The most terrible inhabitants of Russian water bodies
It is considered that only the southern tropical sea full of dangerous for human beings and there only should be used with caution. However, in the Russian moderate climate meet the inhabitants of the waters, meeting with which should be avoided. One danger ascribes only a popular rumor, but with other really better not to meet.
The great raft spider, or the spider-hunter (Dolomedes plantarius), living along the banks of rivers, lakes and swamps is actually on the verge of extinction, so meeting with him is unlikely. In Russia, the spread of Western-Palearctic species of this family of spiders, mainly living in the Samara region and the Republic of Karelia. The size of females plantarius can reach 25 mm. the Spiders are hunters able to dive and move quickly through the water. They feed mainly on insects, but can attack young fish and tadpoles. For humans the bite of plantaris painful, the pain may persist for several weeks, but a lethal danger to humans, the spider is not.
Folk people call the hair-worm, that live in open water, Russia, horsehair, living in water and capable of penetrating the human body, usually through the heel, while bathing. Once under the skin, horsehair allegedly moving towards the heart, causing unbearable pain and itching of the skin. Remove it from telecities impossible. Actually for a person hair quite harmless: these worms are indeed parasites, but their hosts are insects. The larvae of a Gordian worm invades the body of a large insect, where they develop for about a month, and then, having turned into an adult, they gnaw their way out. Man, even if he swallows the larvae with water while bathing, hairy harm will not bring, he’s just not suited to live inside the human body. And certainly no danger does not represent adult — longhairs do not eat and not be able to “gnaw”, they completely absent of the digestive system.
JELLYFISH-THE GARDEN SPIDER
Poisonous jellyfish that live in Japan and Okhotsk seas, in the waters of the Tatar Strait. The small size of the Medusa: the dome reaches a diameter of 25-40 mm and resembles a bell with four red folds in the form of a cross, because of what jellyfish got its nickname. Stinging cells of garden spider are located on the tentacles, which can exceed the size of the jellyfish several times. Jellyfish-like trapdoor spiders, well warmed up water and prefer the shallow, muddy places and coves covered with sea grass and algae. The hot and dry summer always contributes to the increase in the number of jellyfish.
For the human encounter with the Medusa-the garden spider is not deadly, but painful. Immediately after the bite, the person feels an intense burning as if the skin touched with a hot iron. Then the affected area turns red, starts itching, rash, reduced sensitivity of the skin. After ten minutes, there is a General weakness, lower back pain and joint pain, restricted breathing, uncontrollable coughing choking, nausea. The person experiences intense thirst, numbness of the extremities, in severe cases can even develop paralysis. The pressure drops, the body temperature rises. In addition, the jellyfish’s venom is a garden spider acts on the nervous system: the person comes to emotional arousal. The poison is especially dangerous for people with allergies is they can develop a semiconscious state. In such cases, without medical assistance is necessary. If pronounced symptoms, the burn should be washed with salt water or alcohol-based liquid, hide in the shade and drink plenty of fluids — it reduces the concentration of poison in the body. Generally feeling unwell lasts up to six days, but discomfort can persist for months.
The most poisonous fish of the Black sea, also known as sea Scorpion and snake on the gills and fins has spines with venomous glands. Dragons often live in shallow water and small coves with sandy-silty soil. Lying on the bottom, the predator waits its prey, uncloaked head and dorsal fin of the fish. Dragon is very difficult to see, to step on it accidentally. A shot of this fish seldom causes death, but deaths still occurred. In addition, the sea dragon venom causes severe swelling, necrosis of the affected area and extremely painful. May develop paralysis of the respiratory and hemodynamic disorders.

The injection site recommended by physicians to wash out salt water or saline solution, to remove from a wound fragments of poisonous thorns. This sea dragon can be eaten — most importantly, immediately cut off the venomous spines of this fish.
The black Scorpion, or black sea fish, inhabiting the Black sea, the Eastern Atlantic and Mediterranean, sometimes caught in the sea of Azov. Usually it is found near the shore, and randomly has a chance to deal with it. In addition, to distinguish this fish is extremely difficult, therefore, to prick of its thorns very easily. Spikes the bet, cast ashore by the waves, can even pierce through light shoes. After the injection of the poison begins to cause pain, sometimes so severe that may develop a painful shock and loss of consciousness.
