ABSTRACT 

The article contains information about specific characteristics of fish, predatory fish and their species. 

KEYWORDS 

Fish, predatory fish, structure, lifestyle, ecological characteristics. 

INTRODUCTION

Fish (Pisces) is a large class of the vertebrate subtype, 

very common. The structure, life and ecological 

characteristics are very well adapted to the aquatic 

environment. The ancient ancestors of fishes were 

chordates with a simple lanceolate structure. In the 

course of historical development, animals with pairs of 

fins appeared from the first chordates. They lived a 

wild life. As a result of living an active life in search of 

prey, their nervous system and sensory organs 

developed and fishes appeared. Fish are chordate 

animals that live in water. The body is compressed 

from both sides, covered with scales, has three odd, 

two pairs of fins. He breathes through Jabra. The heart 

has two chambers, the circulatory system consists of 

one circle, and the nervous system consists of the brain 

and spinal cord. Fish sense organs consist of eyes, ears, 

nose, whiskers and side stripes. A fish cannot see far. 

He sees things a meter away. But due to the shrinking 

of the sickle cell, he can see up to 12 meters away. The 

hearing organ of fish consists of the inner ear. Because 

the water is in a dense environment, fish hear very well. 

He can even hear footsteps on the shore. Like all 

animals, he has a strong sense of smell. Some fish also 

have whiskers. A mustache acts as an emotion. The

lateral lines consist of nerve cells. Through the lateral 

lines, the obstacles in front, the moving prey are easily 

sensed. If the fish becomes blind, it can easily live 

through the side lines. 

Predatory fish. Predators of the underwater world 

include fish, their diet includes other inhabitants of 

water bodies, as well as birds and some animals. The 

world of predatory fish is diverse: from scary 

specimens to attractive aquarium specimens. They 

combine their large mouth with sharp teeth to catch 

prey. 

A characteristic feature of predators is unrestrained 

greed, excessive satiety. Ichthyologists note the 

special intelligence and inventiveness of these 

creatures of nature. The struggle for survival 

contributed to the development of abilities predatory 

fish surpass even cats and dogs. 

Sea predatory fish. Most of the marine fish of 

predatory families live in the tropics and subtropics. It 

is in these climatic zones that there are many different 

herbivorous fish, warm-blooded mammals that make 

up the diet of predators. 

Shark. Takes implicit leadership white predatory fish is 

the trickiest for people. The length of the carcass is 11 

m. Its 250 species of relatives can also be dangerous, 

but the attacks of 29 representatives of their families 

have been officially recorded. The safest is the whale 

shark - huge, up to 15 m long, feeds on plankton. 

than 1.5-2 meters are tricky and dangerous. Among 

them: 

• Tiger shark; 

• hammerhead shark (there are large protrusions 

with eyes on the head of the side); 

• shark mako; 

• katran (sea dog); 

• gray shark; 

• spotted shark scillium. 

In addition to sharp teeth, fish are equipped with 

barbed spines and tough skin. Cuts and blows are as 

dangerous as bites. Injuries caused by large sharks are 

fatal in 80% of cases. The power of the jaws of 

predators reaches 18 tf. With a bite, it is able to 

dismember a person. 

The unique abilities of sharks allow them to catch the 

water vibrations of a swimming person at a distance of 

200 m. The inner ear is tuned to infrared and low 

frequencies. The beast senses a drop of blood at a 

distance of 1-4 km. Vision is 10 times sharper than 

humans. The speed of acceleration behind the beast 

reaches 50 km per hour. 

Moray. They live in underwater caves, hide in thick 

vegetation, coral reefs. The length of the body reaches 

3 meters with a thickness of 30 cm. The grip of lightning 

is so strong that cases of the death of divers who were 

not freed from a fatal encounter are described. 

Aquarians are familiar with the comparison between 

moray eels and bulldogs. 

Its scaleless body resembles a snake, which makes it 

easy to hide. The body is much larger than the back. A 

big head with a huge mouth that barely closes.

Servi 

Moray snakes attack larger victims. It grabs the prey 

with its tail and helps break it up. The ability to see the 

prey is poor, but the instinct compensates for the 

deficiency in chasing the prey. 

Barracuda (seiren). The length of this population, 

similar to large peaks, it reaches 3 meters. The lower 

jaw of the fish is pushed forward, which makes it 

especially scary. Silver barracudas are sensitive to 

bright objects and water vibrations. Large predatory 

fish can bite a diver's leg or cause injuries that are 

difficult to heal. Sometimes these attacks involve 

sharks. 

Barracudas are nicknamed sea tigers for their sudden 

attacks and sharp teeth. They feed on everything, 

ignoring even poisonous people. Gradually, toxins 

accumulate in the muscles, making fish meat 

unhealthy. Small barracudas hunt in schools, large - 

singly. 

Swordfish. A sea predator with a length of up to 3 

meters and a weight of 400-450 kg. The unique 

appearance of the fish is reflected in the name of the 

fish. The long growth of the upper jaw bone resembles 

a military weapon in its structure. A type of sword up 

to 1.5 meters long. The fish itself looks like a torpedo. 

A swordsman's punch is more than 4 tons. It easily 

penetrates a 40 cm thick oak board and a 2.5 cm thick 

metal sheet. The beast has no scales. Despite its water 

resistance, the travel speed is up to 130 km/h. This is a 

unique indicator that raises questions even among 

ichthyologists. 

The swordsman swallows the prey whole or cuts it into 

pieces. There are many fish in the diet, including even 

sharks. 

Monkfish (European monkfish) 

The resident at the bottom expands. It got its name 

because of its unpleasant appearance. The body is 

large, about 2 meters long, weighing up to 20 kg. 

Noteworthy is the crescent-shaped mouth with an 

extended lower half-jaw and close-set eyes. 

Natural camouflage reliably camouflages the predator 

during hunting. A long fin on the upper jaw serves as a 

fish catch. In its formation, bacteria live as bait for fish. 

The angler must watch for prey near his mouth. 

Monkfish can swallow prey several times larger than 

itself. Sometimes it rises to the surface of the water 

and catches birds that have fallen to sea level. 

Sargan (arrowhead fish). In appearance, teaching sea 

fish can easily be confused with needle fish or 

embroidery. The silver body is 90 cm long. Sargan lives 

near the water level of the southern and northern seas. 

Long, narrow jaws protrude forward. The teeth are 

small and sharp. 

It feeds on sprat, mackerel, gerbil. In pursuit of the 

victim, it quickly jumps through the water. A 

noteworthy feature of the fish is the green color of the 

bones. 

Night. A large school predator common in the Atlantic 

Ocean. Carcass reaches 4 meters, weighs half a ton. 

The spindle-shaped body is adapted for long and fast 

movement up to 90 km / h. The diet of predators

includes mackerel, sardines, types of molluscs, 

crustaceans. French nicknamed tuna sea calf for its red 

meat and taste similarity. 

Pelamida. The appearance is similar to tuna, but the 

size of the fish is much smaller. The length does not 

exceed 85 cm, the weight is 7 kg. Slanted strokes on 

the back, highlighted in blue. The abdomen is light. 

Schools of bonito are closer to the water surface and 

feed on small prey: anchovies, sardines. 

Predatory sea fish are characterized by unusual 

hunger. Up to 70 small fish were found in one person. 

A lot of work is being done to develop the field of 

ichthyology in Uzbekistan. Many decisions have been 

made about fish breeding. Our young ichthyologists 

are returning after training abroad. However, at 

present, the fauna of our country has not been fully 

studied. For this reason, we can know how many fish 

species exist in our country and how many of them are 

endangered based on the scientific work carried out by 

our scientists.
