It seems that many dangerous inhabitants lurk in the depths of the ocean. It's another matter when they are forced to defend themselves or their home.

Zebra fish. This fish is also called the striped lionfish, it belongs to the scorpion family. You can meet her in the coastal waters of the Red Sea, in the warm waters of the Indian and Pacific Ocean. Zebra fish are found off the coast of Australia, Japan and China. Her body is 30-40 centimeters long, painted with pink stripes. The lionfish was nicknamed because of the long fins in the form of ribbons on the back and chest. It is there, in this beauty, that poisonous needles are hidden. An injection of a lionfish leads to severe pain. From it, people can fall into a state of shock or even lose consciousness. The poisoning is very difficult, it lasts for several hours. During this time, a person experiences convulsions, the activity of his heart deteriorates. The victim must be immediately dragged ashore, otherwise he may simply drown. Although it is believed that zebra fish are capable of killing humans, such cases have not been documented in any of its habitats.

Cones. A whole family of carnivorous gastropods bears this name. Usually molluscs live in warm tropical seas, only a few of them are taken into cold waters. The cones themselves are very active, especially when in their own habitat, someone touches them. The toxic apparatus of these creatures includes a poisonous gland connected by a channel with a hard proboscis by a radula-grater. It is located near the narrow end of the shell. Clam teeth are replaced by sharp spines. Although most cones feed on marine worms, there are exceptions in this family - fishing cones and shell-eating cones. If you touch the shell, the cone quickly pushes the radula out, plunging thorns into the body. The injection is accompanied by acute pain, the person may even lose consciousness. The lesion site begins to grow numb, and other areas are lost. As a result, paralysis of the respiratory system and the entire cardiovascular system may even occur. The venom of the cone is similar in its effect to the venom of the cobra. There is a blockage of signals from the nerves to the muscles. Statistics provide impressive data - every third, and even the second case of a spike in a cone becomes fatal for a person. It is only worth noting that people themselves are the cause of unhappiness. A person is attracted by the beauty of the shell and wants to take it in hand. The cone begins to defend itself. Today, on the basis of the venom of the cone, they have even begun to produce drugs that help against epileptic seizures or simply relieve pain.

Cyanea is hairy. Don't you like jellyfish? Meet cyanea - the world's largest jellyfish. It lives in all northern waters of the Pacific and Atlantic oceans and can be found close to the surface in coastal waters. In October 1997, an individual with an umbrella diameter of 74-76 centimeters was caught in the Peter the Great Bay. And on the east coast of the United States, the famous zoologist Louis Agissitz in the last century caught a jellyfish, whose dome diameter was 2.2 meters. But another record got into the Guinness Book of Records - the maximum diameter of the umbrella was 2.28 meters, and the length of the tentacles was 36.5 meters! In the jellyfish, the umbrella is supplied with strong muscles, while the muscles have a brown or matte color with a red or brown tint. The main part of the body is colored red with a brick or crimson tint. Tentacles descend from the edges of the umbrella; they eventually form a continuous curtain. Cyanei are predatory creatures. Their long and numerous tentacles have many stinging cells. Medusa can shoot them, as a result, a strong poison enters the victim's body. He is able to kill small animals, causing severe damage even to large creatures.

Scorpion. This fish, better known to us as the sea ruff, gave its name to a rather large family of scorpion fish. It lives in the seas that join the Mediterranean, as well as in itself, as well as in the Atlantic Ocean off the coast of Africa and Europe. Scorpena prefers coastal waters, where it likes to hide in seaweed and just lie on the bottom waiting for prey. One has only to some careless fish or large crayfish swim up to the fish at a distance of 10-15 centimeters, as it makes a sharp jerk, opening its mouth wide. Along with the flow of water, prey also gets there. For this, the scorpion fish is well disguised - it has skin outgrowths on the head and a variegated color with dark spots on the body. The ruff goes through a molt every month. The top layer of skin is shed, like a snake. The scorpion fish meets the enemy with its thorns. The injections of this fish are quite dangerous for humans, they are very painful. In addition, an infection often gets into the wounds. The area around the injection begins to hurt and swell, the temperature rises.

Box jellyfish. This animal belongs to the class of creepers. Cubomedusa lives off the coast of northern Australia and Indonesia. The creature was infamous for its ability to inflict severe burns. All tentacles of the jellyfish are covered with stinging cells containing strong poison. The burns inflicted are very painful, the power of the poison is such that it can kill 60 adults in three minutes. Scientists estimate that the box jellyfish has killed at least one hundred people over the past century. This became the basis for the widespread opinion that this is the most dangerous and poisonous jellyfish in the world's waters, and maybe in general the most dangerous animal in the world. In those places where the box jellyfish lives, they erect special mesh fences that protect the bathers. Dangerous creatures cannot penetrate people through small cells.

Blowfish. This fish of the pufferfish family is better known as puffer fish, dog fish or ball fish. It contains the strong poison tetrodotoxin. The blowfish is usually found in the warm seas of the tropics and subtropics. When the situation near the fish makes it dangerous, it can increase in size by 2-3 times. Moreover, such a skill does not at all depend on the environment in which she lives. Indeed, there are special bags in the abdominal cavity that can collect both water and air. The nickname dogfish, like the puffer, she received for her unusual teeth structure. They fused together, making up four strong plates. They are so strong that the puffer easily hides the shells of crabs and mollusks with their help, getting their food. The poison tetrodotoxin is found in the internal organs of fish, its main part is in the liver and caviar, as well as in the gallbladder and skin. As a result, the caviar and liver of fish cannot be eaten at all, but the rest of the body requires careful and special preliminary processing. If the poison remains, it blocks the sodium channels of the nerve cell membranes. The muscles will quickly become paralyzed, and breathing will stop. To prepare fugu, all chefs must be licensed. Despite this, several people die every year from poisoning with an improperly prepared dish.

Wart. In the wart family, there is a carnivorous stone fish, on the back of which poisonous thorns are located. Of all the poisonous fish, this is the most dangerous. The usual size of a wart is 20-40 centimeters. She leads a sedentary lifestyle, preferring coastal waters. Dangerous fish merge with stones, it is very difficult to notice it even on land during frequent low tides. On the dorsal fin of the stone fish there are 12 thick thorns, with the help of which it injects the produced poison into the victim. A little irritation is enough for the wart to raise its spines. They are strong and sharp, which helps to easily penetrate deep into the muscle. Even bathers' shoes are not an obstacle. Within a few hours the unfortunate man loses consciousness, tormented by unbearable pain and damage to vital nerve centers. If the thorn gets into a large blood vessel, then death can occur in 2-3 hours.

Blue-ringed octopuses. This small octopus lives in tropical waters in the western Pacific Ocean and the surrounding areas of the Indian Ocean. It is very small - its length is no more than 20 centimeters, and its weight is no more than 100 grams. When an octopus is excited, it covers everything with bright blue spots. If it is calm, then outwardly it is no different from its other harmless counterparts. This mollusk, on the other hand, has a strong poison - a neurotoxin, which is produced by the salivary glands. The substance has two components, each of which is fatal in itself. The poison simultaneously affects the muscular and nervous systems, leading to paralysis of the respiratory muscles. Until recently, only the only possible means of rescuing such an octopus suffering from the poison was known. A person immediately needs to do prolonged artificial respiration.

Sea urchins. These creatures belong to the class of echinoderms. In total, there are almost 940 species of sea urchins in the world. Their bodies usually have a spherical shape, varying in diameter from 2-3 centimeters to 30. Sea urchins are covered with calcareous plates, which together form a dense shell. On it are games that are from 1-2 millimeters in length in flat hedgehogs to 25-30 centimeters in diadem. Among the hedgehogs there is even a species that has no needles at all - toxopneustes. The needles serve an important function for these creatures. With their help, sea urchins feed, defend themselves and move. In some species, the needles are also poisonous. Such sea urchins are mainly chosen by the tropics and subtropics of the Pacific, Indian and Atlantic oceans. When fragile needles enter the body, they usually break. In this case, toxins penetrate the tissues. At the moment the body is affected by the needles of a poisonous sea urchin, a person can feel severe pain. It takes only a few minutes and the temperature rises significantly on the affected area, swelling appears. The skin can lose sensitivity here, there is atony and sometimes even paralysis of the affected limb.

Stingrays. These stinging rays have a body length of up to 2.5 meters in diameter, and their weight reaches 16 kilograms. Near the very base of the tail is a large spine with jagged edges. Her injections are extremely dangerous, because there are poisonous glands in the groove. The poisonous properties of stingray have been known for a long time, even the ancient Greeks used poison from a stingray spike as an anesthetic in dental treatment. Today people come into contact with this stingray quite often. More than 3 thousand people in the world suffer from a prick of his thorn every year. True, stingrays usually prefer not to contact a person, hiding when he appears. The poisonous thorn is just a defensive weapon that is used only in case of danger. Such a stingray can count the attempts of overly curious divers to get to know it better. This is how the famous Australian TV presenter Steve Irwin, the famous crocodile hunter, died in 2006. When the film "The Most Dangerous Inhabitants of the Ocean" was filmed near the Great Barrier Reef, the presenter received a sting in the heart from a stingray. Irwin could not be saved.
