into the sea for a while to avoid enemies in the sea or in the air. Flying fish have phototaxis. If a lamp is hung on the deck of a ship at night, flocks of flying fish will come to look for light and fall into a trap and hit the deck.

Question 8: Why can flying fish fly in mid-air? Flying fish can fly on its long and wide pectoral fins. After the pectoral fins of flying fish are spread in the air, they are especially like the wings of birds, which can make the body float in mid-air and not fall off. Of course, it can't flap its wings like a bird and fly up and down freely. It can only glide by the wind. You can glide 100 meters away.

How did the flying fish take off? In the sea, flying fish often meet enemies. It has no sharp teeth and huge thorns, only 10-30 cm long body. It was difficult to deal with the attack of a strong enemy and had to run away. It swims at the fastest speed. Before taking off, it put its pectoral fins close to its sides, its tail swung violently and its direction was upward and forward. When the front of the body comes out of the water, spread the pectoral fins and swing the tail vigorously to jump 7-8 meters out of the water.

Question 9: How do flying fish fly? The flying fish swam quickly and then jumped out of the water to glide.
