Brazil. Animal world of Brazil

The Brazilian wandering spider has been recognized as the most venomous spider in the world by the Guinness Book of Records. He got his nickname thanks to his eternal wandering and the rejection of weaving a web in favor of endless search food.

A wandering poisonous spider never lives in one place, but always roams. It is unpleasant for a person that sometimes he enters houses. IN South America often these spiders are found in clothes or in boxes with things and food.

A wandering spider is found only in America, and even then most often in tropical and subtropical regions. There are two types of Brazilian stray poisonous spiders - these are jumping spiders, which pursue their prey with jerky jumps, and running spiders. The latter run very fast, but lead night image life, and during the day they sit under stones or hide in some other place, including in people's houses.

The Brazilian venomous wandering spider loves to feast on bananas, and will not miss the opportunity to climb into a box with this fruit. For his predilection, this spider received another name - banana spider. But the main food for him is still not fruits. It hunts mainly on other spiders and insects, and it also happens that it attacks birds and lizards that are larger than it.

He himself is a rather medium-sized poisonous predator - only some 10 cm. But his small size does not prevent him from being an excellent hunter and a serious problem for people, and all from the fact that he is able to release a solid dose when bitten toxic poison, which is formed at the ends of the chelicerae, in the channels of the poisonous glands.

Perhaps the venom of a wandering spider is less dangerous than that of snakes. adult healthy person it is unlikely to kill - it will only cause a serious allergic reaction, with which modern medicine able to handle quickly. But if a Brazilian venomous wandering spider bites a sick person or small child, then the poison can act faster than it arrives ambulance. Some specimens of this spider are so dangerous that the death of a person can occur within 20-30 minutes if immediate help is not provided.

Fortunately for the inhabitants of Russia, wandering spiders do not live here and are unlikely to ever appear: the climate is not quite suitable. But you still need to remember to be careful when handling these arthropods, in case you still have to meet them.

By itself, a wandering poisonous spider does not attack a person. It bites only in self-defense. But the problem is that these spiders love to hide and are very hard to spot. If you find a wandering poisonous spider, try to get it out of the house as soon as possible and look through all the boxes and cabinets to see if there is another one in them. If possible, you must be as careful as possible and in no case take it into your hands.

It is ranked among the most dangerous and poisonous spiders in the world. However, a group of Brazilian scientists found that the venom of this spider is effective in the treatment of erectile dysfunction. The scientists who discovered these properties of the deadly poison conducted experiments on rats, and the results of the tests were published in a journal called Sexual Medicine. The report provided information that the introduced spider toxin PnTx2-6 into the experimental animal caused a long erection after twenty minutes due to the release of nitric oxide in the body of the animal, which is a substance that dilates blood vessels and improves blood flow.

Habitat: tropical and subtropical regions of South America.
Type: terrestrial, also lives in trees.
Food: young spiders eat fruit flies, small crickets. Adults eat crickets and other large insects, as well as small lizards and mice.

Decoration: live plants, tree bark, fin, etc., anything that creates good hiding places.

Spiders are not very dangerous insects, but some of them pose a threat to humans because they can bite through the skin and inject a poisonous substance that causes non-fatal, but unpleasant toxic poisoning of the human body. What is it - the most dangerous spider on the planet, where does it live and how dangerous is it for people's lives?

How dangerous is a spider bite

Spider (arachnoid) - a predatory insect, which nature has endowed with a special poisonous weapon. The secret that insects secrete and then inject into their prey affects nervous system prey or contributes to the destruction of its tissues.

Even the largest and most dangerous spiders do not attack a person for no reason. They may bite only in self-defense or in case of imminent danger. By itself, the bite of a poisonous spider is not fatal, but Negative consequences this can only occur in situations where:

late rendering medical care;
the human body is weakened due to illness;
an allergic reaction to the poison is manifested;
bitten Small child or an elderly person.

According to statistics, 5% of the world's population suffers from "fear of spiders" (arachnophobia), although there are no real reasons for such a phobia, since almost all poisonous individuals live in tropical climate or deserts. However, every traveler, going to another country, must imagine what animals or insects he can meet and what to do.

Brazilian wandering spider

Opens the list of the most dangerous arachnids for humans - Brazilian wandering spider(Phoneutria - from the Greek. "Killer"). Sometimes it is also called "banana" because of the love of eating these fruits. Officially (according to the Guinness Book of Records) he is the most poisonous spider on the planet.

The poison that he injects into the victim is a powerful neurotoxin (they are 20 times more toxic than the toxin that the Black Widow secretes).

Signs of a brazilian spider bite:

problems with respiratory system sometimes leading to suffocation;
insufficient muscle control;
severe pain in the muscles and the bite site;
in men, the poison can cause many hours of erection, which causes very strong pain.

In nature, the Brazilian wandering spider lives in tropical jungle South America (most in Brazil). He spends his life wandering in search of food: he hunts other spiders, small birds and lizards. The size of his body is quite large (about 10 cm).

These spiders often live near human habitation, can hide in clothes, like to climb into fruit boxes, especially bananas. Therefore, the most frequent cases bites by them of people are found among the pickers.

Also unusual and dangerous is that brazilian spiders can travel in banana packages all over the globe. One of the most recent accidents occurred in the UK in 2016 with a man who bought fruit at a nearby supermarket and was attacked by such a spider.

Fortunately, a very effective antidote was developed several years ago, which can reduce the number of deaths after being bitten by such a spider.

Sydney leukopautinous (funnel) spider

The second most dangerous and most unpleasant bully in the spider world is the Sydney funnel-web spider. He is considered a bully because when attacking a person, this insect tries to make as many bites as possible and introduce more poison, although its effect is much weaker than other toxins.

In addition to such a persistent character, the Sydney funnel-web spider has very large fangs: long and sharp, like needles. It is believed that with such fangs he may well bite through leather shoes and human nails. Moreover, males are 6 times more poisonous than females.

Signs of a bite that develop in a person (appear after a few seconds):

muscle spasms;
strong frequent heartbeat;
confusion or loss of consciousness;
brain tumor.

Without medical attention, death can occur in 15 minutes, but an effective antidote was created in 1981, so there have been no deaths since then.

brown recluse spider

Recluse spiders are also known by various names: "Violin Spider", "Violin on the back", refer to the Loxosceles variety. Their size is only 2 cm, outwardly they are completely inconspicuous. Such insects are found in different countries, are very common in the eastern United States, where they even settle in houses local residents(in clothes or shoes), and in South America (Chile and other countries).

The venom of these spiders is a necrotic species that destroys tissues. The bite of a recluse spider can cause a condition called "loxoscelism", which in some cases is expressed in the death of tissues in the bite area and the formation of a non-healing open wound, which can even lead to amputation. Skin grafting is needed to treat such wounds.

Black Widow

The black widow is a family of spiders and a separate species of them (Latrodectus mactans), in the United States is considered the most poisonous representative of arachnoids. He became famous for the fact that females sometimes eat their partners.

The North American black widow gets its name from the color of its body, but its belly has red or orange spots. The size of the spiders is small: about 4 cm, however, they have a very toxic poison, a bite can end badly for a person.

Such spiders pose a danger to children, debilitated and elderly people, as well as allergy sufferers. Their poison causes severe muscle pain, increases blood pressure, pain in the lymph nodes, interrupted breathing, nausea and vomiting. Unpleasant symptoms can be felt for up to 7 days.

The redback spider also belongs to the black widow family and is considered an iconic spider in Australia, easily identified by the red stripe on its back. It is smaller in size than the black widow and is less common.

However, in Australia, such spiders can settle indoors, live in some areas of cities and suburbs in tropical zone climate. They have recently been seen in Japan as well.

The red-backed spider is small: females are up to 10 mm long, males are 3 mm smaller. These insects are nocturnal, hiding in old sheds or under stones, among plants. They hunt other insects and small animals (mice, birds, lizards, beetles, etc.).

The consequences of the bite of such a spider appear only after a day, and they are very toxic: acute pain and swelling of the bitten place, abdominal cramps, severe sweating. The most severe systemic condition called "latrodectism" (50% of cases) may end fatal if you do not use an antidote injection on time.

Karakurt

Karakurt is the most poisonous and most dangerous spider that lives on the territory of Russia in the Astrakhan region, in Asian and European regions and Africa. He is one of the representatives of the black widow family. Due to climatic changes, karakurts began to appear even in the suburbs.

One of the species, called the steppe widow, is black and decorated with 13 bright red spots on top. Its size is small: females are 1-2 cm long (more poisonous), males - up to 7 mm.

The most dangerous are sexually mature females of karakurt, whose poison is 15 times stronger than that of a rattlesnake. They pose a danger to some domestic animals (horses, cows, sheep are considered an exception) and people. They bite only in case of pressure, more often at night. summer time, and the bite is not painful, which is why they often do not immediately pay attention to it.

The action of the poison is manifested in muscle pain, paresthesia of the limbs, abdomen and chest. There is a strong fear of death, tears flow, a sick person cannot stand on his feet due to muscle weakness. Also, there are symptoms similar to the picture of an acute abdomen: nausea, vomiting, fever. However, convulsions and tremors of the limbs, respiratory failure, confusion, a sharp increase in pressure help to determine the exact diagnosis.

One of effective ways first aid: cauterization of the bitten place with a burning match, which acts destructively on the poison (if there is no medical assistance nearby), subsequent hospitalization is essential so that there is no death.

sand spider

The six-eyed sand spider has 8 legs and 6 eyes and lives in deserts. South Africa and western South America. Its scientific Latin name Sicarius translates to "killer". By nature, he is a hunter who waits a long time for his prey (other spiders and scorpions), buried in the sand. When prey runs past, it attacks - bites it, and within a few hours the insect or animal dies. Its size is about 5 cm, the abdomen is light brown or red-brown.

The venom of the six-eyed spider is a strong cytotoxin (similar to the effects of sulfuric acid), producing a hemolytic and necrotic effect, which means rupture of blood vessels and tissue decomposition. There are only 2 cases when such spiders have bitten people, but both are fatal.

golden spider

Spider sack, or golden spider (Cheiracanthium), has a size of only 10 mm, but is able to cause extensive necrosis (necrosis) of tissues with its bite, which is very painful. His habitats: European countries, Australia and Canada.

Outwardly small, yellow or greenish spider produces a strong cytotoxin poison. In the bite area, redness and sharp pain first appear, the place swells, gradually turning into a bubble or wound.

According to experts, it is these spiders that cause the most trouble to people compared to other types of arachnoids.

tarantulas

Tarantula spiders (Theraphosidae) are a whole family of arachnoids found in Africa, Australia and on oceanic islands in South America. These are the largest spiders (up to 20 cm), which some exotic lovers are fond of and even keep them at home in terrariums.

Tarantulas do not pose a danger to an adult, although they can cause pain in muscles and fever. However, for pets or children, the poison can be fatal.

Their bright beautiful fur is actually poisonous hairs. The spider combs hairs from the abdomen and throws them at its prey. If it comes into contact with the skin or eyes, the poison causes pain, itching, severe visual impairment.

Pecilotheria (tarantula)

This family also includes tarantulas - large hairy spiders, whose name comes from the Spanish dance tarantella. The spider has double fangs with which it pierces its prey. Tarantula is the most dangerous spider and one of the largest living in Russia (5 cm). Most famous South Russian tarantula common in the forest steppe zone Eurasia.

Due small size and the amount of poison released when bitten, the consequences for humans are not very toxic, but the poison acts on the nervous system, provoking minor convulsions and severe shortness of breath. Their toxicity is highest in July, when the females are sexually mature and mating.

mouse spider

The red-headed mouse spider is Australia's most dangerous spider, with 12 species. Its name comes from its soft, furry abdomen, and its bite is very dangerous to humans, although it is not very aggressive and often bites without the use of venom.

Nature endowed him with bright coloring: males have a red head and a gray-blue abdomen, females are black. Size - from 1 to 3.5 cm.

The poison has a neuroparalytic effect similar to that of the Sydney spider, but they live far from human settlements. A serum has long been made for their venom, acting against many funnel-web spider species.

Conclusion

The types discussed in this article poisonous spiders differ in habitats and in their toxicity. In Russia, such insects are found in the southern part of the country, in the North Caucasus and in the Crimea. Knowledge appearance and dangerous species of spiders for humans, their habitat conditions will help prevent meeting them, avoiding a bite or learning about the degree of danger to humans.

Let's talk about the Brazilian spider. He is in the top dangerous insects planets. The word wandering is added to its name, and for good reason. This spider, unlike the others, does not weave a web, but is on a constant journey, that is, it wanders.

You can meet him only in America, where he lives not only in the tropics, but can often be a resident of houses and outbuildings. Why is it special and what threat does it pose to a person?

The killer spider (phoneutria) is a very fast and aggressive arthropod of its kind.

The Brazilian has two species: jumping and running, but they are all equally poisonous. What does he look like?

Spider appearance

An individual of this species of spiders is very large, sometimes its dimensions reach a length of 10 cm. The size of the head and chest are small, in contrast to its belly, which is very thick, since the spider feeds a lot.

The legs are very massive, covered with hair, which makes it look the most menacing. The color changes depending on the habitat. Sometimes it can be dark brown, sometimes with the addition of green speckles or brown with reddish hues.

Another feature by which you can easily determine that this particular spider is in front of you is a method of protection that also determines its appearance. During a threat from the environment, he takes a very interesting position, stands on his hind legs, and raises his front legs up. During such a ritual, he sways from side to side, his chelicerae (jaw apparatus) become crimson red.

Reproduction and life cycle

It is often found in nature that female insects are larger than the male, and this is the case with spiders. After mating, the female can eat the male, but some species live in families in the same nest, and since the Brazilian is constantly wandering, it sometimes happens that the male spider is a victim.

In adult representatives, the mating dance looks very interesting. The male offers the food he has caught to the female, who cannot resist and freezes. At this time, mating takes place.

After a few weeks, the female lays her eggs in a cocoon and guards it until the appearance of young nymphs, which then independently disperse through the tropics and roam in search of food in order to grow to large sizes.

Diet

During constant movement, the spider is looking for prey, which can be insects, small spiders, and even attacks tropical frogs, birds and lizards.

The arthropod got its name "banana" for a special passion for fruits. Because of this, the spider can often be found in boxes of bananas prepared for export. Thus, it can be imported to another country.

But the basis of the diet is still meat food. Once inside, the poison turns the insides into a broth, which is subsequently sucked out by the insect.

Lifestyle

The soldier spider, as it is called for the way it raises its front legs up, is a nocturnal resident, that is, during the daytime it hides in a cool place. Such a place can be a snag or a stone (on the ground). Seeing the prey, the spider instantly makes itself felt. The insect wanders at night.

During an attack on small animals, he plunges his jaws and injects poison into the body, which paralyzes the animal in a couple of seconds. If the insect managed to get into the house, then it immediately hides.

Its storage can be shoes, clothes, hats. And therefore, people can suffer due to their illiteracy, that is, not checking the items of clothing before putting them on.

Habitat

Its habitat is the tropics and subtropics of South America. They prefer an earthly location, but often climb tree trunks, hide in dense wet foliage.

In Russia, such a representative of wildlife has not been recorded, but still you should not be careful. He has a replacement that is not inferior in danger - this is a black widow.

Human danger

The poison of the Brazilian representative of arthropods for humans carries a mortal danger.

It contains a neurotoxin that, when released into the human bloodstream, causes the following symptoms:

dizziness;
increased blood pressure;
increased body temperature and fever;
asthma attacks followed by respiratory arrest;
stiffness of the limbs;
complete atrophy of muscle mass.

Poison is most dangerous for males, the reasons for this are unclear. They have a painful erection that lasts for a long time.

If you managed to meet with a banana spider, then after biting once, he does not try to escape, but strives to do it again. Once in the child's blood, the neurotoxin causes a severe allergic reaction, in which in some cases the child cannot be saved without even being taken to the nearest ambulance station.

And since the South American countries are not very rich in experienced medical workers, and some settlements do not see them at all, an antidote that is not introduced in time takes a person's life.

Important! Independently, the insect does not attack the victim. This is what happens in self-defense. For example, if you put on a shoe that has a spider in it and thereby crushed it, then it is not surprising that it will bite you. Therefore, caution is needed here.

An interesting fact of a wandering American that describes the symptoms of a spider bite. The incident happened in 1998. While sorting bananas into boxes, he was accidentally bitten by a soldier spider. It looked like this: as if a long sharp dagger was stuck in the hand.

The hand immediately swelled up, the head swirled sharply. His heartbeat increased to such an extent that it seemed to him that it would break out. Breath intercepted, there were spasms. The doctors were in the right place and on time, they injected him with an antidote, which made the American stand up on his feet the very next day.

Time from bite to death

This concept is very vague, since it is impossible to define this period of time with the same name, it all depends on the resistance of the human body and the immune system.

Video: Spider Danger

If you believe the stories of travelers, then this time can be 30 minutes if the bite fell on a small child. And a little longer if an adult was bitten. Not every time there is a doctor with an antidote nearby, so a meeting with a spider can end tragically.

lethal dose of poison

It is believed that one bite and the injected portion of the poisonous substance is enough for death to occur. During a bite, a person may not feel the introduction of poison, but after a second the skin begins to burn, the poison enters the lymph and blood. In 80% of cases, you are guaranteed cardiac arrest.

If you determine the amount of poison that is needed to kill your victim, then it is as follows: for little rodent enough 6 mcg directly into the blood and a little more, about 130 mcg under the skin. You can calculate the dose for humans, given that the average weight of a rodent is about 50 grams.

Antidote

Today, medical scientists have nevertheless developed an antidote against the action of the poison of the Brazilian wandering insect.

Getting it is a very difficult process, but still it helps many. Due to the presence of antivenom, mortality from bites is reduced. According to statistics, it is 3%.

Conclusion

Summing up the whole story, we note that the spider causes danger if he himself senses danger from environment, he himself will not attack first. This must be remembered whenever you encounter arthropods, be it a Brazilian or other poisonous spider.

But there are real extremals for breeding exotics. And the Brazilian spider is their favorite pet, kept in glass terrariums.

Yandex.Taxi will launch a cargo transportation service
The new service will provide an opportunity to order cargo transportation at two rates. It will also be possible to use the service of a loader. The first tariff allows you to order a passenger car (Citroen Berlingo and Lada Largus) with a cargo compartment with a total carrying capacity of not more than 1 ton. The second tariff includes small-tonnage vans with a carrying capacity of up to 3.5 tons, for example, Citroen Jumper and GAZelle NEXT. The cars will be no older than 2008, Kommersant reports.
Also, customers will be able to order transport with loaders, but if the driver works alone, he will not receive such orders. Yandex.Taxi promises "special bonuses for some partners and drivers" who subscribe to the new tariff.

The most poisonous spider in the world, according to the Guinness Book of Records, is considered " brazilian wandering pau To". This spider got its name because it does not sit in one place and does not weave cobwebs, but actively moves in search of food. Others extremely dangerous spider counts Black Widow- which can be found in the Caucasus and in the Crimea.

Brazilian wandering spider ( Phoneutria) - fast, very active and most importantly - poisonous. Brazilian name of the animal: aranha armadeira, aranha de bananeira (aranha armadeira, aranha de bananeira) - armed spider or banana spider.

This spider deservedly received its telling name: it does not weave webs, like most spiders, because it does not need it. The wandering spider never lives in one place, but always roams. It is unpleasant for a person that sometimes he enters houses. In South America, these spiders are often found in clothes or in boxes with things and food.

A wandering spider is found only in America, and even then most often in tropical and subtropical regions. There are two types of Brazilian wandering spiders - these are jumping spiders, which pursue their prey with jerky jumps, and running spiders. The latter run very fast, but lead a nocturnal lifestyle, and during the day they sit under stones or hide in some other place, including in people's houses.

The Brazilian wandering spider loves to feast on bananas, and will not miss the opportunity to climb into a box with this fruit. For his predilection, this spider received another name - a banana spider. But the main food for him is still not fruits. It hunts mainly on other spiders and insects, and it also happens that it attacks birds and lizards that are larger than it.

He himself is a rather small predator - only some 10 cm. But his small size does not prevent him from being an excellent hunter and a serious problem for people, and all from the fact that he is able to release a solid dose of toxic poison when biting, which is formed at the ends of the chelicera, in the channels of the poisonous glands.

Maybe poison wandering spider less dangerous than snake venom. He is unlikely to be able to kill an adult healthy person - he will only cause a serious allergic reaction, which modern medicine is able to quickly cope with. But if a Brazilian wandering spider bites a sick person or a small child, then the poison can work faster than an ambulance arrives. Some specimens of this spider are so dangerous that the death of a person can occur within 20-30 minutes if immediate help is not provided.

Fortunately for the people of Russia, wandering spiders they do not live here and are unlikely to ever appear: the climate is not quite suitable. But you still need to remember to be careful when handling these arthropods, in case you still have to meet them.

By itself, a wandering spider does not attack a person. It bites only in self-defense. But the problem is that these spiders love to hide and are very hard to spot. If you find a wandering spider, try to get it out of the house as soon as possible and look through all the boxes and cabinets to see if there is another one in them. If possible, you must be as careful as possible and in no case take the spider in your hands.

Karaku?rt(from the Turkic "kara" - black and "kurt" - a worm, an insect; lat. Latrodectus tredecimguttatus) or a steppe spider - a species of poisonous spiders from the genus of black widows.

Karakurt- spider of medium size (female 10-20 mm, male 4-7 mm), black with red dots on the abdomen. Distributed in the desert and steppe zone of Central Asia, in the Caucasus, in the Crimea, as well as in Iran, Afghanistan and along the coasts mediterranean sea. Favorite places habitats - virgin sagebrush, wastelands, banks of ditches, slopes of ravines, etc.

For humans and farm animals, only female spiders are dangerous. The bites of the female can be fatal to humans and animals such as camels and horses. The male, having a much smaller size, does not pose a danger to humans, since it cannot bite through the rather thick human skin. It does not pose a danger to animals to the same extent as the female. Mature females are the most poisonous. Karakurt poison not only 15 times stronger than poison one of the scariest snakes rattlesnake, but in general is one of the most toxic substances of organic origin on Earth.

The frequency of bites in some years increases sharply due to the mass reproduction of karakurt. The number of victims increases during periods of migration of female spiders - in the summer months.

Poison karakurt neurotoxic, causes an exceptionally intense release of acetylcholine in the neuromuscular synapses, as well as acetylcholine, norepinephrine, dopamine and alpha-aminobutyrate in the synapses of the central nervous system, as well as intense in the sympathetic-adrenal system.

The most common cause of a bite is the crushing of a spider that accidentally crawled into the clothes or bed of the victim. In most cases, people who are sleeping or resting in shady places are bitten. Defeats prevail in rural areas and in the field. In cities, karakurt bites are extremely rare.

Karakurt often attacks a person unexpectedly. Especially active in summer at night. The bite is not painful and is often not felt by the victim. There is no local reaction to the poison or it is very weakly expressed - around the bite site there may be a zone of skin blanching (several centimeters in diameter), surrounded by a rim of mild hyperemia. In most cases, there are no local changes and it is extremely difficult to find the bite site. Sometimes a bite is perceived as a needle prick. Due to the low pain of the bite (unlike stings by scorpions, wasps), many victims, especially those bitten at night during sleep, do not associate their sudden illness with a bite of a poisonous insect, seek medical help due to the general manifestation of intoxication.

General toxic phenomena develop rapidly, 5-30 minutes after the bite, and rapidly progress. The severity of poisoning varies from relatively mild, quickly transient forms to extremely severe, sometimes fatal cases. For pronounced forms, excruciating muscle pains are characteristic, combined with paresthesias in the limbs, lower back, abdomen and chest. Patients are excited, often covered with cold sweat, fear of death is expressed, the face is tense, hyperemic, sclera " poured"blood, facial expressions are poor, the facial expression is suffering. Often there is lacrimation. Soon after the bite, a sharp muscle weakness develops, especially of the lower extremities, as a result of which patients have difficulty moving or cannot stand at all. Excruciating pain syndrome (breaking, pulling and tearing pains of different localization) are combined with pronounced muscle tension.

The abdominal muscles are often very tense, which, together with dryness of the tongue, intestinal paresis (peristalsis is weakened, gases do not escape), severe leukocytosis and an increase in body temperature to 38 ° C and above, mimic the picture of an acute abdomen (there may be cases of erroneous surgical intervention with bites of karakurt). Nausea and vomiting may also occur. However, the correct diagnosis is easy to make when considering other symptoms. Tension and dysfunction of the muscles of the extremities, back, occipital (head thrown back, positive Kernig's syndrome), their tremor and convulsive twitches, dysfunction of the respiratory muscles (saccadic breathing), spasm of sphincters - narrow pupils, urinary retention with an overdistended bladder, increased blood pressure (toxogenic karakurt hypertension) - create a very characteristic picture of the disease and allow you to make the correct diagnosis.

In extremely severe cases excitation replaced by apathy, depression, confusion (sometimes with psychotic reactions), collapse and progressive shortness of breath with symptoms of pulmonary edema (crepitus and moist rales, foamy sputum).

Some sick a rosaceous rash appears on the skin. The acute phase of intoxication is especially characterized by the phenomenon of layering pains of different nature and localization on top of each other, combined with a feeling of fear, excitation, sharp muscle weakness and tension of various muscle groups, disturbances in peristalsis and urination, increased blood pressure and body temperature. In mild forms of poisoning, painful phenomena stop by the end of the first day, in moderate and severe forms, they can last 3-4 days.

Right after the bite but no later than two minutes later) you can cauterize the bitten place with a flammable match - from heating, the poison that has not had time to be absorbed is destroyed. This method is indispensable away from medical care. In other cases, urgent hospitalization is required. Otherwise, the bite can lead to the most disastrous results.

Walking through the favelas (the so-called slums) of Rio de Janeiro at night is suicide! There are creatures with whom you will be very uncomfortable. Look at this creature - in front of you is an ominous Brazilian traveler spider and jokes are bad with him.

These spiders are very aggressive. In danger, spiders raise their paws, exposing their fangs - this warning should be taken seriously. It is known to be one of the most venomous spiders in the world. Its bite can be deadly, but its venom also has a strange effect on the human genital area.

If you are a man and if you are bitten by such a spider, you will suffer a very painful and lasting erection. Scientists are still debating what effect it has on women, but the male brain takes chemical substances in the venom of this spider for the substances that the brain produces, causing an erection.

Please note that this spider has been able to cause such an effect for millions of years, and people have only recently developed drugs that cause a similar reaction.

This spider has successfully changed its habitat from the jungle to the city and doesn't seem to be leaving Rio anytime soon.

Reference:

The Brazilian wandering spider (Phoneutria, banana spider, Brazilian traveler spider) made it into the 2007 Guinness Book of World Records for being guilty of largest number human deaths caused by spider bites. Importantly, these spiders are dangerous not only for their poison, but also for their behavior: they do not sit still and do not weave a web, they wander the earth, hide in buildings, clothes, boots, cars, anywhere; which significantly increases the risk of unexpectedly meeting them and being bitten.
