Some people believe that spiders are insects. However, it is not. Spiders are allocated in a separate class, and the structure of their body has some features. For example, insects always have three pairs of limbs. Spiders have one more, that is, four. The differences also apply to the eyes. In insects they are composite, and in spiders they are singular, with lenses. It is possible to distinguish representatives of one class from another by the presence of antennae. Spiders don't have them.
As a rule, arthropods cause disgust and fear in many people. And this despite its relatively small size. However, those spiders that live behind our cabinets and weave cobwebs do not pose any danger to humans. But live on Earth and such representatives of this class, which should be bypassed. These arthropods are terrible for humans. What are they, where can you see them? Consider the top most dangerous spiders in the world. And let's start with the most poisonous representatives.
Brazilian spider
This representative of arthropods is the most dangerous on our planet. For this reason, he was even listed in the Guinness Book of Records. With him, we start the top 10 most dangerous spiders in the world.
Where does he live? Brazilianthe wandering spider can be seen in the American tropics or subtropics. At the same time, two groups of these representatives of the animal world are distinguished. The first of these include jumping spiders. So they are called by the method of persecution of the victim. These spiders catch up with their prey with jerky jumps.
The second group includes running arthropods. These Brazilian spiders are very fast in pursuing their prey. Representatives of the second group go hunting at night. During the daytime, they hide under rocks or in places where they cannot be seen. Such spiders can live both on the ground and on trees.
Why are these arthropods called wanderers? The fact is that the Brazilian spider does not weave a cobweb like its relatives. He constantly changes his place of residence, moving in search of food.
The most dangerous spider on our planet brings a lot of trouble to the inhabitants of South America. This poisonous creature creeps into their homes. The Brazilian wanderer is often found in boxes of food or closets with clothes.
What features does the most dangerous spider on our planet have? It is distinguished by its small size. In length, the Brazilian wanderer can grow up to 10 cm. However, small dimensions do not prevent these arthropods from being the most dangerous spiders in the world (see photo below).
They are excellent hunters, representing a great danger to humans. It is worth saying that the bite of this arthropod leads to suffocation, often ending in death. The good news is that for the salvation of humanlife has an antidote, which should only be administered in time.
Of course, he althy adults do not have to worry about their lives after being bitten by the most dangerous spider on our planet. They can only have a severe allergic reaction to its poison. But toxins that have entered the body of a child or a sick person can lead to the saddest result.
What does the most dangerous spider on our planet prefer to eat? Bananas are his favorite treat. That is why Brazilian wanderers prefer to climb into those boxes in which these fragrant fruits are stored. For such love, this representative of arthropods is often called the "banana spider". However, the main food for him, of course, is not fruits at all. The most dangerous spiders in the world (see photo below) hunt insects.
Even relatives of other species become their victims. In addition, Brazilian wanderers attack birds and lizards that are much larger than them.
The most dangerous spiders in the world do not attack people. They bite a person only for their own protection.
Six-Eyed Sand
Representatives of these arthropods continue the top 10 most dangerous spiders in the world. These are small individuals reaching a length of 8-15 mm. Outwardly, such spiders resemble crabs. Such a resemblance is given to them by comparatively large paws bent at the knees, the length of which reaches 50 mm. Reminiscent of a crab and slightly flattened body shape of an arthropod. This one has its namea dangerous spider (photo below) received due to its inherent shade of brown and the presence of six eyes.
The places of residence of the sandy six-eyed are the territories of South Africa and the lands of South America. Depending on the habitat, these spiders have different concentrations of the deadly substance in their saliva. Thus, African individuals are endowed with a more lightning-fast and deadly poison than their American relatives. Perhaps the reason for this lies in the climatic features of the Namib Desert.
The six-eyed sand spider hunts for small insects. Larger scorpions also become its victims. The spider waits for its prey, burrowing into the sand. In disguise, hairs located on the body help him. Grains of sand stick to them, making the hunter a successful conspirator.
The venom of this spider affects the body of its victim in an unusual and unique way. A toxin still unknown to science negatively affects blood vessels, destroying their walls. This process occurs due to slow necrosis. A detrimental effect is also on the blood of the victim. It begins the active destruction of erythrocytes. Thus, the venom of this arthropod is a very effective murder weapon. Fortunately, encounters between the six-eyed sand spider and humans are very rare. Only two deaths have been recorded as a result of the attack of this arthropod.
Sydney Funnel Spider
This representative of arthropods is small or medium in size. His byThe law was included in the top lines of the list, from which the top of the most dangerous spiders on our planet was compiled. The fact is that his bite can cause death.
Sizes of female Sydney funnel web spiders range from 1.5 to 3 cm. Males are usually a centimeter smaller. The color of the body of these spiders has beige-brown, and sometimes black shades. Two dark longitudinal stripes located on the back help to distinguish these arthropods from their relatives.
The habitat of the described spider is Australia. Most often it can be found in the state of New South Wales. This representative of the animal world loves to settle in forests, as well as in areas developed by people. Funnel-web spiders often roam backyards and can sometimes get into swimming pools. It is undesirable for people to encounter these arthropods, as they become aggressive when threatened.
The Sydney funnel web spider produces a strong poison. Moreover, the toxic substance is produced by arthropods in large quantities. The danger of the spider lies in its long chelicerae. These are peculiar “fangs”, in which, near the very tip, there are channels that remove poison. It is worth saying that the chelicerae of the Sydney spider are larger than those of the brown snake, which is also very dangerous for humans.
The venom of the Australian arthropod includes a component that acts on the victim's nervous system. Getting into the human blood, it changes the functioning of all systems and organs. When bitten by maleseven death is ruled out. In 1981, scientists developed an antidote to eliminate the danger of death to humans. Since then, no deaths have been reported from the bite of the Sydney funnel-web spider.
Black Widow
The top 10 most dangerous spiders in the world continues with this small arthropod. The length of his body is only 1.5-2 centimeters. And although the females of these representatives of arthropods are two times larger than males, they are also quite difficult to distinguish in natural conditions. Nevertheless, these are the most dangerous spiders, which are almost at the top of the corresponding rating.
Black Widow is in constant "mourning". Only sexually mature adults have red hourglass markings on their abdomen. Young spiders are light in color. Their body is sometimes white or yellowish white. Coloring becomes darker only with age. The body of these spiders acquires black color only by the second or third month of life.
This most dangerous spider (see photo below) received its "mourning" name not by chance. The females of this arthropod are distinguished by cannibalism towards males.
The residence of these spiders, as a rule, are the Central Asian deserts and steppes. They are less common in the Caucasus, as well as in the Crimea.
The black widow, ranked third of the 10 most dangerous spiders, prefers to hunt in depressions under stones, placing them at a low height from the groundtheir silks. She also watches over victims in crevices and various holes, over squat plants and even in the thick of grape vines.
Representatives of these spiders go hunting at night. During the day, they prefer to hide in their shelters. Black widows usually feed on insects. However, these spiders are not averse to dine on wood lice and their own relatives.
The bite of a black widow is dangerous to humans. This is especially true for the elderly and children. The poison, spreading throughout the body, causes severe muscle spasms. Also, after the bite of a black widow spider, weakness and headache, shortness of breath and increased salivation, vomiting, anxiety and tachycardia appear. You can neutralize the poison by cauterizing the bite with a match. To eliminate the likelihood of an allergic reaction, it is also advisable to take the victim to the hospital.
Red back
At first glance, a small spider looks like a black widow. The resemblance to this arthropod is given by its black color, a red stripe on the back and a red-orange pattern on the abdomen, similar to an hourglass. However, this spider is not a black widow, since its homeland is Australia. Today, this arthropod can also be found in countries such as Japan, Belgium and New Zealand.
The poison of the red back (a representative of the karakurt family) is more dangerous than the poison of the rattlesnake itself. In this regard, the bite of a small spider can cause serious consequences for humans. After a toxic substance enters the bloodpeople experience pain, muscle spasms, repeated bouts of nausea, and increased sweating. Fortunately, the main food for this spider is small insects, and sometimes even lizards. This dangerous kid does not seek out people, and therefore such meetings occur very rarely.
Chilean hermit spider
This arthropod is also one of the ten most dangerous on our planet. Its habitat is the western territories of the United States. You can meet a recluse spider in the states of Iowa, Nebraska, as well as in Indiana and Texas. This is one of the largest arthropods of this species. The length of his body, taking into account the limbs, often reaches 1.5 inches. Translated from Spanish, the name of this representative of the animal world is "brown spider".
Despite its small size, ranging from 6-20 millimeters, the bite of the Chilean hermit can cause a painful death. Toxic substances contained in his saliva cause paralysis of all internal organs, as well as hemolytic anemia and severe kidney failure.
Spider-mouse
This most dangerous creature is found in Chile and Australia. This representative of arthropods got its name because of the erroneous opinion of people that spiders, like mice, live underground in holes dug by them.
The size of this poisonous representative of the animal world is very small. Its body length is between one and three centimeters.
Victims of mouse spidersare insects. They also eat other spiders. In turn, these arthropods feed on scorpions, wasps, millipedes and bandicoots.
The venom of the mouse spider is of protein origin and is considered very dangerous for humans. Fortunately, its individuals are rarely found near human habitation. In addition, the mouse spider prefers to conserve its venom by making so-called dry bites.
Chinese tarantula
This spider belongs to one of the varieties of the large tarantula. The length of his body is about twenty centimeters. You can meet arthropods of this species in Vietnam and China. Because of their size and ferocious appearance, the locals call these spiders earth tigers.
Chinese tarantula venom has been tested in the laboratory. The results of the experiments proved that the toxic substances emitted by this arthropod, in fifty percent of cases, lead to the death of small mammals.
Ornamental tarantula
These hairy and huge arthropods belong to the wolf spider family. Ornamental tarantulas can be found in the countries of Southeast Asia. Their bite is very painful, and the poison that has entered the human body can cause severe swelling.
Sak
What are the most dangerous spiders in tenth place in the ranking? These arthropods are called golden or golden. We are talking about yellow spiders saks, whose place of residence is mainly Europe. This isa small (up to 1 cm in length) arthropod builds a shelter similar to a bag. Sometimes saki just sit inside their house. The bites of these spiders are clinically dangerous and cause extensive tissue necrosis. However, fortunately, golden saki are not at all aggressive. They can attack people only when there is a sense of danger.
