Such monster fish live not only in the depths of the ocean, but also in freshwater rivers and lakes, and even in shallow water. Therefore, when entering an unknown body of water, especially somewhere in the tropics, you should not let your guard down.

1. Pacu fish


This fish can reach one meter in length and weigh about 25 kg. Its teeth resemble human ones in shape, but if this fish bites you, you won’t think it’s enough. This monster lives in the rivers of the Amazon, but after sport fishing for this species was allowed, it spread to reservoirs North America and Asia.

In 1994, two were recorded in New Guinea deaths among fishermen. They were found completely riddled with teeth, death was due to loss of blood. It was not immediately known what kind of animal attacked the men, however, as it turned out later, it was a pacu fish.


This creature, which looks like a cross between a snake and a fish, is found in the Amazon and rivers of South America and shocks its victims with 600 volts of electricity when danger or prey appears. This discharge is quite enough to kill a person.


In appearance, this fish resembles a real monster with a terrible set of small and sharp teeth. Its weight can be 30 kg, and the length of the big-headed fish can reach 2 meters. The monster lives in the ocean and camouflages itself among the sea rocks.

When attacked, the big-headed fish opens its huge mouth and sinks its teeth into the body of the victim. The fish's mouth can fit a soccer ball, which it can easily swallow. It is unlikely that a person will be able to escape from the attack of such a sea predator; there is even a danger of being swallowed whole, since the size of the stomach of this terrifying fish is almost equal to the length of its body. There have been cases where human remains were found in the stomachs of these fish.

This is a man-eating fish, it is the main culprit in the disappearance of people on the river. The weight of a catfish can reach up to 140 kg, and it can attack even in a crowd of people.

But people themselves are to blame for the fact that the fish is addicted to human flesh, since local residents, according to ancient customs, send the half-burnt bodies of the deceased on their last journey along this river after all Indian rituals.

6. Payara fish



The payara fish or mackerel-shaped hydrolik simply amazes the boundaries of human imagination - it is a vampire fish, a real Count Dracula in the form of an aquatic inhabitant. The monster grows up to one and a half meters in length and can weigh about 14 kg. The length of its lower fangs can reach 16 cm. A payara uses his fangs, knowing exactly the location of the victim’s internal organs. Therefore, a careless person swimming in the rivers of the Amazon can receive a fatal bite from this terrifying fish. She will clearly sink her teeth straight into the heart or lung, thereby killing her victim in one go.

7. Stone fish



The wart or stone fish is one of the most poisonous fish in the world. This saltwater fish is a master of camouflage among coral reefs. She disguises herself as a stone, sprinkling herself with sand from the bottom, and waits for her prey. This fish, of course, cannot eat a person, but it can easily kill him.

Since this fish is very similar to a stone and it lives mostly in shallow water, a person can step on it, for which he will receive a dose deadly poison. The worst thing is that there is no antidote to the poison of the stone fish, and the person dies in terrible agony, since the poison does not act instantly, but over the course of several hours. This fish is common in the waters of the Pacific and Indian Oceans, as well as in the shallow waters of the Red Sea, so our tourists have a real chance to meet this monster, for example, on a popular holiday in Sharm el-Sheikh or Hurghada.

8. Snakehead fish



This dangerous predatory fish was first seen in Russia in rivers in the Far East and Primorsky Territory, as well as in Korea and China. But today snakeheads can also be found in water bodies of other countries. He is not picky about food and eats all living inhabitants of rivers, as well as amphibians.

This fish lives in the waters of the Amazon and is scary for humans due to its size, no matter how paradoxical it may sound. Vandellia feeds on flesh, and due to its size (maximum 2.5 cm in length and 3 mm in thickness) it can enter the human body through the ureter or anus and eat the flesh from the inside, bringing torment and suffering to its victim. This fish swims to the smell of blood and urine, as these are its food sources. But fortunately, such cases are very rare.

Her teeth bite into flesh as easily as a warm knife cuts through butter. These fish reach a maximum length of 30 cm, but they swim and attack in schools, and in a very short period of time, for example, only bones will remain from a cow carcass. If a school of these voracious and bloodthirsty fish attacks a person, most likely he will not be able to escape.

11. Urchinfish



This fish is notorious for being highly poisonous, containing colossal amounts of tetrodotoxin in its skin, intestines and ovaries. This substance, entering the victim’s body, affects the brain, causing paralysis and then death. Therefore, it is better not to eat this fish.

But it is prepared by professionals who have spent many years learning how to properly cut fugu so that the poison does not poison the meat. But without experience, you can serve death to a person on a platter along with fish.

12. Saw-nosed stingray



The huge saw-nosed stingray is dangerous with its long nose, on the sides of which there are razor-sharp processes. A seven-meter stingray will not just attack a person, but it has a heightened sense of territorial defense and very poor eyesight, so if a person is in the wrong place at the wrong time, the stingray will launch its saw with all its might and turn its victim into mincemeat . The danger also lies in the fact that this river monster is perfectly camouflaged and sometimes it can be noticed too late. However, this species is under threat of extinction due to human activities poisoning the environment.

13. Guasa fish



Compared to guasa fish, all other representatives are just small fish. It is not for nothing that Guasa is called the “Atlantic giant gooper”, because its size is terrifying. This fish weighs about 450 kg, and its mouth can be up to 5 m long. This specimen is the same as a large one White shark or a giant catfish, can completely swallow a person in one go.

What fish in the world are considered the most dangerous? Of course, the most common fear is sharks, then perhaps piranhas. As a rule, this is where the list of “popular” fish ends, leaving out many interesting candidates for the monsters of the waters. But in fact, there are many more killer fish than we can imagine, fortunately, almost all of them are found in places where it would never occur to a person to take water baths.

If a predatory fish reaches a size of a couple of meters, then you should stay away from it - even if its diet does not usually include human meat. This simple truth, alas, is not accessible to everyone, and yet another catfish ends up being classified as a “killer fish.” As well as stingray, anglerfish, snakehead and many others. So let's get started with our heroes today.

Saw-saw stingrays (lat. Pristidae)

These huge creatures can reach a length of 7 meters and weigh more than 2500 kg!

Brown pacu (lat. Colossoma macropomum)

Brown pacu are found in the fresh waters of South America. Externally, the fish is very similar to a piranha, and for good reason, since it is its distant relative.

However, unlike piranhas, brown pacu can reach a height of about a meter and weigh about 40 kilograms. A special feature of this species is its teeth, which are surprisingly similar to human ones. Thanks to their powerful jaws, pacu can kill almost any creature caught in the water. But it is worth noting that they rarely attack a person without a reason.

Olive catfish (lat. Pylodictis olivaris)

Well, who is afraid of catfish? This fish is often caught by people in order to decorate our table.

But olive catfish, despite the harmless name, are quite large freshwater fish, growing up to one and a half meters in length and reaching a mass of 60 kg. These catfish are actually caught for food, but due to their large size, such fish become a deadly enemy for humans. There are cases when people became dinner for her.

Mackerel-shaped hydrolytics (lat.Hydrolycus scomberoides)

Another name for this fish is payar. This species also lives in South America, in particular in the fresh waters of Venezuela.

Their distinguishing feature- huge fangs up to 15 cm in length and insatiable gluttony. Mackerel-like hydrolics easily destroy and eat piranhas and animals that fall into the water. The fish is aggressive, but rarely attacks people. However, there are people who paid with their lives for the sake of their interest in fish.

Wallago attu catfish

These catfish live in the waters of Asia, India and Afghanistan.

They are larger in size than even olive catfish, and from time to time they like to attack swimmers who decide to swim in untested lakes. That is why it is not recommended to relax near untested sources of water, and especially to swim in them.

European anglerfish (lat. Lophius piscatorius)

Another name for this fish is monkfish, it reaches two meters in length and weighs 60 kg.

Very often caught for sale and personal consumption. This sluggish fish is a master of camouflage and feeds mainly on other fish. They live on the bottom, lying in ambush and lying in wait for passing fish. However, to come into view monkfish we don't recommend it. Few people will be able to escape unharmed from the terrible jaws.

Atlantic giant groupers (lat. Epinephelus itajara)

The giant grouper or guas is a sea fish from the rock perch family; this representative of waterfowl is really very interesting.

Essentially, a grouper is a huge ocean-dwelling bass that can weigh up to 200 kilograms. Many divers love to be photographed next to a huge grouper, but the fish themselves rarely like it, so many risk-takers have a powerful reminder of their fateful underwater encounter on their bodies. And some people could not survive after meeting with ocean perch.

Surgeon fish (lat. Acanthuridae)

Surgicals are usually fairly small ray-finned fish that live in tropical waters, although there are species that grow up to a meter in length.

They do not have terrible teeth or poisonous spines. However, their tail fins are razor-sharp and can easily cut you. It is strongly recommended not to swim in the water where these wonderful creatures live, as recovery will be long and painful.

Tiger fish Goliath (lat. Hydrocynus goliath)

This fish is no safer than a shark, and its character is as unbearable as that of piranhas. This is one of the most dangerous freshwater fish in the world, which has huge, sharp teeth. The most major representatives Goliaths are found in the Congo River.

Brown snakeheads (lat. Channa micropeltes)
