    Spiders from ancient times live on our planet, they live in different parts of the world and are found everywhere. Some species of spiders are harmless and even beneficial, destroying harmful insects. But on the Earth live very dangerous poisonous spiders.

    All spiders are predators, they feed on insects, small animals, birds, only one species of spiders - a spider, a horse, feeds on the leaves of acacias. Many spiders for hunting use cobwebs, weave networks into which insects enter.

    Brazilian wandering spider

    The most poisonous spider in the world is the Brazilian wandering spider. This dangerous spider inhabits the tropical and subtropical regions of America. He does not weave cobwebs and does not live in one place, but prefers to move in search of food.



    Often this spider enters a person's home, hides in clothes, in boxes with things or with food, gets into places where people store bananas, because they prefer to eat bananas - hence its other name is banana spider. But the main food is still insects, does not disdain spider and birds, lizards, hunts even on those animals that are larger than it.


    There are two types of Brazilian wandering spiders - jumping and running spiders. Running spiders lead a nocturnal life, and during the day they prefer to hide under rocks, driftwood, in crevices of foundations, in houses or in people's barns. These spiders run very fast.

    The Brazilian wandering spider has a small size of about 10 cm, but the bite of this spider is extremely dangerous, since the spider secretes a toxic poison that causes serious allergic reactions. Especially dangerous are spider bites for weakened, sick people and small children. To avoid death, a person who suffers from a bite should be provided with urgent medical assistance.

    Six-Eyed Sand Spiderman

    Six-Eyed Sand Spider is considered one of the most dangerous spiders on Earth. This spider lives in the sandy areas of South Africa and South America. He lives in the sand dunes, hiding under snags or in the roots of trees, under rocks. He does not weave cobwebs, but hunts, burying himself in the sand and waiting for his victim in ambush.



    People prefer not to attack people, but if a person still meets a six-eyed sand spider and the spider bites him, then this meeting can end for a person fatal. The poison of this spider is not inferior to the toxicity of the poison of the Brazilian wandering spider. The toxin contained in the poison causes a rupture of the walls of the blood vessels, which leads to severe internal bleeding. Antidote from the bite of the six-eyed sand spider does not exist.

    Spider sizes are not large, body length is from 8 to 15 mm, and with a swing of thin legs - 50 mm. The sand spider has six eyes, unlike most species of other spiders, which have eight eyes, hence the name is six-eyed. Coloration depends on the habitat and can be different, from pale yellowish brown to reddish-brown.

    The spider feeds on small insects, scorpions. Hiding in the sand, in this position can be a long time, waiting for its prey. Being in ambush, the spider feels the vibration from the movement of even the smallest insect and when the insect approaches, it attacks, injecting its poison into the victim. The insect dies instantly, the spider begins to dine. A well-fed spider can do without food for almost a year. Six-eyed sand spider - a long-liver, the duration of his life can be up to 15 years.

    Sydney leukopause or sparrow spider

    Sydney funnel spider is also one of the most poisonous spiders that inhabit our planet. These spiders are found on the Australian continent, they once met only in the vicinity of Sydney, but eventually spread to other areas of the Australian continent, found in Queensland between the cities of Brisbane and Gimpi, as well as on the island of Fraser.



    The body length of the spider is from 2 to 5 cm, and together with the feet - 7 cm, males are smaller than females and have thinner and longer limbs. The spider looks shiny and smooth, since there are no hairs on the body, the color is black to brown, and the spinning organs are clearly visible on the spider's belly.

    Spiders build themselves holes with tunnels and several entrances, the length of the burrow can reach 40 cm. The entrance to the mink from the inside is covered with cobwebs and resembles a funnel. Hence the name of the spider. The funnel spider prefers to build burrows in loose soil in the garden, on golf courses, between curbs, in flower pots, in doorways.

    Female spider is not dangerous, as it is constantly in the hole, but the males during the mating season leave their holes in search of the female and penetrate into the dwelling of a man, in sheds, climb into shoes, into boxes.

    Before the bite, the spider stands in a pose, raising its paws and demonstrating its long fangs, then lightning attacks, causing several bites. The spider's fangs lightly bite through not only the skin, but also the nail plates.



    A male bite can cause harm to a person, toxins found in spider venom lead to damage to the nervous system. At the site of the bite, twitching of muscles is observed, then there is numbness of the limbs, tongue, lips, abundant secretion of tears and saliva, dyspnea appears and coma sets in. If you do not enter the antidote on time, a lethal outcome is possible, especially the bites of a funnel spider for children.

    The bite of a male and a young female does not pose a threat to humans and animals, as it can not bite the skin, but the bite of an adult female of karakurt represents a great, sometimes deadly danger, since the poison of this spider is 15 times stronger than the poison of the rattlesnake.

    After the bite of this spider, burning pain quickly spreads throughout the body, the pulse becomes more frequent, there is a headache, dizziness, abdominal and lower back pain, nausea and vomiting, difficulty breathing, and muscle weakness. The bitten person becomes covered with a cold sweat, his limbs are shaking, he can hardly move, he can not stand on his feet. The blood pressure and body temperature also increase.
