The man accidentally found an oversized river mussel by the lake! How peculiar is the appearance of

Speaking of river mussels. I believe that friends should be familiar with it, river mussels are a common aquatic creature in daily life, and often appear in various lakes or rivers. Generally speaking, mussels should all look similar, like oversized shells.

However, when a man in Jiangxi was playing by the lake, he accidentally found an oversized river mussel.

In terms of appearance, the man found that the mussel was very large, and the appearance was also very peculiar, not like the common ordinary river mussel in life with an oval body, but showed a long strip-like body, which looked particularly weird. What's more, this peculiar river mussel also likes to live in the cracks of the stones, which is really incredible, I don't know what kind of creature it is. The man may also be very curious, so he posted the ** of this super-large river mussel on social platforms, hoping that some netizens can tell him what kind of creature it is.

Unexpectedly, some netizens said that this creature is not an ordinary river mussel, but a keel clam called a dragon bone clam and is a second-class protected animal in my country. This time, the man found that its location was Poyang Lake.

side, and the keel clam happens to live in Poyang Lake, so it is obvious that the super-large river mussel that this man found this time should be the keel clam undoubtedly. National second-class protected animals.

Of course, you can't catch it at will, so the man listened to the opinions of netizens and released the oversized river mussel.

The number of keel clams is still relatively small at present, otherwise it would not be listed as a second-class protected animal in China. However, as the ecological environment has become better and better in recent years, these rare wild animals.

The number also increased, which is why this man was found by the river this time. This also means that the local ecological environment is relatively good, which is why this rare wild animal will appear. In general, when you find all kinds of unknown creatures in the wild, try not to catch them at will, maybe these strange creatures are protected animals.

I myself once touched a 9-pound one, 38 centimeters long, bigger than a basin. It has been reported on the news that more than 20 catties of river mussels and sea mussels can weigh up to about 200 kilograms, and their lifespan can reach 80-100 years, or even more than 100 years.

Not only slender and living in the hole, but in fact, this is another species of river mussel, after inquiry, it is suspected to be the national second-class protected animal keel clam clam, and it is also the only burrowing mussel species.

The mussel is oval and oval in shape. Chitinous is thin and brittle. The two shells are inflated, and the back sometimes has rear wings.

螠蛏 [yì chēng], commonly known as "razor clams", is a bivalve clam shellfish that lives in the ocean and is a common seafood ingredient. The shell is brittle and thin, oblong and flattened, from the top of the shell to the ventral margin, there is an oblique groove, so it is called a clam. It prefers to live near estuaries with fresh water inflow, and is a common mollusk along the coast of our country.

Clams belong to the phylum molluscs, petal gills, heterodonts, curtain clams, and razoraceae shellfish, and are one of the four major cultured shellfish in China. It is widely distributed in the coastal areas of China and Japan, and is mainly distributed in the north and south along the beach flats in China, and its output is quite abundant. Ningbo coastal area has many tidal flats, has a unique advantage in breeding razor clams, is Ningbo public sea products, Ninghai long street area, facing Sanmen Bay, perennial a large amount of fresh water injection, seawater salty and suitable, rich bait, coating quality to sediment-based, so razor clams grow fast, the individual is large, the meat is tender and fat, the color is white and fresh, so it is named Changjie razor clams, according to the Qing "Ninghai County Chronicles" record:

Clams, mussels, to the seed of the field is called the razor field, narrow and long like the middle finger, a Shih Tzu tongue, the beauty of the words.

The ** you sent should be razor clams. Razor clam is a seafood shellfish. Mollusca.

The shell has two fans, the shape is narrow and long, the outside is egg yolk, the inside is white, it lives in the seawater near the shore, and it can also be artificially cultivated, and the meat is delicious. There are types such as razor clams and razor clams.

One day, my grandmother and I went to the mud to catch a river mussel, and I touched a big river mussel in the mud. Its fan-shaped, tightly closed hard shell had a circle of patterns growing around it, in the sun'Under the light, shimmering with a dark green luster, my grandmother, Sizhou Bi, told me that the colorful and expensive pearls were produced in the body of the mussel.

I speculated that the square mouth was the mouth of the mussel, and the white flesh was its tail, and suddenly, a miracle happened, its tail grew longer and longer, and slowly bent again. Then, with a flick, a filamentous mass erupted from the tail. The mass slowly spread, and gradually sank to the bottom.

After about two minutes, I noticed that there were a lot of pin-like fish moving around in the mass. Slowly, these little fish moved more and more happily, and finally rushed out of the filament, shuttling around in the water, I wondered, how could the mussels spew out small fish? I checked the books, and it turned out that these were the young of the mussels, not the small fish.

There are many mysteries of nature, and only those who are not afraid of difficulties and are willing to study can uncover those mysteries.

The large river mussel (scientific name: potamilus capax), also known as the fat pocket pearl mussel, is a freshwater mussel endemic to the United States. They are listed as critically endangered by the International Union for Conservation of Nature (IUCN) and are being protected by Appendix I of the International Convention on Endangered Species of Wild Fauna and Flora.

River mussels are widely distributed in water bodies such as rivers, lakes, reservoirs, ponds and rice paddies, and usually live in sediment at the bottom of the water. In its natural state, only the back end of the mussel's body is exposed from the sediment, and the inlet and outlet pipes are often opened to maintain the continuous flow of water in the body and maintain the normal progress of life activities. River mussels usually live in patches or bands in shallow waters, and prefer flowing, clean, fertile water.

It is less abundant in large rivers and is only distributed in shallow water areas of river bays. There are not many species of river mussels in ponds, but they are more abundant, and less in rice fields.

River mussels are generally suitable for living in neutral or weakly acidic and weakly alkaline water, but the requirements for different species are also different. Both the dorsal horn toothless mussel and the crested crested mussel can live between pH 5 and 9. Spinnaker mussels, on the other hand, often need to be stable in water with pH 7 8. Mussels do not require much dissolved oxygen, with a low limit of about 3 milligrams of liters, but if they fall below this limit for a long time, they will die in large numbers.

The mussel has a strong drought resistance, and the mussel buried in the soil will not die after about half a month of drought, but it will die in a few hours when exposed to the air, especially in the summer sun.

The mussel has a very weak locomotion ability and mainly relies on its axe feet to plow slowly through the sediment at the bottom of the water. During exercise, the mussel body is shallow buried in the sediment, stretches out the axe foot and inserts it into the sediment forward, a large amount of congestion makes the axe foot swell and adheres to the mud and sand, and then the muscle contraction pulls the mussel body to slide forward for several centimeters. River mussels are mostly active at night and rarely during the day, but they are also common on cloudy days.

1. Some species have disappeared from their heads (mussels, oysters).

2. There are foot degeneration (scallops) and sedentary species without feet (oysters).

3. There are water inlet holes and water outlet holes.

4. There are shells in vitro.

5. The secondary body cavity is degenerated, leaving only the internal organs of the pericardiac cavity, gonads and excretory organs, while the primary body cavity exists in the space of various tissues, and there is blood flow in it, forming blood sinuses and open tube circulation.

River mussels are omnivorous. Some plankton, such as rotifers, flagellates, green algae, diatoms, and fragments of plant leaves, are its food. River mussels cannot actively chase food, and can only rely on the gilia on the gills and lip flaps to swing, so that the food in the water enters the body with the water flow from the water inlet hole, so the food types of mussels vary greatly with different regions and Ji Ye.

The food that enters the body is filtered by the gills, moves ventrally, enters the food groove, and then advances forward to between the left and right pairs of lip flaps, and enters the mouth. [2]

River mussel is a more common animal we are more common, it is a kind of animal that belongs to the soft body, growing in the river, when we were children, we often catch river mussels from the river, although many people have seen river mussels, but the specific may not be very well understood, the following article will make a specific introduction.
