What does a barramundi look like? What kind of fish is the barramundi

Barramundi is one of the few species of fish that can breathe with lungs, this fish can survive in an environment without water, and it is a kind of "living fossil" left over from one of the few preserved ancient races on earth.

Barramundi. Barramundi is a freshwater fish similar to coelacanths, which lives in the equatorial regions of Africa, Australia and South America, and feeds on fish, molluscs, crustaceans, insect larvae, worms, etc. Lungfish have underdeveloped eyesight, but they have a keen sense of smell and at the same time emit a faint electrical current from their bodies to sense surrounding organisms.

The size and color of the barramundi vary greatly, some have markings on the body, some do not, but no two lungfish have the same markings. The markings on the body of the lungfish help them identify themselves.

Lungfish have the physiological characteristics of external gills when they are young, and although they will be retained with growth, they have gradually become smaller and shrunk. The lungfish's fins are able to help them swim freely in the water. These fish are born with a swim bladder with lung function, and when the mud pond and swamp dry up, they can switch to the swim bladder to breathe directly, and can continue to live in an oxygen-deficient environment.

The structure of the lungfish swim bladder is very similar to the lungs, and it can carry out gas exchange and breathe the air on the surface of the water, so some people call the swim bladder of the lungfish "primitive lungs". In fact, lungfish have well-developed lungs, and some species can breathe air and survive even if there is no water.

The "lung" of the lungfish is actually a kind of swim bladder, but its structure is similar to the lungs, which can make the lungfish open its mouth to breathe, but in the face of drought, it is not enough to breathe, the lungfish will dig a hole down, hide in it and seal it with mucus, enter the dormant mode, compress the metabolism, respiration and other life activities to a very low frequency, and stay up until the day when the rain returns.

Lungfish is a kind of freshwater fish similar to coelacanths, the jaw is self-connecting, usually breathes with gills, and can use the swim bladder as a lung to breathe when it dries up, the swim bladder has an opening in the esophagus, called the inner nostrils, dorsal fin, anal fin and caudal fin are healed together, there is no hard bone on the jaw, and there are special tooth plates.

The individual size and color of the lungfish vary significantly, some have markings, some do not, but no two kinds of barramundi have the same markings. Lungfish have the physiological characteristics of outer gills in the juvenile period, and although Hu Kuan will keep the juvenile base as the growth changes, it has gradually become smaller and shrunk, and their growth rate is very fast.

In addition to breathing air directly on the surface of the water, the lungfish also has a very peculiar physiological phenomenon is summer hibernation, the hot summer will dry up the riverbed, so that the lungfish have to burrow into the deep soil, clump the body into a ball, stop feeding and reduce the consumption of various organs of the body to a minimum, into a dormant state. Until the onset of the rainy season, when the riverbed floods again, they will come back to life, break through the soil and go about their normal life.

Hello, it is a pleasure to serve you and give you the following answer: The fish lungs of the flounder are a special lung that allows the flounder to breathe in the water. Its structure is different from that of other fish lungs, and its lung is partially made up of an inflated air sac with a tiny airway that allows oxygen from the water to enter the air sac, allowing the flounder to obtain oxygen.

The methods and practice steps to solve the problem of fish lungs in flounder are as follows:1First of all, it is necessary to make sure that the water number bond type temperature of the flounder is appropriate, too low water temperature will affect the breathing of the flounder, so check the water temperature frequently to ensure that the water temperature is appropriate.

2.Secondly, it is necessary to ensure that the water quality is suitable, as poor water quality will affect the breathing of flounder, so it is necessary to change the water regularly to ensure that the water quality is suitable. 3.

Finally, it is important to ensure that the air quality of the flounder is appropriate, as poor air quality can affect the breathing of the flounder, so change the air regularly to ensure that the air quality is appropriate. Personal tip: Flounder's lungs are a special type of lung that allows flounder to breathe in water, so make sure the water temperature, water quality and air quality are right for flounder's health.

The term lungfish is explained as: a group of bony fish that are closely related to amphibians. The head has an inner nostril that communicates with the mouth.

In a dry environment, the swim bladder can exercise the function of the lungs and breathe air directly. In water, both the swim bladder and the gills work. Lives in fresh water.

There are only a few species in the world, which are produced in Australia, Africa and South America.

Fish do not have lungs. This animal lives in water and generally breathes with gills. Usually water enters through the mouth and then drains out of the gills, where the gill filaments complete the gas exchange.

In addition to respiring with gills, they also have some accessory respiratory organs, such as the African lungfish can breathe with the swim bladder to store oxygen, the loach can breathe with the intestines at the surface of the water, and the mudskipper can breathe with ** and oral mucosa. <

Fish do not have lungs, and this type of animal is characterized by breathing with gills. The fish will keep opening its mouth in the water, the purpose of which is to swallow the water from the air, but the swallowed water does not enter the body, but is discharged from the gills, and the gill filaments on the gills are densely covered with microvessels, and when the water passes, it will complete its volume exchange, so as to obtain oxygen in the water.

1. Fish bladder: In addition to breathing with gills, the African lungfish can also breathe with the swim bladder, because its swim bladder is very similar to the lungs from the structure, so it is called the lungfish. There are many small air chambers of different sizes on the side wall of the ** cavity of the swim bladder, just like the alveoli, and there are small air sacs in the small air chamber, much like the alveoli, through which the fish can store air and breathe.

2. Intestine: Loach is a fish of the loach family, and it is known that it can live in places where there is no water. Usually when the amount of dissolved oxygen in the water is low, it will swim to the surface of the water and usually breathe in the intestines.

And when the pool dries up, he burrows into the mud, and as long as the soil has a small amount of water, it will not die.

3. **: In the northwest of the Pacific Ocean, there is a kind of mudskipper, which is a warm temperate nearshore small fish, which is burrowing and generally inhabits areas such as estuaries. This fish can leave the surface of the water and breathe on land, relying on ** and oral mucosa, so that it can also take in oxygen from the air.

A scattered fish has no lungs, and its main respiratory organ is its gills. But there are exceptions, there is an animal called lungfish in Africa, which can breathe directly in the air with its lungs during the dry dry season.

The lungfish is a freshwater fish similar to the coelacanth. In ancient times, it was bred in large numbers on the earth, and there are still a few preserved remnants of its race, which can be said to be a kind of "living fossil". As its name suggests, barramundi has well-developed lungs, and some species can breathe air and survive even without water.

In the water, fins support the body like feet.

For example, the larramundi has two lungs that meet the glottis and esophagus, the gills and gills are more degenerate, and the heart has two ventricles, one of which receives blood from the lungs, and the arterial cone has valves that separate the blood from the gill from the gill area. Not long ago, some scholars suggested that lungfish are also closest to the extant amphibians in terms of epiglottis cartilage, pituitary structure and hormonal components, lens protein, bile salts, and gill arch muscles.

Fish do not have lungs, and this animal lives in the water and therefore relies on its gills to take in the oxygen in the water. It keeps opening its mouth as it swims through the water, allowing the water to enter through its mouth and then pass through its gills. The gill filaments in the gill cap are densely covered with microvessels, and when they meet the current, they can complete the gas exchange, allowing the fish to obtain oxygen and expel carbon dioxide.

What are the auxiliary respiratory organs of fish:

1. Fish maw: The swim bladder is generally used to regulate the gas, which can make the fish float and sink, but there are also some fish whose swim bladder can play a role in breathing. For example, the African lungfish, their swim bladder structure is special, and the cavity is surrounded by small air chambers, which are divided into a number of small air sacs, which are very similar to the lungs of terrestrial animals, and can store a certain amount of oxygen so that it can breathe.

2. Intestines: Loach is a kind of fish that lives at the bottom of the water, it is generally diurnal and nocturnal, in addition to breathing with its gills, it can also breathe with intestines, so it can also survive in an environment with low dissolved oxygen, and in a place where there is no water, as long as the soil is moist, it will not die.

3. **: In addition to using the swim bladder and intestinal respiration, there are also some fish that can breathe with **, such as mudskipper. This fish generally inhabits the shallow water along the coast, and can come to the shore to hunt at low tide, although it will leave the water, but with the help of ** and the oral mucosa can take in oxygen.

As we all know, there are many types of fish, and some fish are rare. For example, although the legend of the mermaid has been circulating, no one has been able to prove that it really exists. In addition, "The World's Longest-Lived Fish" is a rare fish.

Barramundi is not common, so many people are not familiar with what kind of fish barramundi is, so let's introduce what kind of fish barramundi is.

As for what kind of fish the barramundi is, it is important to know that the barramundi is the "African barramundi". Primarily found in the equatorial regions of Africa, Oceania, and South America, barramundi live in freshwater like most fish. Because of its small distribution, barramundi is particularly valuable.

In addition, the reason why the lungfish is called "lungfish" is that not only can they breathe with their gills, but they can also breathe with their "lungs". During dry periods, barramundi burrow into the mud for summer sleep, which can last for months, but there is a time limit. The swim bladder of the lungfish is well developed, and the anterior part of the entire swim bladder is merged into a single chamber with a short length, and then separates into pairs to reach the posterior end of the body cavity;The side wall of the ** cavity in the swim bladder forms many small air chambers (alveoli) of different sizes, and each small air chamber is divided into many small air sacs (alveoli), and the structure of lungfish is very similar to the lungs of terrestrial animals.

The swim bladder of the lungfish has the function of a lung in terms of physiological structure, which 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.

Another interesting thing about the barramundi is that 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 the barramundi lies quietly in it for the summer to spend up to 6 months of dry season. When the rainy season comes, barramundi burst out of their holes.

The longest-lived fish in the world today is a lungfish purchased by the Shedd Aquarium in Chicago in 1933 and later known as "Old Grandpa", which recently passed away at the age of 90 due to deteriorating health, unlike "The Heaviest Fish in the World". The world's longest-lived fish is due to lack of food and organ failure, and the aquarium where the world's longest-lived fish is located will be euthanized.

In addition, the world's longest-lived fish, "Grandpa", came to the Sheder Aquarium from Australia during the 1933 and 1934 Chicago World's Fairs, and more than 100 million people have seen him in Chicago over the years. [Click to view "The World's Longest-Lived Fish"].
