The second distinctive feature of the sturgeon is its cone-shaped head. The jaw of this fish can be easily pushed forward. By the way, there are absolutely no teeth on it. The lips of this fish are dense and fleshy. Sturgeon structure. invertebrate.

The sturgeon is famous for its excellent fertility. By the way, for spawning, he goes into fresh waters. He prefers to spend the winter in them. The sturgeon’s diet includes shallow inhabitants of the deep sea, such as:

Sturgeon

This fish is one of the most popular in the marine industry. Scientists identify more than 10 species of sturgeon. Each of them is united by a 5-row structure of special scutes of the beetles (rhomboid bone scales).

Loach habitat and abundance

These fish adhere to deeper areas of water bodies, and accumulate in them in large numbers. Loaches lead a gregarious lifestyle. But on shallows with a fast current, they prefer to stay alone, hiding between stones.

The abundance of char, like many fish, is considered dynamic. They can be numerous in certain places, and then disappear completely, and recover again after a while. In the 80s, these fish practically disappeared from a huge number of biotopes, due to their poor ecological situation. But in the 90s, the species recovered and became numerous.

Char. a fish with a spotted color.

At the same time, the distribution of char is uneven. Presumably, this species is more numerous in the east, and in the west there are fewer of these fish. In certain ponds for complex purposes, char is found in large quantities.

Shark

The number of fish that do not have solid plates on the body, the shark is classified conventionally. She has them, but their size and shape are non-standard. In structure, shark scales resemble teeth. Their shape is rhombic. Such small “teeth” fit very tightly to each other. Some sharks have spines all over their bodies.

Why is this predator classified as a fish without scales? Everything is very simple. The hard, jagged plates covering her body are very smooth. If you look exclusively at the shark’s skin, you might think that it belongs to an elephant.

This predatory aquatic creature is famous for its razor-sharp teeth. They are cone-shaped. A feature of the shark is the absence of a swim bladder. But this does not prevent it from being a full-fledged fish, since maneuvers are performed due to the presence of fins. This aquatic predator is classified as a cold-blooded animal.

Sturgeon

The fish is considered noble and delicious. However, eel and shark meat is also used in the best restaurants. With this in mind, scholars of Judaism offer another explanation for being included in the list of non-kasher fish without scales.

There is a connection with gluttony. Eating too much food for pleasure, not satiety, is a sin. Salmon and similar “naked” fish dishes are so tasty that it is difficult to stop. The Jews Save Themselves From Temptation.

Sturgeons are gigantic. In 1909, an individual weighing more than 300 kilograms was caught in the North Sea. The length of the fish was approaching 3.5 meters. There was no caviar in the trophy. Meanwhile, from the 200-kilogram sturgeon caught in the Neva in the 19th century, 80 kilograms of the delicacy were extracted. Caviar was sent to the royal table.

Due to its prevalence in the waters of the Russian Federation, sturgeon is often called Russian. There are especially many fish in the Black, Azov and Caspian Seas. Sturgeons also live in rivers. In addition to the Neva, scaleless fish are found in the Dnieper, Samur, Dniester, Don.

What char eats

These fish feed on molluscs, chironomids, oligochaetes and other zoobenthophages. In addition, their diet consists of caviar from other fish. Loaches are on the same food stage with minnows. And since these two species live together, they compete with each other.

Burbot

This is the only representative of cod in fresh waters. Why fish without scales, scientists argue. The main reason is the habitat of burbot. It stays closer to the muddy bottom. It’s dark there. The scales of most fish are designed to reflect light. So animals are less visible to enemies.

The plates also prevent the formation of folds on the skin during fast movement. Bottom fish, including burbot, are unhurried. The protective function of the scales remains. Burbot “sacrifice” it for the convenience of movement in slimy silt.

Burbots are found in rivers and lakes of all continents. Preference is given to clean and cool rivers, lakes, ponds and reservoirs. Burbot does not tolerate high temperatures. In the summer it seems that the fish is extinct. In search of coolness, a representative of the cod family goes to the depths.

In front, the body of the burbot is cylindrical, and towards the tail it tapers, becoming like an eel. The skin can be removed like a bag. In the old days, the material was dressed like animal skins and went to tailoring boots. Burbot leather products are also made by some modern designers.

Fish without scales, their features, types and names

In the world of the deep sea, there are many amazing living organisms, one of which is fish without scales. In Judaism, they are equated with unclean reptiles, so the Jews do not eat them.

Scales perform a number of important functions, including:

  • Disguise;
  • Protection against parasites;
  • Improved streamlining;
  • Increase in speed, etc.

A fish without scales is forced to adapt to life in water spaces differently. For example, if a predatory fauna is nearby, it, trying to disguise itself, will bury itself in the silt. But this is not the only reason for the neglect of the Jews. People professing Judaism believe that the Creator could not create such representatives of the animal world in his own image, because their appearance is repulsive. And there really is a rationale behind it.

A snake-like fish with a slippery body can easily escape even from a large and fast predator. In addition, its mucus can be toxic, that is, dangerous to other aquatic life. Let’s talk about some of these types.

Common fish without scales

Among the wide variety of the fish world, the division into aquatic inhabitants covered with scales and some species without it is widespread. Widespread religions (Judaism, Islam) prohibit the consumption of fish without scales. This is because many of the scaleless aquatic creatures are scavengers, and some are poisonous. In this article, we will consider which fish does not have scales.

Moray

These are also snake-like fish. Moray eels grow up to 3 meters in length. The weight with this size is approximately 50 kilograms. However, it is difficult to spot moray eels. Most species have camouflage coloration and reliable cover. Waiting for the prey floating by, moray eels are hammered into bottom caves, cracks between stones, depressions in the sand.

Facts of moray eels attacks on divers have been recorded. Most of the precedents have occurred during night diving. During the day, moray eels are inactive. If it is not a fish that catches a person, but a person who catches a fish, the scaly creature goes to the table.

Moray eels are considered a delicacy. The title was deserved in ancient times. Moray eels were especially appreciated in the Roman Empire. Modern restaurants also delight with a variety of fish menus.

Pearl fish

This fish rarely catches your eye, as it settles inside shellfish, starfish and cucumbers. Pearl mussel prefers the waters of the Atlantic Ocean. Modest sizes help fish to crawl into houses of invertebrates. Also, the animal has a thin, plastic, nimble body. It is translucent, like a golomyanka

Living in oysters, scaleless pearl fish absorb their mother-of-pearl. Hence the name of the species. It was discovered after finding one of the fish in a caught oyster.

Mackerel

This is a sea fish without scales. The entire spindle-shaped body of the animal is devoid of plates. Mackerel also has no swim bladder. At the same time, schools of fish are kept in the upper layers of water.

Mackerel is a commercial fish with fatty, nutritious meat. The Jews avoid him for religious reasons. Adherents of other faiths offer hundreds of recipes with mackerel meat. These are salads, soups, and first courses.

Golomyanka

This fish is endemic, found only in one body of water on the planet. It’s about Lake Baikal. In its waters the golomyanka looks like a fluttering bloodworm. The fish is white without scales and with large pectoral fins spreading out to the sides like the wings of a butterfly. The size of the endemic is comparable to the insect. The standard length of the fish is 15 centimeters. Males of some species reach 25.

Golomyanka is not only naked, but also transparent. The skeleton and blood vessels are visible through the skin of the fish. Sometimes fry are visible. In fresh and cold waters, the golomyanka is the only viviparous fish. The offspring cost mothers their lives. Having given birth to about 1000 fry, the golomyanka dies.

Shark

In fish without scales it is included only conditionally. There are plates on the body, but placoid. These have thorns. They are directed in the direction of movement of the fish. In stingrays, for example, the same scales have transformed into tail spines.

Most fish have cycloidal scales, that is, smooth. Due to the placoid plates, the shark’s body looks rough, like that of elephants or hippos. The inhabitants perceive this as the absence of scales, rather than as its special type.

The shark has scales, but it does not look like we are used to

Acne

Refers more to catfish than snake fish. Most of them are without scales. In the photo, the fish looks like a large leech. The eel has a similar oral apparatus, however, the fish hunts using an electrical impulse.

Outwardly strange, living near the bottom, eels confused the ancients. Aristotle, for example, believed that serpentine fish arise spontaneously from algae. The exact nature of the origin of eels was determined only in the 1920s.

Eel is both a river fish without scales and sea fish. Serpentine creatures are born in the Sargasso Sea in the Bermuda Triangle. The young growth, caught by the current, rushes to the shores of Europe, entering the mouths of rivers and climbing along them. Eels grow up in fresh water.

Fish without scales. Description names and types of fish without scales

Fish without scales are forbidden by the Jews. In the holy scripture “Torah” it is indicated that only species with fins and lamellar coverings can be eaten. Fish without scales have been compared to filthy reptiles like snakes, shellfish.

There are several explanations for this. The first has to do with the impure nature of the species. Fish without scales, as a rule, bury themselves in silt and feed on carrion. The second explanation is the toxicity of many “naked” inhabitants of reservoirs. There is also an ethical interpretation.

Fish without scales are repulsive in appearance. Those who serve the Creator should not eat such things. The combination of these factors led to the “recording” of naked fish in non-kasher products along with pork, shrimp, and blood sausage. So, a complete list of fish without scales:

From the point of view of science, it is mistakenly included in non-kasher fish. The animal has scales, but small, sparse, thin and tightly pressed to the body. Such is imperceptible at first glance. But it’s hard to miss the fish itself.

In length, catfish reach 5 meters, and weight gain 300-450 kilograms. An animal of this size goes to a depth where it can freely hunt.

Being predators, catfish draw in themselves by passing prey, sharply opening a large mouth. Also, giants of freshwater reservoirs love to feast on carrion.

Catfish often feed on carrion
