If within the first two hours the victim is not provided with medical care, then he will die.
3.
Opens the top three most dangerous fish in the world. It is a relative of the catfish. Its danger to humans and any other living creature is that the body of an eel has a discharge of 550 volts, which is fatal. Death from contact with the body of the fish occurs instantly. An electric shock can stun even an adult horse. You can’t take such fish with your bare hands. These predators do not have to use their jaws to catch prey. It is enough to strike the body to the victim died. In length, electric eels can reach 3 meters, and weigh up to 40 kilograms. A dangerous creature lives in the Amazon and South America.

The shark reaches gigantic growth: the body length ranges from 2-4 meters, and the weight is up to 250 kg. She can live both in fresh and salt waters. Therefore, these fish often penetrate into rivers and reach lakes. Cases of detection of a bull shark in the rivers of Missouri, Kentucky and Illionis have been recorded.
The most dangerous fish that pose a threat to humans are not found very often in nature, but they are there, and the enemy must be known in person. Fish are considered one of the most beautiful creations of nature, especially if we think about colorful tropical fish that delight the eye of the beholder. Even men often call affectionately their lovers "my fish." But we must not forget that there are some species that pose a mortal danger to all living things on earth. Compared to these dangerous fish species, the shark seems like a "little kid."
What are the terrible aquatic inhabitants, and what is the threat posed by them?
The most dangerous fish for humans review
Electric eel
This creature can actively defend itself if it was attacked, or if it seemed to him that it was attacked. Such a situation may result in electric shock with a voltage of 600 volts, which will be enough to kill a person or any other creature. It is found in South America and the Amazon.
Tiger fish
Tiger fish, or goliath fish, is a ferocious predator. Razor-sharp teeth help her hunt. The weight of a monster can reach fifty kilograms. This is one of the most bloodthirsty and dangerous freshwater fish. Can eat animals accidentally caught in the water, and even attack a person. It is mainly distributed in Africa, especially in Lake Tanganyika and the Congo River.
Dangerous Gunch Fish
Goonch Fish or Som Bagari is found in the Kali River (also known as Gandak), flowing between Nepal and India. What makes this type of catfish especially dangerous is that it loves the taste of human flesh. This fish is the main culprit in the disappearance of people in the Kali River region. Individual individuals can weigh up to 140 kilograms. It can attack a person even with a crowd. It is believed that fish began to nourish the cannibalistic craving for human meat because of human customs. The Kali River has long been used by the local population to get rid of the bodies of the deceased. The partially burned corpses of the dead, after the Hindu funeral rites, are dumped into the river.
The most dangerous fish stone
Stone fish, or wart, is one of the most dangerous and strange species of fish. This fish is considered the most poisonous in the world. As a rule, the wart lives among coral reefs, imitating a stone. The similarity to the stone allows her to remain invisible until you step on it, but this step can be fatal. Stone fish is known for its very potent venom, and its bite can be fatal. The effect of the defeat lasts for long hours, a person dies in terrible agony, and there is no antidote from the poison of stone fish. There is a dangerous werewolf in the shallow waters of the Pacific and Indian Oceans, as well as in the waters of the Red Sea, off the coast of Australia, Indonesia, the Philippines, the Marshall Islands, Fiji and Samoa. The Russians have a real chance of encountering dangerous fish on the beaches of Sharm El Sheikh, Hurghada or Dahab.
Snakehead
Snakehead fish, or snakeheads, were first discovered in Russia, China and Korea. This predator is found in the rivers of the Far East, including in the Primorsky Territory. But today, this fish can be found in ecosystems and other countries. Usually snakeheads live in small, overgrown with vegetation, well-heated reservoirs.
The snakehead eats all living things in the water. It reaches one meter in length, weighs up to ten kilograms, but the largest of the fish caught weighed thirty kg.
Snakehead is interesting in that up to five days can do without water. In dry ponds, he digs deep into the silt and expects the next rainy season there. It can crawl a considerable distance on land to a nearby body of water. It feeds not only on fish, but also amphibians.
Vandellia
Vandellia (Vandellia cirrhosa) or Kandirý. Candiru is a freshwater fish that lives in the waters of the Amazon. This fish is one of the worst monsters on the planet, despite its small size. The dimensions of her body are only 2.5 cm in length and 3.5 mm in thickness. The trouble for humans is that this fish, like a magnet, is attracted to itself by blood and urine. For her, these are power sources.
Vandellia easily penetrates the anus, vagina or penis of a person and begins to feed from the inside with human organs, causing excruciating pain to the victim. What is really scary is that, in most cases, amputation is the only way to get rid of this predator.
However, it should be noted that human cases are extremely rare. Usually catfish vandallia swims in the gills of another freshwater fish and feeds on the blood of the blood vessels of fish gills. Because of its bloodthirstiness, the small freshwater catfish was called the “Brazilian vampire”.
Piranha
Piranhas - small fish in South America and Brazil, are extremely dangerous because of their gluttony. South American Indians call this fish, which reaches only 30 cm in length, "toothy devil." Sharp triangular piranha teeth pose a danger to any living creature caught in the water. They attack prey in large flocks, leaving in a short time only bones from their prey.
Hedgehog fish
Hedgehog fish is known for its deadly poison. The liver, ovaries, intestines, and skin of this fish are containers for storing tetrodotoxin, a substance that affects the brain, causing paralysis or death. Therefore, eating this fish is highly undesirable.
Hedgehog fish is one of the most common inhabitants of the oceans and tropical seas. In case of danger, the hedgehog takes the form of a ball, absorbing water and increasing in size.
Jellyfish box
Jellyfish-box or sea wasp (scientific name - Chironex fleckeri) is considered one of the most dangerous creatures in the world. This poisonous inhabitant of the seas can kill an adult in three minutes. And to be more precise, the poison of one jellyfish is enough to kill 60 people.
It cannot be said that many people died from the poison of this dangerous inhabitant of the deep sea. According to reports, over the past hundred years, the jellyfish wasp has caused the death of one hundred people.
Since the jellyfish has a pale blue transparent color, it poses a real danger to swimmers, because it is difficult to notice against the background of sea water.
It is found in tropical areas of the Pacific Ocean, in the coastal waters of Australia. It is worth clarifying that for humans, they usually live in warm tropical waters, although there are exceptions. There is an effective antidote from the poison of deadly jellyfish, stung swimmers do not have time to get help, because the heart stops after three to four minutes, and the person does not even have time to get to the boat, and even more so, to the shore.
Payara
Payara, or a mackerel-shaped hydrolytic, is known as a vampire fish. It is also called a dog fish. This fish is so bloodthirsty predator that it is considered more dangerous than piranha. The body of this terrible fish can reach a little more than a meter in length. Payara lives in the fresh water of the rivers of South America, especially a lot of it in the rivers of Venezuela.
Devours everything. Interestingly, they pose a real threat not only to humans. For example, a vampire fish is the only fish that can handle, that is, eat, dangerous piranha.
This little fish managed to grow several myths. It feeds on blood from the gills of larger fish. To do this, Candira penetrates inside, holding in place with the help of spikes and damages blood vessels. Some sources claim that fish finds prey by the smell of ammonia. Others are convinced that Candiru seeks victims through sight. Saying that this fish can jump out of the water and enter the human genitals is a myth.
It is also controversial that fish can enter a person when he is in the water. This is stated by the scientist Stephen Spot in the book "Candira: about life and legends about blood-sucking catfish." But this does not mean that in the waters of the Amazon you can relax and visit the river without underwear and safety measures. There are many other animals that can cause a lot of trouble, and one of them is presented further. Be that as it may, Vandellia is included in the rating - top 10 most dangerous fish in the world.

Despite their small size and kinship with carps, piranhas keep almost all the inhabitants of the Amazon at bay. They can even eat a crocodile, the most experienced of which depart from this fish, turning over and substituting the most protected part. They choose reservoirs with a rich living creature, because they are very voracious. A drop of blood in the water attracts their attention for several kilometers. Officially, not many deaths from piranha teeth were recorded, but the number of people they turned into disabled people is very large. But piranha also has its own predator. Locals catch them with fishing rods, in the river caimans hunt for them. Yes, and get on a tooth to their fellow tribesmen for them is easy.

This fish does not specifically hunt humans. She misses the other inhabitants of the sea. Her saw serves as a kind of locator, is used to loosen the soil and shows itself well in defense and attack. Yes, and these fish are mainly nocturnal. But if the fish-saw seems that a person is trying to attack her or she mixes it with an animal, he will not be greeted. Rostrum is covered with modified scales, due to which it causes terrifying lacerations. Fish is on the red list of endangered species and trade is prohibited.

These fish can harm a person only if he himself forces them. This usually happens if they are stepped on by negligence. They lead a bottom lifestyle and are well camouflaged. If their sting hurts a leg or arm, then you can get off relatively easily. But if you get into the body or head, the risk of death increases significantly. That is how the famous host Steve Irwin died, who the pintail hit in the chest.
6. Brown puffer or puffer fish
A person consciously runs the risk of death in the case of this fish. It is a signature dish in many Japanese restaurants. Its use causes mild euphoria in people. Moreover, almost all parts of the fish are poisonous. Some of them are thrown away, others require special treatment. A person must not only undergo training and have the appropriate license, but also be able to provide first aid in order to prepare a puffer in a restaurant.
Previously, there was a custom according to which the cook had to eat it or make hara-kiri in case of poisoning the visitor. An antidote to the toxins of this fish does not exist, help will be to maintain cardiac and respiratory activity. Since fish receives poison along with food, they have recently learned to grow absolutely harmless puffer. But it is not widespread. Food lovers want to tickle their nerves, and restaurants sell dangerous food at a higher price. Because of its poison, brown puffer deservedly takes place among the 10 most dangerous fish in the world.

She attacks any creature that is smaller than her size. Given that its length reaches 2 meters and its weight is 50 kg, the diet of barracuda is diverse. A person can become a target for an attack, although this happens quite rarely. But precisely for this reason, barracuda is on the list of the most dangerous fish on the planet. Even smaller relatives can be in her diet. The fish leads a solitary lifestyle, only young animals are lost in schools. It lives only in areas with clean water, as it relies heavily on vision during hunting. In rare cases, large barracudas can hunt flocks of fish together. They do not specifically attack people, in most cases, divers themselves provoke them.

The warty leads a sedentary lifestyle and is very well masked. You can step on it and on land, where it gets during the tides. The spikes that she lifts in any danger easily pierce a person’s shoes. She has been awarded the title, and the pain in contact with her is such that some people want to cut off a stung limb. Pain shock can cause a person to simply choke under water. If he gets to land, he will be a little helped by applying a tourniquet and heating the bite, as this destroys the poison. But this can only alleviate the situation a little, without timely medical assistance, a person will die, and recovery can take months.

These fish are practically not afraid of other predators. Only young caimans sometimes inexperienced attack them with dire consequences for themselves. The bodies that generate electricity occupy 4/5 of the body length and allow them to beat at the right time with a discharge of 300 to 1300 Volts with a current of 1 Ampere. The electric shock of an adult electric eel can stun a horse. Such a blow to a person can be fatal. Therefore, electric eel is on the third line in the ranking of the most dangerous fish in the world. They also use their electric organs as a locator. Electric acne can reach a length of up to 3 meters and a weight of up to 40 kg. The Indians got the hang of catching them, first launching a herd of cattle in their habitat. This fish is extremely unpretentious and survives in swamps with stagnant water, constantly swallowing air from the surface. They are often bred in large aquariums.
2.
The most famous and largest participant in the list. The size of an adult shark ranges from 4 to 5 meters. The largest, of reliably measured individuals, had a length of 6.1 meters. The force of the bite of this fish loses to the crocodile, but the structure of the jaw and the sharpness of the teeth allow the white shark to literally tear off pieces even from larger animals. A common tactic when hunting a large animal is an unexpected attack and bite, after which the shark expects the prey to weaken. They attack people. There is a theory that they do not do this on purpose, since they have a habit of biting everything incomprehensible. In addition, a shark can confuse a person in fins with habitual prey. Cases were recorded when these fish attacked small vessels. But the man more than repaid them for 139 attacks recorded in 21 years. Today, the number of sharks has decreased significantly, in some countries they are protected by law.
1. Bull Shark or Gray Bull Shark
The most dangerous fish in the world - bull shark, also known as a blunt shark. Official statistics are not able to reflect the real number of attacks by predators on people. This is especially true for bull sharks. The halo of its habitat includes third world countries where accounting is poorly set. Plus it is often confused with other species of sharks. The combination of a number of factors makes it very dangerous for humans. Firstly, the body length reaches 4 meters and weight up to 400 kg. Secondly, she lives quietly in fresh water and often lives in ponds near densely populated areas. A person can be deceived by her slowness and even some clumsiness, but if necessary, she develops a great speed. She has the largest bite force among sharks and reaches 6,000 Newton, and before she can use her jaw, she can stun the prey with a blow to the head. Added to this is completely unpredictable behavior and increased aggressiveness. Unlike other sharks, which can retreat after receiving a strong blow or rebuff, the active resistance of the victim can further anger the bull shark. There have been cases when the gutted bull shark began to eat its own insides.

Predatory fisheat not only plant but also animal food. In other words, we are talking about omnivorous species. Some of them prey not only on underwater inhabitants.
Trivalli, otherwise called karangs, for example, jumps out of the sea, capturing birds flying over the surface. Sharks and catfish are known for attacks on humans.
Freshwater Fish of Prey
Catfish
These carnivorous fish pondsrepresented by more than 10 species. Most of them are aquarium. They are small. But ordinary catfish is the largest predatory river fish. In the last century, 5-meter individuals weighing about 400 kilograms were caught. In the 21st century, the maximum weight of the catfish caught was 180 kilos.
Small predatory fishamong catfish - a glassy look. In the natural environment, its representatives are found in India. The glass catfish is transparent, only the head does not shine through.
Zander
There are 5 types of them. All have an elongated body with large scales. She covers all the fish. She has an elongated, pointed head. It is slightly flattened on top. Sharp and high fin sticks out on all backs of pike perches. He, like the entire top of the fish, is gray-green. The abdomen of the animal is gray-white.
Zander - large predators, may exceed a meter in length. The weight of the fish is approximately 20 kilograms.
Piranhas
Piranha 50 species. All predatory, live in fresh waters of the southern tropics. The length of the piranha does not exceed 50 centimeters. Externally, the fish are distinguished by a flattened body from the sides, silver, gray or black color of the scales. On a dark background, yellow, scarlet or orange marks may be present.
All piranhas have their lower jaw extended forward. Triangular teeth are visible. They are sharp and close to the top. This adds destructive power to a fish bite. Adult piranha easily crushes a stick with a diameter of about 2 centimeters.
Pike
There are about 10 species of them in fresh water bodies. Aquitaine pike, living in the waters of France, was discovered only in 2014. The Italian look is isolated from others in 2011. The Amur pike differs from the usual fine silver scales and is smaller.
There are still fish with black stripes above the eyes. These live in America and do not gain more than 4 pounds.
The largest in the family is maskinong. The sides of this pike are covered with vertical stripes. Maskinong extends up to 2 meters, while weighing almost 40 pounds.
Pike - predatory fishplaying the role of a water orderly. The first to fall into the mouth of a predator are weakened fish, amphibians. The family has developed cannibalism. Large pikes eagerly devour smaller ones.
Perch
There are more than 100 species in the family. About 40% of them are marine or semi-aisle. Among freshwater perches, the most common riverine perch. With others, it is combined with greenish transverse lines on the sides.
The pattern is poorly expressed if the bottom in the pond is bright. If the bottom is dark, for example, silty, stripes on the sides of saturated color perches.
Perch - freshwater predatory fisheating its own fry. This is true in reservoirs where perch prevails among other species. In addition to juveniles, adult animals eat other small fish.
Arapayma
This is a tropical predator that lives in the tributaries of the Amazon. There is a bone plate on the elongated and flattened head of the fish. At the same level with her is a wide mouth of arapaima. Her body is thick, but flattened from the sides, tapering to the tail.
The fins, like eels, have grown together. However, the body of the fish itself is not so long. Arapaima looks like chopped, shortened and eaten away eel.
Arapaima has relief and large scales. It is tightly set, striking in elasticity. Its module is 10 times greater than that of the bone.
Arapaima eats bottom fish, because it itself is kept at the bottom. If a predator floats to the surface, it can even swallow a bird flying over water.
Burbot
It feeds on gudgeons, ruffs, young fish of various fish, including its own species. The moving mustache on the burbot's head lures the prey. He himself hides in silt or under the snag, in the deepening of the bottom. U sticks out like a worm. They want to eat it, but in the end, they themselves are eaten.
Burbot is included in predatory fish lakesand rivers. Ponds with cool, clear water are selected. There, burbots reach a length of 1.2 meters. The weight of the fish can reach 30 kilos.
Ruff
They are marine. In salty waters, fish of the family reach 30 centimeters in length. Four varieties of river ruffs stretch a maximum of 15 centimeters. This size is enough to feed on the larvae of aquatic insects, caviar of other fish.
Ruffles find food in shaded, bottom areas of water bodies. True, there hunters await the burbots that feed on them. What a predatory fishwins the battle - a rhetorical question.
Gustera
Reminds the scavenger, but leads a flock of life. In addition, the silver bream has silver scales, but on the keel it is not behind the fins.
Young hustlers eat zooplankton. As fish mature, they move to the diet from mollusks. Algae and underwater parts of terrestrial plants supplement them.
Saltwater Predatory Fish
Moray eels
These predatory sea fishthere are more than 200 species. The closest relatives are eels. However, they are found in fresh water. Externally, moray eels are serpentine. Fish of the family are elongated, slightly flattened laterally.
To the tail, the body narrows like a leech. The fin on the back of the fish stretches from the head to the end of the body. Other fins are absent. The minimum length of a moray eel is 60 centimeters. Representatives of the giant species are stretched by almost 4 meters, while weighing about 40 kilograms.
An elongated moray head with a vicious expression of eyes and an ajar mouth is equipped with rows of sharp teeth. The mouth is open for breathing. The body of moray eels is usually hidden in crevices between stones, corals. It is difficult to move the gills there, there is no influx of oxygen.
Acne
There are 180 species in the seas. Unlike moray eels, blackheads are solid. The bodies of relatives are mottled with patterns. More acne is less aggressive. Moray eels sometimes attack even people. In ancient Rome, by the way, delinquent slaves were sometimes thrown into pools with sea fish.
Like moray eels, eels have tail, back, and anal fins. In this case, there are individual pectoral. They, like the whole eel body, are covered with mucus. The fish are deprived of scales. However, moray eels do not have body plates either.
Barracuda
It is represented by 27 species. They are called tigers of the ocean. The nickname is associated with the ferocity of the fish. She, like moray eels, attacks even people. About 100 cases are recorded per year. Half of the victims die from wounds. So, barracuda can be safely written in the most predatory fishthe ocean.
Outwardly resembles a pike, but it does not have a kinship with it. The ocean predator belongs to perch-shaped ray-finned fish. The length of the barracuda rarely exceeds a meter. The standard weight of the animal is 10 kilograms.
It seems that a predator of this size can hardly harm a person. However, barracudas are schooling fish and also attack together.
Toad fish
Belong to the family of the battrachs. There are 5 species of toad fish in the oceans. The name was given to them for a large and wide head, as if flattened from above, a wide mouth, a protruding lower jaw, round eyes on a roll out, as if wrinkled gray or brown-green skin.
The length of the genus does not exceed 35 centimeters. The skin of fish, like that of ordinary toads, is naked, devoid of scales.
The color of the toad fish can change, adapting to the colors of the environment, the bottom. It does species of predatory fishespecially dangerous. You can not notice the toad in shallow water, step on, offend. Meanwhile, on the body of fish there are poisonous outgrowths. For a person, her injection is fatal. However, irritation, pain and swelling at the site of the poison are pronounced.
Sharks
There are more than 400 species in the seas and oceans. Representatives of some do not exceed 20 centimeters in length, while others stretch for 20 meters. Such, for example, is a whale shark.
In the generally accepted sense, it is not a predator, eating zooplankton. A typical predator is a white shark reaching a length of 6 meters.
All have common features. These are: a cartilaginous skeleton, the absence of a swimming bladder, an excellent sense of smell, which allows you to smell blood for 5-6 kilometers. Still, all sharks have gill slits and breathe oxygen, have a streamlined body shape. The latter is covered with scales, has embossed protrusions.
Needle fish
She also has a freshwater variety. She lives in reservoirs of India, Burma. Like most marine, the freshwater needle is small, reaches a maximum length of 38 centimeters.
With such a length, a real body weight of several hundred grams is real. However, the body of the needle is so thin that it weighs several times less. Therefore, fish is rarely used for food - there is little "broth".
The closest relatives of needle fish are seahorses. However, they have a normal color spine. The bones of the needles are greenish. This is not due to toxicity. Green color gives a harmless pigment biliverdin.
Arrow fish
From these distant relatives of the needles you can get a solid fat. Large representatives of the genus gain 6 kg. Arrows are systematically classified as sargan, that is, they are close in blood to flying fish.
If the needles can only encroach on crustaceans and newborn fry of other small fish, arrows grab a gerbil, sprat, young mackerel. Eating barbecue and gerbil. Needles in the diet of arrows, by the way, are also included.
Sea devils
Photo of predatory fishrepresents almost 10 types of devils. All of them are as if pressed down from above, that is, low and wide. To the tail, the body narrows sharply. The first two thirds of the length of the line is occupied by the head. Therefore, in general, the body of the fish is like a triangle spread out along the bottom.
Mouth fish with a snack. The protruding lower jaw is equipped with sharp teeth. They are bent inside the mouth. On the upper jaw there are the same. The mouth swings open like a snake. This allows the devils to swallow superior prey.
Representatives of large species of marine devils reach a length of 2 meters. At the same time, about half a meter falls on the outgrowth with a luminous capsule at the end. A flashlight is located on the face of the devil and attracts prey. The devil himself disguises himself at the bottom, burrowing into silt, sand.
Only the lamp remains. As soon as the prey touches him, the devil swallows. By the way, fluorescent bacteria glow.
Catfish
These are eel-like fish, live only in the seas. Catfish are systematically classified as perch. Predatory fish bite- a rarity, because the animal is deep, falls to 400-1200 meters. This is partly due to the love of catfish for cold water. Its temperature should be below 5 degrees.
A catfish can swim to the surface only in pursuit of prey. However, its predator usually finds itself in the depths, eating jellyfish, crabs, starfish, and other fish.
In them, the animal bites with sharp, like knives, teeth. Among them there are pronounced fangs. Therefore, catfish are also called sea wolf.
Lufar
Not divided into varieties. In the Luffarev family, there is one genus with a single species of perch-like fish. In length, they can exceed a meter. The maximum mass of bluefish is 15 kilos.
On the back of a flattened body, the bluefish has fins with cartilaginous rays. The tail fin of the fish resembles a fork in shape. In place and thoracic, abdominal outgrowths. They, like the whole body of bluefish, are painted in blue. It has an admixture of green. The back is many times darker than the abdomen.
Eel-pout
It has several subspecies. The most common of these is ordinary or European. There is also an American, eastern eel. Fishing predatory fishunpopular due to the repulsive appearance of the animal.
The venomous body of gray-green color is covered with small scales. The skin of the eel is thick and rough. A freshwater burbot has a similar appearance.
Like burbot, the eel loves cool waters. At the same time, the fish keeps in shallow water, off the coast of the seas. Water warms there more than at depths. Therefore, the eel chooses cold seas, eating mollusks, crustaceans, caviar, and fry in them.
Passing predatory fish
Sturgeon
Like all migratory fish, part of life swims in the sea, and the other in rivers. The group includes about 20 species. Among them: Kaluga, Siberian and Russian sturgeons, shovel, Beluga, stellate sturgeon, sterlet, spike. All of them are cartilaginous, have no bones, which indicates an ancient origin.
Sturgeon skeletons are found in sediments of the Cretaceous period. Accordingly, fish lived another 70 million years ago.
The largest of the sturgeons caught weighed about 800 kilograms. This is with an 8-meter body length. The standard is about 2 meters.
Salmon
The family is represented by salmon, pink salmon, whitefish, coho salmon, whitefish or, as it is also called, nelma. They resemble grayling fish, but have a shortened fin on the back. It has 10-16 rays. From whitefish, on which salmon are also similar, the latter are distinguished by a brighter color.
Salmon fish are widespread and variable. The last term means different nuances in the appearance of one species, but in different territories. Hence the confusion of classifications.
One name can be given in different countries by 2-3 salmon. It happens, and vice versa, when about 10 names in one species.
Gobies
They belong to the percussion order. It includes 1359 species of fish. About 30 of them live in reservoirs of Russia. All of them are bottom, kept off the coast. There are freshwater, marine and migratory gobies.
However, all members of the genus are tolerant to waters of different salinity. From the shores of the seas, the gobies move to the rivers flowing into them and do not always return. Freshwater species can also move for permanent residence in the sea. Therefore, the calves are called semi-passage.
The diet of gobies includes groundworms, mollusks, crustaceans, and small fish. The smallest predators do not exceed 2.5 centimeters in length. The largest bulls grow up to 40 centimeters.
Bream
His name is included in names of predatory fish, as the representative of cyprinids feeds on bloodworms, plankton and other crustaceans, invertebrates.
Interestingly, semi-aisle bream live about 8 years less than freshwater bream. The last century is about 20 years. The same can be said about other semi-passage cyprinids, for example, carp or roach.
Most predatory fish are concentrated in the warm, marine waters of the tropics. In cool and fresh reservoirs, herbivorous species are more common.
