This fish's flight speed reaches 10 meters per second, capable of flying 400 meters; will it evolve into a bird?
Many fish species live their entire lives in the water.
In our impression, all fish live in aquatic environments, only a few tenacious fish species can temporarily leave the water body.
Fish that stay in the water for a long time have only one ending, that is, death, but there is a kind of fish that not only can leave the water, but also 'fly' to the sky'!
I guess many friends would say, 'fish can 'fly''? That's impossible!
In fact, this kind of fish is not sure whether it can evolve into a bird. But it can 'fly' and its flight speed reaches 10 meters per second, and it can fly as far as 400 meters.
Groups of flying fish taking off
In China's near-sea and South China Sea, there is a fish called 'flying fish'. As the name suggests, it has 'flying' ability.
Flying fish are widely distributed around the world and are a common fish, especially in warm waters, known for their ability to briefly glide.
Friends who often go out to sea know that at dawn, there are often some dead small fish on the deck. These small fish have large fins, and they are flying fish.
The reason they die on the deck is because they failed to take off and fell onto the deck, and after a long time of dehydration, they slowly died.
The graceful figure of flying fish
Flying fish are small individuals, with a maximum of about 50 centimeters, a small fish species, but with a peculiar appearance, with a very developed pectoral fin, like a bird's wing.
The pectoral fin extends to the tail, and the tail is crossed, the long pectoral fin can support their bodies to fly on the water.
Flying fish rely on their streamlined body and pectoral fins to fly at a speed of 10 meters per second on the water surface.
And they can stay in the air for 40 seconds, and the longest distance they can fly is 400 meters, which is admirable. A fish that lives in the water has a yearning for the sky, and it has turned it into reality!
A frontal picture of flying fish
So how do flying fish 'fly'? Scientists used cameras to uncover the 'flying' secret of flying fish. It turns out that flying fish don't 'fly', but they glide!
Flying fish use their crossed tails to vigorously wave the water, thus jumping out of the water, not by the vibration of the fins taking off.
We all know that many fish have the habit of jumping out of the water, such as common ones like crucian carp and carp, often jumping out of the water.
When they jump out of the water, they have an acceleration process underwater, quickly approaching the water surface, and then using the tail to beat the water further to accelerate, jumping out of the water.

Flying fish also use this way to jump out of the water, but their tail fin is more conducive to acceleration, and their swimming speed can reach 18 meters per second, and they can jump out of the water.
After a short glide, they fall back into the water. When flying fish take off again, they need to repeat the above actions. So they don't 'fly', but they glide.
Why do flying fish glide out of the water? Is it just a way of activity or the lifestyle of flying fish?
Flying fish gliding on the water
It's not, the jumping behavior of flying fish is just a way for them to avoid danger. Any fish wants to survive, it will develop in its own advantageous way. Flying fish is just one of them.
Flying fish are attacked by predatory fish such as tuna and barracuda.
In areas with a large gathering of flying fish, there are often many seabirds following and feeding on flying fish. Flying fish also jump out to dodge attacks from seabirds.
In addition, when flying fish are frightened, such as the sound of ships or disturbed by other sounds, they will fly up to avoid danger.
From here it can be seen that the reasons for the gliding of flying fish are many, mainly because of avoiding danger, and its gliding method is one of the ways to avoid danger.
Flying fish also has the ability to 'produce eggs'!, that is, their egg-laying quantity is very large. According to the information, if a small boat encounters a large group of flying fish, the ship may capsize.
Flying fish take off
In the breeding season from April to May, flying fish form large populations and gather together to spawn. The surface of flying fish eggs has filamentous protrusions, which are well suited for adhesion to other objects.
Some places in the ocean have no floating objects and no seaweed, they will spawn eggs or hang on the ship bottom, and the ship cannot bear so many fish eggs, which leads to the ship capsizing.
In fact, the gliding method of flying fish is just one of the ways they face danger. Any fish wants to survive, it will develop in its own advantageous way. Flying fish is just one of them.
The wonderful nature is full of surprises, many organisms have their own growth and survival ways, there are still countless biological species on Earth, which is still a mysterious existence.
We need to explore, discover, and the more we understand nature, the more we admire nature. Only with a curious heart, we can 'walk ten thousand miles, read ten thousand books'
And the way of survival of flying fish is also worth learning. It's not just learning how they escape, but learning how they solve problems, learning their adaptability and way of avoiding danger, which is a very good method.
This is the understanding of flying fish's ability to fly, if there are any mistakes, please point out, I will correct it, I hope it can inspire you, if you find it useful, you can collect it, like it, share it to learn more, follow the headline number 'Flying Fish Commander', thank you all.
