Dangerous sea creatures

Actually sharks, except for a few species, and a total of more than 250, do not attack people. Just behave and other toothy predators of the sea-giants. But we are not talking about them.

Most dangerous marine animals found among small, often inconspicuous or, conversely, very bright and colorful marine life. These completely harmless looking creatures produce the strongest, sometimes deadly poisons. Scientists count about 500 species of poisonous fishes, 93 species of venomous coelenterates animals, 91 species of mollusks, and 26 species of echinoderms. But do not succumb to fear. Poisonous marine animals affect humans, usually in self-defence when he disturbed or careless movement will hurt them.

One of the most toxic and also the ugliest of marine animals – fish-stone. It is also called bugorkami or borodavchenko. This creature with a total length of 15-20 centimeters, with an ugly big head, small eyes and a large mouth with prominent lower jaw forward. Naked, without scales, brownish-brown, sometimes with pale spots and stripes, the body of the fish-stone is covered with bumps and warts, and the dorsal fin stick out the hard poisonous spines. Usually verrucosa hiding among the coral, under rocks, buries itself in mud or sand and may remain on the shore in pools after a flood. She looks like a stone chip and painted inconspicuously, so to see her is almost impossible. If a person steps on a stonefish or accidentally touch her, she will stab him with a spiked fins, which are poisonous glands. The venom of borodavchenko extremely dangerous. There are known cases when people died within a few hours and even minutes after the shot its poisonous thorns.

The stonefish is found in the Red sea, Indian ocean, Pacific Islands and Northern Australia, whose inhabitants call it warty vampire. People who are fortunate enough to experience a twinge of borodavchenko, often remain disabled, because its venom destroys red blood cells and attacks the Central nervous system. Unlike fish stone, masters camouflage, Zebra fish or lionfish, has a highly visible appearance. The body length of 30-40 cm are painted with bright pink stripes. The main decoration lionfish – long ribbon dorsal and pectoral fins. They remind the fan of ostrich feathers or a lion’s mane. Hence another name for lionfish lion fish. But perhaps the most apt her nickname – fish-Turkey. When she is moving slowly, revealing a lace fan pectoral and caudal fins, and indeed resembles it is important procession through the poultry yard turkeys. It is in these luxurious fins lurk sharp poisonous needles. The shot of the lionfish, as borodavchenko, causes severe pain, from which people lose consciousness or fall into a state of shock.

It is believed that Zebra fish is able to kill a man, but such cases are not on record in any of the places where it lives (in the coastal waters of the red sea, the Indian ocean and in the Pacific ocean off the coast of China, Japan and Australia). To approach the lionfish is dangerous, especially on the side. Reacting to the changing situation, she turns to the troublemakers dorsal fin to manitos but strike him with a poisonous injection. Poisoning by venom of the lionfish is very hard: it is accompanied by convulsions, cardiovascular dysfunction, it happens that at the puncture site develops gangrene. Poisonous sea dragon beware the fishermen since ancient times. Shot his spines located on the dorsal fin and along the Gill slits, is no less painful and dangerous than the prick fish-Zebra. It can cause breathing problems, convulsions and even lead to heart failure. Dorsal spines from dragon is from five to seven, each of them covered with a thin layer of skin, the tip of the spike sticking out of her like a needle. Dragon found off the coast of Norway and the British Isles and further South to the Mediterranean and the North African coast. Poisonous spines sting their prey and the stingrays are known under the name of sea cat. According to statistics, in the U.S. only from their injections annually affects about 1,500 people. This happens not because the stingrays are particularly aggressive, they just have chosen to stay on the coastal waters of great waters, from the countries of Northern Europe and North America to the middle latitudes of the southern hemisphere, and there is almost always a lot of swimmers and fishermen.

Weapon sea cat – one or more sharp spines located on the tail end of plateuing. Even the small half-meter of rays inhabiting the coastal waters of the Atlantic ocean, the length of the caudal spike is 20 cm, and 3-4-metre-high ramps on the tail thickness in the human foot is 30 cm of the spike. Scat is able to strike with such force that can break tail spike the bottom of the boat.

The poison sea cat very toxic. He gets into the wound with the cloth, filling the grooves of studs, and directly affects the cardiovascular system (causing a drop in blood pressure, palpitations), poisoning accompanied by vomiting and intense sweating. Residents of the Pacific Islands, the Malays, the aborigines of Australia and Indians of South and Central America has long been produced from eagle stingrays arrowheads. On drevnegrecheskoi mythology, this is the arrow was killed by Odysseus. In West Africa, and Ceylon from a small barbed tails of stingrays made a scourge that punished the criminals, and in the Seychelles such a scourge were kept to intimidate wives. Among sea urchins belonging to the order of Echinodermata, which includes about 600 species of marine animals, some completely harmless, others is better to avoid. Poisonous urchins distributed mainly in tropical and subtropical regions of the Indian, Pacific and Atlantic oceans. Most often they affect people in the Islands of the Western Pacific.

The spherical body of the sea urchin is almost completely covered with needles. The injection causes the same pain, as stretching into the body of a red-hot nail, and, if the needle penetrates deeply, burning does not stop for several hours.

A great danger to humans are the inhabitants of coral reefs – tropical urchins of the family Vadimovich. Their body is about the size of an Apple sticking sticking out in all directions, like knitting needles 30 cm needles. They are very agile, sensitive and respond instantly to stimulation. If hedgehog suddenly falls a shadow, he immediately directs the needle toward the danger and puts them together several pieces in a sharp, hard peak. Even gloves and wetsuits do not guarantee complete protection from the fearsome rush of the sea urchin. Their injury causes acute pain, severe shortness of breath, even paralysis. Off the coast of Japan found another poisonous sea urchin – toxopneustes. The local fishermen call this urchin a murderer, because his shots are deadly. Toxopneustes somewhat larger tiaras. His body is devoid of needles, but is covered by many so called pedicellaria – flexible stems that end with something like tweezers with two or three lime leaves. When a hedgehog is calm, it “tweezers” with opened leaves slowly swaying in the water. But is careless the animal to touch them, as poisonous Capranica fire: the doors are closed, and the poison is injected into the body of the trapped victims. Toxopneustes holds it until then, until you are completely paralyzed. If the prisoner still manages to escape from the hedgehog, he carries himself tightly clinging to the body of the tweezers, which continue to compress and release in wound poison for several hours. Swimmer struck by this poison, is in danger of drowning.

In the story “the Lion’s mane” by Arthur Conan Doyle described the mysterious murder of a young teacher: “His back was cut into strips of dark purple scars, like his stroke with a whip made of thin wire. McPherson was probably tortured and killed by some kind of extremely flexible instrument, because the long, sharp scars were rounded from behind and grasped his shoulders and ribs. Chin was bleeding from the unbearable pain from his bitten lower lip”. Sherlock Holmes solved a crime. He was killed by Medusa! These sea creatures seem to be no more dangerous than foam on the crest of a wave, but among them are poisonous, tentacles kept on the body severe burns.

Poisonous refers to, for example, the Medusa Cyanea, or a Lion’s mane (the killer from the story of Conan Doyle). The campaniform diameter of the body of this giant is 2.5 metres or more, and collected in eight poisonous tentacles beams (each beam at one hundred and fifty threads) – 30 meters! Elongated tentacles of Lanei unusually resemble a beautiful crimson plume, and when they catch up and are waving, we become like the tangles or matted hair, as written by Conan Doyle, the lion’s mane. These jellyfish are widely distributed in the Northern parts of the Pacific, Atlantic and in the Baltic sea. To kill a man they hardly capable, but the touch of their tentacles can cause deep damage to the skin.

Compared to a huge jellyfish Cyanea Gonionemus little – no more than Piglet. Its dome like a bell with four red-brown folds in the form of a cross on the concave side. For this Gonionemus called krestovskom. It is found in the waters of the Pacific ocean: in the sea of Japan – Vladivostok, Olga Bay, the Tatar Strait, near the southern tip of Sakhalin, off the coast of Japan and Southern Kuril Islands. Large aggregations of Gonionemus sometimes see in Peter the Great Bay. Krestovich lives in shallow water in the thickets of sea grass. It is attached to the suction cups and the plants waiting for its prey. Burn Geniunely feels similar to a nettle sting, but unlike it entails severe disease with sharp pains in back and joints, constricted breath, dry uncontrollable cough, nausea, strong thirst, numbness of arms and legs. The venom of cistovicka often even operates on the psyche, then the patient falls into a state of extreme nervous excitement, depression. Bad feeling usually lasts 4-6 days, but another month can resume pain and discomfort.
