Top 10 most dangerous spiders in the world


Tenth place in the wolf spider. If you do not tease him, the person does not touch. In the case of a bite, a burning sensation and a slight pain may appear, but it does not pose a danger to a person.

The family of wolf spiders is divided into more than a hundred genera and has almost 2.5 thousand species. They live all over the world, except Antarctica, although they prefer a warm climate.

These spiders do not weave, but attack the victim from an ambush. For this and the habit of hunting alone, they got their name. Their sizes are 10-35 mm. It is interesting that females independently bear offspring - they carry a cocoon with spiders with them.

9. Brown Widow

The brown widow is a shy creature and tries to avoid conflicts, but if provoked, the bite is almost guaranteed. The poison is very strong, but it injects only part of it, and therefore does not pose a great danger to the bite. Usually a person feels mild pain, and toxins are eliminated from the body within 24 hours.

This species is a “relative” of the black widow known to all, you can recognize it by the yellow or orange pattern on the abdomen in the form of an hourglass and by the black stripes on the legs.

Distributed in South America and the southern United States, in Asia, Australia and southern Africa. Females are much larger than males and much more dangerous.

8. Sydney leukopautin (funnel) spider

One of the few arthropods that can kill a person - its poison is very dangerous. As a result of the bite, blood pressure rises, profuse salivation and tears flow, muscle twitching, shortness of breath occurs, and without urgent medical help you can die from suffocation within half an hour.

Since 1981, when the antidote was invented, not a single person died, but before that in the last century there were 13 deaths.

Surprisingly, the poison selectively acts only on the insects that the spider eats, primates and humans, but does not pose any danger to other animals. Sydney leukopautin spider lives exclusively in the eastern part of Australia. It is also called funnel because it weaves a web of unusual conical shape.

7. Brown Hermit Spider

The degree of danger of the poison of this spider depends on the size of the injected portion. The bite is almost insensitive, like a needle prick. But soon a wound appears in its place, which is covered with a black scab and can heal up to three years. Several deaths are known, mainly among children and the elderly. A brown hermit spider is common in the eastern and southern United States and northern Mexico.

It is not aggressive and bites only in cases if, through carelessness, it is disturbed.

But this probability is quite high due to the habit of this spider to settle in secluded corners of houses, it can even be found in bed. Outwardly, it is easy to confuse it with a harmless haying spider, so usually people do not see danger in it.

6. Northern leukopautin spider

The poison of this spider is even more powerful and deadly than that of the Sydney leukoputin spider - its relative.

Cases of human bites are extremely rare due to the fact that their habitats are away from human habitation - in the forests of eastern Australia, on trees.

Usually hides from the sun in nooks and is active at night. It grows to eight centimeters.

5. Red-backed Spider (Australian Widow)

Allocates a deadly neuroparalytic poison. As a result of a bite, you can die from suffocation. Thanks to this, the poison is considered the most dangerous in Australia. It is found everywhere on this continent, including in cities.

He likes to hide in dry, warm places, so you can stumble on him, for example, in a street toilet or putting on old clothes in which he lurks.

This spider can be recognized by the red stripe on the back. The bite is very painful, severe pain spreads throughout the body. Since the invention of the antidote in the 50s of the last century, no deaths have been recorded.

4. Six-eyed sand spider

The six-eyed sand spider has a unique, not yet sufficiently studied poison that destroys the walls of blood vessels, resulting in a slow death from blood loss.

Two fatal cases have been recorded.

These spiders live in South American and African deserts. They burrow into the sand and from there attack the victim. Fortunately, people are extremely rare.

1. Steppe black widow - karakurt

All black widow spiders cannot boast huge sizes, but they produce incredibly strong neurotoxins, which are much stronger than the venom of a king cobra. A karakurt bite is felt immediately due to a sharp pain, and after 30 minutes it spreads throughout the body. For several days a person feels dizzy, weak, vomiting, and in more severe cases, deep depression may occur with loss of clarity of consciousness. If the victim is not provided with timely assistance, then after about 5 days he may die. In steppe karakurt only larger females are dangerous, males themselves become their victims. Karakurt is the only truly dangerous spider for humans, whose habitat partially covers the territory of Ukraine and Russia (Black Sea, Priazovye), it is also in the steppes of Kyrgyzstan and Kazakhstan.

2. Sydney funnel spider

This spider is not only poisonous, but also very aggressive, it is ready to attack any person within its reach. He uses protein deltaatracotoxin, which is deadly for primates, and therefore for humans, causing respiratory paralysis and nervous system paralysis. The Sydney funnel spider lives near Sydney, but its habitat is gradually expanding. Males of this large spider are smaller than females, but more toxic and mobile, it is they who, traveling, penetrate into human homes. An antidote has been made against its toxin for a long time, and if it is administered on time, the person will remain alive.

3. Chilean hermit spider

It is considered the most dangerous among hermit spiders. As a result of the action of its poison, skin and subcutaneous tissue cells die.

The bite causes severe pain and burning, as with a burn, and leads to death in ten cases out of a hundred.

The rest of those bitten have to treat necrosis for many months. These spiders themselves do not attack a person and usually bite when accidentally hit under clothes. Distributed in South America. There are sizes up to 4 cm.

3. Australian Widow (redback spider)

This is one of the most famous Australian spiders and the most poisonous on the Green Continent. It can be confidently distinguished by a black round abdomen with a bright red longitudinal mark, such a spider can not be confused with others. Worst of all, red-backed spiders love to settle in urban environments, which provides people with fairly frequent meetings with them. They hide in old sheds, in woodpiles of wood, in dry places under awnings. When bitten, they can control the dose of the injected poison. In severe cases, the pain from a bite becomes prolonged, swelling spreads from the bite area, sweating, nausea, and abdominal colic appear. Bitten children and old people can even die from the bite of an Australian black widow without assistance.

2. Black Widow (Karakurt)

Probably the most famous poisonous spider in the world. Its poison is quite dangerous. However, in art and the media, an ill-founded legend was created, thanks to which many are convinced that the bite of a black widow leads to inevitable death.

There are 13 known deaths among children and the elderly in the United States in the twentieth century, yet most people get off with unpleasant sensations and pain at the site of the bite.

The habitat of the black widow is the United States, southern Canada and northern Mexico. A distinctive feature of the view is a red pattern on a black glossy abdomen. Males of this species are much smaller than females and quite harmless. Black widow females eat males after mating, which is why they got their name.

1. Brazilian wandering (wandering) spider

In 2010, the Brazilian spider was listed in the Guinness Book of Records as the most dangerous on the planet. Its poison has a neuro-toxic effect on the body, the bite is incredibly painful and leads to failure of the muscles, lungs and heart, death occurs from suffocation.

This is one of the largest spiders - up to 15 cm. It lives in the South American tropics and is also called banana for its habit of hiding in banana leaves.

During the day, hides in crevices and other inconspicuous places, and at night “wanders” in search of prey. Having sensed danger, he becomes in a rack and begins to attack, while never retreating. He likes to climb into houses, bags, clothes, and often people become victims of his bites by negligence.

4. North American Black Widow

The name of this web spider already speaks for itself. Although in fact, only 13 people have died from the bite of a black widow in the last century. But before a vaccine against his poison was developed in 1908, 5% of those bitten died. The poison of this type of arthropod spreads through the lymphatic system, activates red blood cells and provokes an allergic reaction. Such spiders are found not only in North America, but also in Australia and even New Zealand.

5. Brown Hermit Spider

Residents of the southern United States and northern Mexico when meeting with a violin spider (brown hermit spider) have to be careful. Its toxin has a necrotic effect on the victim’s tissue. Depending on the dose of injected poison, a slight inflammation, deep tissue necrosis may appear, and sometimes even be fatal.

5th place. Karakurt

The second in our rating variety of spider-web-spiders and a direct relative of the black widow is karakurt. The back is covered with bright red spots. Having reached the age of puberty, some individuals change color to completely black.

Karakurt prefers to live in warm regions of the planet, such as Asia, North Africa, the South of Russia and Ukraine. The bite of a female karakurt is sometimes 15 times more poisonous than that of a rattlesnake. The spider itself does not attack, preferring to counterattack. The victims of a karakurt bite with a fatal outcome are mainly rural workers and livestock.

6. Brazilian wandering spider

These representatives of arthropods are not only poisonous, but also very jumping and fast. They easily penetrate into pockets, bags, cars and houses, where they begin to pose a serious danger to the inhabitants of Central and South America. Almost always, their poison does not lead to human death (only 0.3% die), but even muscle paralysis, followed by suffocation, seems to be a minor problem. Worst of all, men who, after being bitten by a Brazilian wandering spider, risk becoming impotent.

4th place. Black Widow

A spider with American roots and extremely dangerous to humans - a black widow. Males have a burning black color. Females of the black widow are distinguished by a red spot on the abdomen, resembling an hourglass. There are more females in nature. This is due to the fact that after mating, the male becomes the victim of his chosen one.

In relation to other inhabitants of the fauna, the black widow is not aggressive. Arachnid prefers to defend his interests rather than attack. After a bite of a predator, a person begins cramps, nausea and shortness of breath. A black widow bite is especially dangerous for children and the elderly. Their organisms are unable to cope with the action of the poison, and a fatal outcome can occur.

Cross spider

There are about 600 species of spiders with a cross on the back. They inhabit almost everywhere, preferring places with a humid tropical climate. They can be found in forests, parks, near water bodies, often they settle in abandoned buildings. The size of the spider does not exceed 4 cm, the color varies from yellow-brown to dark gray, depending on the habitat. The crusader feeds on small insects. For a person, it does not pose a serious danger, but it can bite through the skin and inject a small amount of poison. People who are most susceptible to poison may experience severe headaches, weakness, itching at the site of the bite, and other unpleasant symptoms. The pain from a bite is tolerant in itself and passes quite quickly.

7. Six-eyed sand spider

These archaic arthropods live in the South African deserts and in the west of South America, and for so long that there are times when these continents were a single continent. These spiders do not know the web, but expertly burrow into the sand, where they await their victims. Scientists investigated the strength of the poison Sicarus hahni, letting them bite rabbits, which died 5 hours later. The toxin of this spider destroys the walls of blood vessels and red blood cells. Throughout history, there have been only two proven cases of a human bite with a six-eyed sand spider, but both ended tragically for victims who died from internal hemorrhage.

3rd place. Sydney spider

Aussie belongs to the genus of araneomorphic funnel spiders, of which there are 516 species, out of 42 families. The main habitat of the Sydney spider is Australia, not far from Sydney. In the rest of the world, this representative of the funnel dynasty can be found in collections and terrariums. Outside, arachnids of this species prefer to live in moist places, basements of residential buildings or in caves.

The average length of the reticulated network reaches 60 cm. The shape of the web is in the form of a funnel. Therefore, the spider family was called funnel. The male grows up to 2 cm, and the female up to 3.5 cm. The individuals are very aggressive. The male secretes poison 5 times more toxic than that of a female. After a bite, a person may die. And bitten pets can easily tolerate the effects of a bite. It is not known why, but the poison is especially dangerous for primates (humans and monkeys).

Mouse spider

This representative of arachnids, growing up to 3 cm, lives in Australia. Males have an unusual appearance: a black, sometimes bluish body, a bright red head and the same chelicera. Females are usually monochromatic - black. The spider feeds on small insects, luring them into deftly woven networks. In a person, his bite causes severe pain, the place where he stuck his jaw can swell. But the spider “saves” its poison, so in most cases, people are not in danger. Lethal outcomes from a meeting with a mouse spider are not fixed.

2nd place. Sand six-eyed spider

Arachnid, inferior to first place in the ranking of “the most terrible spiders in the world”, is a six-eyed sand spider. The concentration of poison is so great that to survive after a bite is quite difficult for both humans and any large animal. A careful study of the six-eyed spiders began in the middle of the XIX century. He headed the works of biographer and scientist Baron Charles Walker.

For their habitation sand six-eyed spiders have chosen regions of South Africa and South America. These arthropods prefer sandy soils, dunes, stones and driftwood. Hunting tactics are expectant, while six-eyed arachnids burrow into the sand.

Karakurt - the most dangerous spider in the world

Karakurt, or as it is also called a black widow, cannot boast of its impressive size, but it is capable of producing such a powerful poison in which the content of neurotoxins is many times higher than the cobra venom. After a bite of a dangerous karakurt spider, a person feels a sharp pain, which spreads throughout the body in half an hour. The next five days of a bitten person pass, as if in a fog, with weakness, dizziness and vomiting. If the victim is not provided with appropriate assistance, then he dies. The danger to life of Homo sapiens is represented only by females of karakurt, since males very often become victims themselves.The habitats of the most dangerous spider are the steppes of Ukraine, Russia, Kyrgyzstan and Kazakhstan.

1st place. Brazilian wandering spider

The first place among the most poisonous spiders in the world belongs to the Brazilian wandering, wandering or banana spider. The most dangerous arachnids chose the tropical forests of South America as their habitat. The average body size of an individual is 13-15 mm. The main hunting time is night. At this time of day, the spider moves in search of the victim, and does not sit in ambush. Therefore, the arthropod creature was called wandering or wandering.

After a bite, a person paralyzes muscle tissue, making breathing difficult. However, only 30% of the poison is sacrificed, giving an impressive chance of survival.

Sydney funnel spider - one of the 10 most dangerous spiders

Sydney funnel spider is very aggressive and always attacks the person first. His bite causes paralysis of the human nervous and respiratory systems. Males are poisonous to females and more confident, and therefore fearlessly penetrate into human homes. The victim needs to introduce an antidote as soon as possible, it is good that this type of dangerous spider lives in Sydney, where the antidote was invented long ago.

Australian widow - one of the most dangerous poisonous spiders

Every resident of Australia knows this dangerous spider. The Australian widow is different in appearance from other spiders. He has a round red mark on his round belly. The spider settles in an urban environment, and therefore his meetings with humans are not uncommon. During the bite, an Australian widow controls the dosage of the poison, but small children and elderly people die without the need for medical attention. After a bite of an Australian widow, swelling, colic, excessive sweating and unpleasant nausea persist for a long time.

Want to know everything

The most poisonous spider in the world, according to the Guinness Book of Records, is considered the "Brazilian wandering spider." 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. Another extremely dangerous spider is considered the Black Widow - which can be found in the Caucasus and Crimea.

Brazilian Wandering Spider (Phoneutria) - fast, very active and most importantly - poisonous. Brazilian animal name: aranha armadeira, aranha de bananeira (aranya armadeira, aranya de bananeira) - an armed spider or a banana spider.

Photo 2.

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

A stray spider is found only in America, and even then most often in tropical and subtropical regions. Two types of Brazilian strolling spiders are jumping spiders, which pursue their prey in abrupt 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, will not miss the opportunity to get into the box with this fruit. For its addiction, this spider received another name - a banana spider. But the main food for him is still not fruit. It preys mainly on other spiders and insects, and it also happens that it attacks birds and lizards, which are larger than it.

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

Perhaps the poison of a wandering spider is less dangerous than the poison of snakes. 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 small child, then the poison can act faster than the ambulance arrives. Some instances of this spider are so dangerous that a person’s death 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 entirely suitable. But all the same, one must remember the caution of handling these arthropods, suddenly you still have to meet with them.

Photo 5.

In itself, a wandering spider does not attack a person. Bites only for self-defense. But the whole problem is that these spiders love to hide and they are very difficult to notice. If you find a wandering spider, try to quickly remove it from the house and look at all the boxes and cabinets: if there is one more in them. If possible, you should be as careful as possible and in no case take a spider in your hands.

He is ranked among the most dangerous spiders in the world. However, a group of Brazilian scientists found that the poison of this spider is effective in the treatment of erectile dysfunction. Scientists who discovered these properties of deadly poison carried out experiments on rats, and the test results were published in a journal called Sexual Medicine. The report provided information that injected the PnTx2-6 spider toxin into the experimental animal after twenty minutes caused a long erection 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.

Six-eyed sand spider - a dangerous representative of the arthropod squad

The six-eyed sand spider earned its name due to the fact that it skillfully bury itself in the sand and hunt for prey. Nature did not reward the six-eyed sand spider with the ability to weave a web. This feature distinguishes this representative from other classes of spiders. The bite of this dangerous spider causes hemorrhage, but only two cases of death are known to science. Scientists conducted more than one experiment on rabbits, as a result of which all test subjects died after being bitten by a six-eyed spider.

The most dangerous spider on the planet: mouse spider

The mouse spider is not in vain has such a strange name, because it lives underground in burrows. The dimensions of the dangerous spider are small. Large representatives of the order of arthropods of this species reach only three centimeters. For humans, the poison of a mouse spider is very dangerous, but the mouse spider is very "greedy" and often bites without injecting a dose of the poison.

Tarantula is the biggest dangerous spider

Tarantula is the largest representative of the arachnid class in the world, which lives in the desert or arid steppe. For humans, the tarantula venom is not fatal and causes only edema. Legends about the poisonousness of a tarantula go for centuries. With one bite of the tarantula, the emergence of entire epidemics was associated. Even a dance called "tarantella" arose thanks to the myth that frantic dance saves from a bite of a tarantula.

Today we introduced you to a dozen dangerous spiders that pose a threat to human life. Try to avoid contact with the above dangerous spiders, which nature has awarded the real opportunity to "defeat man" in the literal sense of this expression. Do not risk your life. Be careful and careful!

Golden (yellow) spider

A small spider, which reaches 2.5 cm in length with its paws, is found in Europe, southern Africa, eastern Asia and the Australian continent. His body is usually pale yellow with dark brown chelicera. He prefers to live in shrubs and thickets, but can also be found in rocky terrain. The golden spider is one of the most biting, while its poison, although it does not lead to death, but causes many unpleasant consequences. In particular, in a person after a painful bite, nausea occurs, the temperature rises, blisters appear on the affected area of ​​the body, and then itching.

Who are spiders and their varieties

The few differences between the ancient spiders were that, firstly, they were most likely larger, there is even a theory that prehistoric spiders were larger than 1 m. Secondly, they were more active hunters, that is, they did not they waited until their victim fell into the "network", and quickly attacked it themselves.

The ancient spiders used the web more for housing. Over time, spiders, like all other living creatures, developed, became smarter and more cunning: they learned to build spider webs, and the need for active hunting disappeared.

Various species of spiders live almost everywhere, even in Antarctica. Spiders eat quite a lot and the main condition for the life of a spider in any locality is insects, or rather the ability to find them and, of course, eat them. Most of the spiders live on land, but nevertheless there are species that prefer water.

Most of the spiders are included in one of two main suborders: orthognath and labidognath. Spiders of the first detachment are usually quite large spiders, densely covered with hairs. They love the warm climate and, as a rule, live in holes that they themselves dig out. An orthognate suborder includes, for example, a tarantula spider. Detachment labidognata more numerous, it includes most species of spiders.

They differ from the first detachment by the presence of tracheas for breathing, a more powerful jaw and size: they are smaller.

Most spiders pose absolutely no threat to humans, moreover, they are even useful to humans. Spiders eat many harmful insects, such as aphids, bedbugs, leafworms, which often literally save fields and vineyards. Spiders never attack humans unless, of course, they are provoked.

Even if a spider bites a person, he, as a rule, will not be able to do him much harm, because spider venom is most often not stronger than that of a wasp. The most poisonous spiders in the world, however, if provoked to attack, they can greatly harm human health, even death.

Whatever the most poisonous spiders in the world, they have the same structure. It's all about poison.

Therefore, of course, do not disturb the little-known spider, touch it, especially if it is beautiful and bright. Often, the more beautiful and unusual the spider, the more aggressive and toxic it is, and therefore more dangerous.

Top 10 most dangerous spiders on the planet

Most spiders found in ordinary everyday life can only harm insects, turning them into their treats. Spider-man often does not even notice. The one who is afraid of these creatures, feels rather not fear, but disgust.

Nevertheless, fear of spiders also has rational basis. The most poisonous spiders in the world exist not only in films about killer spiders, but also in reality, and their poison can really kill a person.

Banana spider

It is also called the Brazilian wandering spider, runner, spider soldier. This dangerous giant killer lives in the forests of Central and South America. Its growth in length with spread legs can reach up to 17 cm. In appearance, it is not very noticeable, not counting the large size. The most common individuals are dark brown.

Wanderers hunt at night, their prey becomes insects and smaller relatives, less often frogs, rodents and chicks. These spiders do not attack humans for no reason, but can bite for self-defense. When meeting with him, you should not try to scare him, because he is not from a timid dozen, and he himself will begin to attack the alleged enemy. The poison of a banana spider acts rapidly, it can lead to the rapid death of a child or a sick person if they are not given an antidote on time. The poison of this particular arachnid is listed in the Guinness Book of Records as one of the most dangerous on the planet.

Terafosa Blond

Terafosa Blond, or Goliath Tarantula, is the largest representative of the spider family in the world. The dimensions of his body can reach 9 cm, and together with his paws - 28 cm. This spider is quite dexterous and strong, it can cope with a toad, a small bird, a rodent, even a snake. The average size of representatives of this species is about 25 cm, the color is light or dark brown, and the legs are reddish.

For housing, Terafosa chooses wet marshy or semi-boggy areas, lives in a rather deep hole, the entrance to which is shrouded in cobwebs.

Despite its impressive size, Blond's Theraphosis is not a dangerous creature at all, although for a long time he was considered such, probably because of its size. Spider venom has a paralytic effect on the victim, but for humans it is harmless and is comparable in strength to a wasp sting.

Terafosa also has another remedy - annoying sharp hairs, which he combes from his hind legs, sensing danger. These hairs bite into the skin and cause severe irritation especially to the mucous membranes of the mouth and nose.

Yellow spider sak

The yellow spider lives in America, Australia, Asia, Africa, it can also be found in southern Siberia and the Volga region. The yellow spider prefers to live in secluded places, for example, in shallow crevices, under piles of stones, in dense grass. Spider Sak has a small size: the size of its body does not reach 1 cm. However, due to the bright color it is easy to notice.

As the name implies, the spider has a bright yellow body color, against which an orange head stands out as a bright spot. The mouth and fangs of a spider, in comparison with the size of its body, can be called huge. In addition, he is very fast and able to jump.

The poison of the Yellow Spider is not as strong and terrible as, for example, the black widow, its danger lies in the fact that it is toxic and can lead to serious consequences in the future, which are difficult to predict in advance. Symptoms after exposure to Saka's poison are similar to symptoms that occur after a bite of a hermit spider, this often confuses doctors.

Intoxication is accompanied by swelling, fever, severe headache and muscle pain, and nausea. Exposure to the poison can even cause tissue necrosis. To help the victim, the wound after the bite should be treated with potassium permanganate, apply a cold compress to it and take the victim to a doctor.

Spiders, no matter how terrible creatures they may seem, even the most poisonous in the world, never look for a meeting with a person. When meeting with these tiny, but very dangerous creatures, it is always worth remembering that until a person touches them, they will not attack.

It’s better to watch these amazing creatures and their lives from afar, and they are really amazing: after all, these ancient creatures still remain largely a mystery.

8. Chilean hermit spider

As the name of the species is clear, this spider hails from South America, but in the process of his wanderings he has already reached some US states - Nebraska, Iowa, Texas and Indiana. Among other hermits, he is one of the largest. The Spaniards at one time called him the "brown spider." The bite of the Chilean hermit spider is very painful and threatens with grave consequences, up to the death. Its poison paralyzes the nervous system and internal organs, causes hemolytic anemia, leading to acute renal failure.

9. Spider mouse

This predator lives in Australia and Chile. They called it so by mistake, believing that this spider, like a mouse, lives in burrows dug underground. The mouse spider is not too big - 1-3 cm. It hunts for insects or other spiders. But he is prey for wasps, scorpions, bandicuts and leg-millipedes. In a mouse spider, a toxin is very dangerous for humans of a protein nature. But, fortunately, he lives away from human habitation. In addition, like a cobra, it saves poison and prefers to bite “dry” out of hunting.

10. Tarantula

Tarantulas are the genus of poisonous large spiders belonging to the family of wolf spiders. They live in arid steppes and deserts, hiding during the day in deep vertical minks. For a number of animals, tarantula venom is fatal, but not for humans. In the south of Russia and Ukraine there is a misgir - a South Russian tarantula, the bite of which can be compared with a hornet bite by pain, it only causes edema.
The most famous representative of the tarantula genus is the large Apulian tarantula, which is found in Italy near the city of Taranto (hence the name of the spider). In the Middle Ages, this spider was considered deadly poisonous and terribly afraid. Therefore, legends were passed down from generation to generation about the terrible "monster", he was blamed for the spread of epidemics. Now it is known that the Apulian tarantula is not poisonous. But once, in order to recover from his bite, people frantically danced to exhaustion - and so the tarantella dance arose.

Our ten Heiracantium opens, having chosen South Africa and some parts of Asia for residence. This dangerous spider can be found in Europe.

The spider is small in size, only 5–10 mm in size, has a pale color with a yellow, and sometimes a beige shade of the abdomen.

A spider bite is not fatal, but causes severe pain at the site of the bite, redness and swelling. Sometimes, in order to get rid of painful sensations, it is enough to rinse the bite site with cold water. By the way, about the biggest spiders in the world on our site you can read an interesting article.

Chinese tarantula

The inhabitant of Southeast Asia has a toxic poison that can immobilize and even kill a small mammal. In history, even the death of an infant from the bite of this large tarantula is recorded.

Adult individuals reach quite large sizes with paw lengths of up to 20 cm. To develop an antidote, scientists conducted experiments and found that a small dose of the poison led to the death of most laboratory mice.

Goliath Tarantula

In terms of size, it is the largest spider in the world. Its size and poison allow you to hunt toads, frogs, some types of lizards, and sometimes small snakes become its victims.

The body of a goliath tarantula, as this species is also called, reaches 9 cm. In the middle of the 20th century, a specimen was caught in South America, whose paws reached 28 cm.

The poison is not fatal to humans, but Bitten Goliath (Teraphosa Blondi) bites only in case of extreme danger. He prefers to live in the humid tropics of Brazil, so it is impossible to meet her in our latitudes.


The English call this species of spiders “mouse spiders”, mistakenly believing that they, like mice, can dig holes in the ground.

The size of the Missoulins is from 1 to 3 cm, which is why small spiders feed mainly on insects, catching them in their intricately woven web.

The mouse spider lives in Australia, and with the beauty of appearance, it is considered one of the most poisonous on earth. A bite leads to pain, swelling, and the development of a wound at the site of the bite. Therefore, with a bite, it is better to seek qualified help.

Black Widow

It is difficult to find a person on Earth who has not heard of the most dangerous spider - the Black Widow. The poison causes severe muscle cramps, paralysis, and sometimes death.

Genital cannibalism is common among these spiders. After mating, the female eats its partner. Note that the poison secreted by this spider is several times the deadly poison of a rattlesnake.

A black widow is easily distinguished by characteristic red spots in the form of an hourglass on a black back.

Sydney Atrax

One of the few representatives of the family of migomorphic spiders, which can cause great harm to human health, and sometimes even lead to death.

Adult individuals are relatively small, growing from 2 to 5 cm. They have a characteristic black color with a shiny cephalothorax.

They live in Australia, but subspecies of Atrax robustus have settled around the world: from New Zealand to the shores of the Mediterranean.

Brazilian spider runner

The most poisonous spider on the planet has chosen for life the tropical forests of South America. But often it can be found in the city, where the spider-runner is a frequent guest in the suburbs of Rio de Janeiro.

The most dangerous arthropod grows due to its shaggy legs up to 15 cm. It never weaves a web, but constantly moves, which is why it got such an unusual nickname.

The strongest neurotoxin contained in the poison after entering the bloodstream leads to total muscle paralysis and death strangulation. If you bite, you must urgently seek medical help and introduce an antidote.


So you found out what are the most poisonous spiders in the world. These arthropods by phenotype are determined by zoologists in a separate class. Meeting with them always causes mixed feelings and emotions, and some people have developed a fear of spiders - arachnophobia. This is not surprising, because some representatives carry a real danger for a person, and those who are not dangerous have a terrifying look.

Scientists for many species have developed an antidote, but it’s gonna blow away that many antidotes are also toxic to the human body.

Hundreds of species of spiders live on our planet, and some of them, even poisonous, people even keep as pets. But it’s better to avoid meeting these dangerous representatives of the terrestrial fauna.
