It seems that in the depths of the ocean many dangerous inhabitants hide. Meanwhile, the danger of most of them is a very conventional concept. They do harm only to those who disturb or attack them. Usually, if such creatures are deliberately not touched, then they do not carry danger. Another thing is when they are forced to defend themselves or their homes.
This fish is also called a striped fowl, it belongs to the family of scorpion. You can meet her in the coastal waters of the Red Sea, in the warm waters of the Indian and Pacific. Fish zebra is found off the coast of Australia, Japan and China. Its body is 30-40 centimeters in length, painted with pink stripes. Krylatkoy fish was nicknamed because of the long fins in the form of ribbons on the back and chest. It is there, in this beauty, and hide the poisonous needles. A fistula injection leads to the appearance of severe pain. From it people can fall into a state of shock or even lose consciousness. Poisoning is very difficult, it lasts for several hours. During this time a person experiences convulsions, the activity of his heart worsens. The victim must immediately be pulled ashore, otherwise he may simply drown. Although it is believed that zebra fish are able to kill a person, no such cases have been documented in any of its habitats.
This name has a whole family of carnivorous gastropods. Usually mollusks live in warm tropical seas, only some of them get into cold water. The cones themselves are very active, especially when someone touches them in their own habitat. The toxic apparatus of these creatures includes a poisonous gland connected by a channel with a solid proboscis radula-grater. That is located near the narrow end of the shell. Teeth mollusk replace sharp spines. Although most cones feed on marine worms, there are exceptions in this family – cones-fishers and cone-molluscids. If you touch the sink, the cone quickly raises the radula, thrusting the spikes into the body. The prick is accompanied by acute pain, a person may even lose consciousness. The place of defeat begins to grow numb, and the sensitivity of other sites is lost. As a result, even paralysis of the respiratory system and the entire cardiovascular system may occur. The venom of the cone is similar in its effect to the cobra venom. There is a blockage of the receipt of signals from the nerves to the muscles. Statistics give impressive data – every third, and then the second case of a prick with a spike cone becomes fatal for a person. It is only worth noting that people themselves are the cause of unhappiness. A person is attracted to the beauty of a shell and wants to take it in hand. The cone begins to defend itself. Today, on the basis of the venom of the cone, even drugs have been released that help against epileptic seizures or simply anesthetize.
Do not you like jellyfish? Meet the cyanide – the world’s largest jellyfish. It lives in all the northern waters of the Pacific and Atlantic Oceans, it can be found close to the surface in the coastal waters. In October 1997, a specimen with an umbrella diameter of 74-76 centimeters was caught in the Peter the Great Bay. And on the east coast of the US, the famous zoologist Luis Agisitsz in the last century caught a jellyfish, the diameter of the dome was 2.2 meters. But the Guinness Book of Records hit another record – 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 provided with strong muscles, while the muscles have a brown or matt color with a red or brown hue. The main part of the body is painted red with a brick or crimson hue. From the edges of the umbrella descend tentacles, they eventually form a solid veil. Cynae are predatory creatures. On their long and numerous tentacles, there are many stinging cells. The jellyfish can shoot them, as a result, a strong poison enters the victim’s body. Small animals, he is able to kill, causing severe damage even to large creatures.
This fish, better known to us as the sea ruff, gave the name to a rather large family of scorpion. It lives in the seas, which apply to the Mediterranean, as well as in itself, and also in the Atlantic Ocean off the coast of Africa and Europe. Scorpena prefers coastal waters, where she likes to hide in algae and just lie on the bottom in anticipation of prey. It is worth only some careless fish or a large cancer to swim to the fish at a distance of 10-15 centimeters, as she makes a sharp jerk, wide open mouth. Along with the flow of water, mining also gets there. For this scorpion is well disguised – it has dermal outgrowths on the head and a mottled color with dark spots on the body. Every month the sea ruff passes through molting. The upper layer of the skin is then reset, like a snake. Scorpion’s enemy meets with thorns. The injections of this fish are quite dangerous for humans, they are very painful. In addition, the wound often gets infected. The place around the prick starts to ache and swell, the temperature rises.
This animal belongs to the class of crooks. Kubomeduza lives off the coasts of northern Australia and in Indonesia. Bad reputation of the creature was brought by its ability to cause severe burns. All tentacles of jellyfish are covered with stinging cells containing a strong poison. The burns are very painful, the strength of the poison is such that it can kill 60 adults in three minutes. Scientists have calculated that the cubomedusa has caused the death of at least a hundred people in the past century. This was the reason 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 kubeduza dwells, special grid barriers are placed, which protect the swimmers. Dangerous creatures through small cells can not penetrate to people.
This fish of the family of puffers is more known as fugu fish, fish-dog or fish-ball. It contains a strong poison tetrodotoxin. Bunting is usually found in the warm seas of the tropics and subtropics. When the situation near the fish causes danger to it, it can increase in size by 2-3 times. However, this skill does not depend on the environment in which it resides. After all, in the abdominal cavity there are special bags that can collect both water and air. Nicknamed the fish-dog, as well as the skaloozub, she received for her unusual device of teeth. They have grown together, having made four strong plates. They are so strong that the fugu with their help easily hides the shells of crabs and shellfish, extracting their food. The poison of tetrodotoxin is contained in the internal organs of the fish, most of it is found in the liver and caviar, as well as in the gall bladder and skin. As a result, caviar and liver of fish can not be eaten at all, but the rest of the body requires careful and special pretreatment. If the poison remains, it blocks the sodium channels of the nerve cell membranes. The muscles will quickly become paralyzed, the breath will stop. To prepare a fugue, all cooks must undergo licensing. Despite this every year, several people die from poisoning with an improperly cooked dish.
In the family of wartwatches, there is carnivorous stone fish, on the back of which are poisonous spines. Of all the poisonous fishes, this is the most dangerous. The usual size of the 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 outflows. On the dorsal fin of fish-stone there are 12 thick thorns, with the help of which it injects into the victim the produced poison. A little irritation is enough to make the wart raised its thorns. They are strong and sharp, which helps to penetrate deeply into the muscle. Even the shoes of bathers do not become an obstacle. Within a few hours, the unfortunate loses consciousness, tormented by unbearable pain and defeat of vital nerve centers.If the spine is in a large blood vessel, then death may occur after 2-3 hours. Sine-crowned octopus.
In tropical waters in the west of the Pacific Ocean and the closest zones of the Indian Ocean, this small octopus lives. It is very small – its length is not more than 20 centimeters, and the mass is not more than 100 grams. When the octopus is excited, it covers all with bright blue spots. If it is quiet, it does not outwardly differ from its other harmless brethren. This mollusk, however, has a strong poison – the neurotoxin, which is produced by the salivary glands. The substance has two components, each of which is itself deadly. The poison simultaneously affects the muscular and nervous system, leading to paralysis of the respiratory muscles. Until recently, only the only possible means of rescuing the victim from the poison of such an octopus was known. A person should immediately take prolonged artificial respiration.
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 there are games which have in length from 1-2 millimeters at flat hedgehogs up to 25-30 centimeters at diadems. Among the hedgehogs there is even a species that generally does not have needles – toxopneustes. Needles perform an important function for these creatures. With their help sea urchins eat, protect and move. In some species, needles are also poisonous. Such sea urchins basically chose the tropics and subtropics of the Pacific, Indian and Atlantic Ocean. When brittle needles penetrate the body, they usually break down. In this case, toxins enter the tissues. At the time of the defeat of the body with the needles of a poisonous sea urchin, a person can feel severe pain. It takes only a few minutes and the affected area significantly increases the temperature, there is a swelling. The skin here can lose sensitivity, there is an atony and sometimes even a paralysis of the affected limb.
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 thorn with jagged edges. The injections are extremely dangerous, because there are poisonous glands in the groove. Poisonous properties of the slope have been known for a long time, even the ancient Greeks used the poison from the spike of the tail as an anesthetic in the treatment of teeth. Today people quite often contact this slope. Every year more than 3 thousand people suffer from a prick of his thorn in the world. However, it is common for skates to prefer not to contact a person, hiding at his appearance. The poisonous spike is just a defensive weapon, which is used only in case of danger. Such a stingray can count the attempts of unnecessarily curious divers to get to know him 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 shot near the Great Barrier Reef, the presenter received a stab from the ramp directly into the heart. I could not save Irwin.
