Why do jumping fish survive on land? How do they breathe?

The first time I heard about this fish was in "A Bite of China", a father was catching a "jumping fish" for his daughter. This jumping fish is another name for mudskipper, and in some places it is called a mud monkey. It is a fish that spends longer on land than in water, and although it can live on land, mudskippers are essentially fish and do not belong to the amphibians.

Mudskippers are very wild and unlike most fish we know, they like to jump and crawl on land, sometimes even climbing trees. Some friends are very strange, why can they survive on land as fish? In fact, mudskippers need water even on land, and they are afraid of dryness like other fish, and most of the mudskippers we see on land are shallow and still have plenty of water.

You don't see mudskippers jumping and crawling on concrete roads.

Like normal fish, they also have gills, and they need to swim through the gills to extract oxygen in the water, but there is no water on land, so they will store some water in their gill cavities, which is simply understood to be a mouthful of water and go on the road. When their gills are closed, they have a protective film that prevents water loss. When the saliva is almost gone, they will return to their burrows, at which point they can refill the sip of water.

And in order to prevent the eyes from drying out, they also have a water storage bag under their eyes, which will retract the eyes from time to time to moisten the eyeballs. The mudskipper has two small eyes that grow on the top of its head and are close to each other, and it is often seen that the two eyes can move separately, one to observe the surrounding environment and the other to find food or mates.

This mudskipper activity area seems to be very wide, in fact, they are all in their own "doorstep" activities, the slightest danger will quickly jump back into their own hole, even if there are no legs people can come and go freely by the back tail, don't think about mudskippers on land is slow, ordinary people can't catch mudskippers without some skills.

Mudskippers also have a characteristic**Very tender and very thin, especially the tail, which is covered with a lot of capillaries, through ** can directly carry out gas exchange, especially even if mudskippers are active on land, their tails are often soaked in water, which is not only conducive to their breathing but also ensures that the body is moist, not suffocated and dried up.

It is said that mudskippers are very delicious, whether they are braised or stewed, but mudskippers are very similar to a type of goby called "cloud-spotted bare-cheeked goby", and the latter is poisonous and inedible, so you should pay more attention to distinguishing it.

The black hole of literature and science, the **** network invasion and deletion.

A: Jumping fish breathe with gills, it belongs to fish, it is also afraid of dryness, they often put their tails in the water to ensure that the body is moist.

When they are on land, they hold a mouthful of water in their gills, and when the water runs out, they go down into the water again.

Because they came with water, they were just moving in a humid place. After all, it is not an amphibian, and it cannot survive in a particularly dry environment all the time.

Jumping fish are geniuses among fish, they have the habit of foraging off the water, can use their pectoral and caudal fins to crawl and jump on the water, sand and rocks, and their inner gill cavities, ** and tail are respiratory aids.

Because such a fish can keep water in its mouth, as long as there is some water left. Then it can come up and stay for a few minutes, so that it doesn't dry up and dies, and it doesn't affect it.

Because such fish belongs to the kind of amphibian, it can breathe well on land, it breathes through its own mouth, it is very powerful, and it can survive on land for a long time.

Water is essential for human life, and the oceans account for 71% of the world's total area, and these oceans are home to all living things on the planet, including humans. On Earth, there are so many living things that humans are not at the top of the food chain, on the contrary, they are very vulnerable. I believe everyone has seen all kinds of anecdotes, and some people even lost their lives because of a mosquito bite.

Thus, in the entire fabric of nature, man, although a superior species, is not the strongest. There is such a miraculous species on the earth, which can live both in the ocean and on land, and is known as the "black and white" all-you-eat, this species is the mudskipper, also known as the "jumping fish". Friends who are located in Guangdong will be no strangers to jumping fish.

The jumping fish has long been a delicacy on the human table, and it mainly inhabits tidal flats, but it can continue to survive when it is away from the water source.

They love to crawl and jump on the beach or rocks, and they are an amazing fish. However, the jumping fish did not have the ability to bounce all at once, and it took at least 300 million years to do it from the beginning to the realization of the jump. Due to its relatively weak size, the Jumping Fish has too many natural predators in the marine world, and in order to avoid these natural predators, the Jumping Fish begins to flee the ocean.

It's amazing how they can survive on the shore when they come ashore.

In the stereotype, it is difficult for fish to survive once they leave the water source, but the jumping fish does it. The jumping fish retains the distinctive characteristics of a fish, and before coming ashore, it fills its gills with water, and gradually its lungs will change to be able to breathe freely from the air or oxygen.

The jumping fish that came ashore thought that they were "saved", but they did not expect to encounter a more powerful natural enemy, that is, humans. When people found the jumping fish, foodies will never forget it, especially the jumping fish is delicious, known as the "ginseng" in the water, which can play a nourishing role in the human body, so it was sent to the human table and sought after by many people.

Throughout the adventures of the jumping fish, it took 300 million years to go ashore in order to survive, only to encounter humans who almost became extinct.

No, because jumping fish can crawl on land, not all fish live in the water. Jumping fish are amphibians and have strong fins, so they are able to crawl on land.

Yes, jumping fish also need water, they are also generally on concrete roads, and they will store water in their gills, and when the water is consumed, they will return to the water.

Not all fish live in water. Because the jumping fish is covered with a lot of capillaries, the gas exchange can be carried out directly.
