Are there really fish that grow in the soil? What kind of fish is rohu and where it grows

There are fish in the world that grow in the soil. This fish is called a lungfish.

As the name suggests, it resembles a human lung. Barramundi live in deserts where water is scarce, and due to the influence of their living environment, they gradually adapt to the natural environment with less and less water resources.

The place where they now live is in the Indian desert. Living in the desert, one can imagine the hardships of this fish's survival. Due to the limited number of precipitation per year, the lungfish are in a state of activity.

There is also only precipitation in a year.

When it is very large, it comes out of the soil to move. When they come out, they will forage and reproduce like other fish. Instead of being dead when they are out of water, they will be very lively after recovery, swimming freely in the water and enjoying the hard-won rain.

When the rain stops and the pool dries up, they choose the land to dig a deep hole. Next, they show off their survival skills. They remove special mucus from the body and harden gradually.

They only expose their mouths to air. The lungfish then reduce the rate of their metabolism and will reach a very low state, at which point they will become like a dead fish. Over time, they will resemble rocks in the shape of fish, just like the surrounding clods of dirt.

Once the lungfish is dormant, it can be under the soil"Sleep"For three or four years.

Barramundi are fish that really live in the land! Unstruck down by the forces of nature, they have evolved abilities that are impossible for fish, and they can survive for up to four years even when they are out of water. Other fish die from lack of water within a few hours of being out of the water.

We have to admire the strong will of the lungfish and the excellent quality of not falling for difficulties.

I saw a video on Weibo before, I don't know if it's in Africa or somewhere, people in that place often go to that kind of dry ground to dig fish at a certain time, and when they dig it out, they are oval, and then they will break the oval thing, and there will be fish in it. And I saw that those fish were very long. Those places are supposed to be poor, the living conditions are not very good, and they are happy to see them dig up the fish.

Then everyone wondered why the fish were in very dry soil, and everyone thought it was impossible at first. Later, someone said that it was because it was the dry season and there was no water, so the fish were dormant in the soil and did not die. When the rain is abundant, they come back to life.

I feel that only this explanation can be justified, anyway, the education I received since I was a child is that fish can't do without water, but we can't say that other people's explanations are wrong, after all, our knowledge is not rich enough to refute others. And I've seen something similar to this one, so I'm more convinced.

When we were in junior high school, our teacher told us one thing, he said that there are fish fry in the soil, and whenever there is water, give enough time to that puddle, and soon fish will grow in the puddle, and no one will throw fry into it. He asked us to remember if it was, and then we found out that it really seemed to be the case, especially the kind of students who lived in the mountains, they said that there was often a pit in the mountain, and if it rained and the water was stored, it would not be long before small fish would come out. The teacher said that the fry are dormant in the soil and will grow into fish as long as there is water.

Fish grow in water, and Thais want to eat fish but dig in the soil? After reading it, I understand.

Rohu is a type of dace that belongs to the genus Cyprinidae of the order Cypriniformes and is a freshwater fish. It is an edible fish that can also be kept in captivity. They have a more heterogeneous diet and can eat small animals and plants in the water.

In addition to rohu, dace also includes rohu, rohu and other species. Compared to other species of dace, they have a wider mouth and are less cold-tolerant. In some parts of our country, it may be inertial to refer to all dace as rohu.

Soil rohu generally refers to dace, which is another name for dace and is one of the common fish in southern China, and belongs to the genus of roce in the family Cypriniformes from the perspective of category. The body of this fish is fusiform, the head is shorter, the mouth is wider, it is curved, it has 4 whiskers, and the surface of the body is covered with a layer of scales. The upper part of their body is blue-gray, and the inside of their abdomen is silvery-white.

The size of this fish is not large, most of them are only about 1 catty. They live in freshwater and are omnivorous fish, and zooplankton and plants in the water become their food. They are also an edible fish that can be bred in captivity.

In addition, although sometimes rohu refers to all species of dace, other times rohu refers only to rohu among dage. In addition to rohu, there are two more common species of dahu, which are rohu and mrigal. There are also subtle differences between rohu and other species of dace.

In appearance, rohu has a wider mouth and a larger curvature. In terms of habits, rohu prefer to live in water with high temperatures, because they are not as hardy as other dace species.

As mentioned above, rohu sometimes refers to all dace, and sometimes refers to a representative species of dace. Whichever it refers to, rohu live in fresh water. Specifically, it is mainly in the south of China, especially in some southernmost provinces, such as Hainan Province and Guangdong Province, that the number of rohu living is relatively large.

Rohu often grow on the bottom of the water, feeding on zooplankton and plants around the sap, so they can often be found in places where life is abundant. In addition, some rohu are raised in captivity and grow in breeding ponds, which are also freshwater.

African barramundi. There is a fish that cannot be said to grow in the soil. It's just that in the dry season, you can use the swim bladder instead of the lungs to breathe.

During dry periods, they burrow into the mud for summer sleep, which can last for months. But there is a time limit. The reason why the lungfish can live outside the water, as its name suggests, can be used"lungs"to breathe.

Because its swim bladder has the function of a lung in terms of physiological structure, it is full of branched vascular networks and spiral valves, and has a short swim bladder to communicate with the esophagus, which can absorb oxygen and excrete carbon dioxide with the swim bladder when there is a lack of oxygen. Interestingly, the barramundi also has a knack for hiding itself deep in the mud during the dry season and building a sturdy one out of the surrounding soil"Small mud caves"A small breathing hole is opened in front of the mouth, and it lies quietly in it for a summer sleep for up to 6 months. When the rainy season comes, it bursts through the hole.

Looks like it.
