What are the most dangerous spiders in the world?
Why are spiders dangerous? By the fact that they bite a toxic secret into the body of their victim when they bite. It is worth noting that absolutely all types of these creatures are poisonous, the difference is only in the portion of the poisonous substance and its effect. Thus, it turns out that the bite of one arachnid may well go unnoticed, and the poison of the other will be several times more toxic than snake venom. It is to the latter group that the most dangerous spiders in the world belong. Get to know them better.
What is the danger?
A spider is a predator; therefore, it requires weapons to hunt. And nature endowed him with such - it is poison. However, it is interesting that the poisonous secret of some spiders acts on the victim’s nervous system, while others provoke tissue destruction, which leads to their necrosis.
However, even the most dangerous spiders in the world never attack a person deliberately. They bite people only when they feel the danger, that is, in order to protect themselves, even if they were disturbed by accident. And at the same time, no matter how toxic the poison of a bitten spider is, a fatal outcome is extremely rare, for example:
- in case of untimely provision of medical care;
- when the body is too weak by the disease;
- with allergies to spider bites;
- if the poison got into the body of a child or an elderly person.
On a note! But even in such cases, death does not always occur. Often life can be saved, albeit with serious complications!
Who should be wary of?
Among the most dangerous spiders in the world are far from the largest. And their main qualities are dexterity, speed and, of course, the toxicity of the poison. So who are they?
Brown hermit spider
This is a small nondescript spider, whose body size together with the legs usually does not exceed 2 cm. The poison of this baby causes tissue necrosis, and the damaged area soon becomes like a festering ulcer.
Quite a large amount brown hermit spiders was discovered on the east coast of the United States, where they gladly settled in the homes of local residents. Moreover, these spiders were located not only in corners and other secluded places, they crawled willingly and settled down in cabinets, in shoes and hid simply in clothes. Therefore, in order to get a dose of poison, it was enough to just put your hand in the pocket of your jacket.
On a note! People living in the habitat of this spider have a holy rule - shake all clothes and shoes before putting on themselves!
Some time after the bite, symptoms such as:
- nausea;
- headache;
- general weakness;
- malaise.
The greatest danger is the bite of a brown hermit spider in those cases when the affected area is very close to important organs. In such situations, they are more likely to be affected by necrosis.
Tarantula
For representatives of this genus, desert and semi-desert regions of Eurasia are preferable, but at the same time they can often be found in forest-steppe zones. Tarantulas - these are the biggest spidersoccurring on the territory of Russia. Their body size is about 5 cm.
On a note! Tarantulas are often mistaken for tarantulas, but each of them represents completely different groups. They are similar only to a shaggy little body. Tarantula spiders are huge compared to tarantulas - their paws are about 25 cm wide!
The poison of tarantulas is deadly for insects, and for a person its bite feels similar to a hornet bite - quite unpleasant and even painful, but it usually does not pose a direct threat to life. In this case, the degree of toxicity of the secret will depend on the season and gender of the individual. For example, the most poisonous are females who enter the puberty phase and are waiting for mating. And those tarantulas that have just woken up or will soon go for the winter are practically not poisonous.
Tarantula venom acts on the nervous system and causes symptoms such as:
- local cramps;
- complete numbness of tissues at the site of the bite;
- an attack of severe shortness of breath;
- suppuration of the wound.
Against the background of an allergic reaction, such signs can have a pronounced character.
Six-eyed sand spider
This spider lives in the territories of South Africa and South America and is considered the most poisonous spider in these regions. He can be called the indigenous resident of these places, since he met here before the time of colonization. As for toxicity, six-eyed sand spiders living in Africa are more toxic and dangerous than American ones. But at the same time, the bite of the latter can also lead to death or leave the victim disabled. The action of its poison is compared with the action of sulfuric acid, and therefore the six-eyed sand spider is considered to be one of the most dangerous in the world.
Representatives of this species have a medium-sized body - about 5 cm, painted in light brown or reddish brown. This color allows them to hunt very successfully. Living in the desert, a six-eyed sand spider buries itself in the sand and sits there motionless in anticipation of a victim. Approaching, potential prey creates vibrations with its paws, sensing that the hunter is rapidly attacking. The main food of six-eyed sand spiders are various insects, scorpions and other spiders.
On a note! Six-eyed sand spiders prefer to settle far away from people, and perhaps because of this there are only two registered deaths.
After a bite of a six-eyed sand spider, the cell walls rupture, which leads to tissue necrosis in the affected area.
Sydney spider
He is extremely handsome, graceful and deadly. The Sydney spider is the owner of a massive black body with large paws - its dimensions reach 7 cm. And due to the complete absence of villi, it seems that his body is covered with viscous gloss.
Sydney spider belongs to the funnel family, which includes about 500 species. Some of them live in Russia. The Sydney spider is the most dangerous and poisonous representative of its family and is most common in Sydney (Australia) and its environs.
The representative of this species is very aggressive. He bravely and without unnecessary hesitation pounces on his opponent and inflicts not one, but several deadly bites at once. But at the same time, he always warns of his intentions and before attacking raises the front of the body, throws the first pair of legs apart and shows large chelicera, in the glands of which that poison is hidden.
After a bite of a Sydney spider:
- the affected area is numb;
- limb temporarily paralyzed;
- the victim notes a general deterioration in well-being;
- his condition becomes quite painful.
Procrastination in this case is fraught with a coma, and a small child can die within a quarter of an hour.
Karakurt
He belongs to black widow family and is included in the list of the most dangerous spiders living in Russia.Karakurt originally lived exclusively in the warm regions of Asia, Europe and the African continent. However, due to climate change today it can be found even in the Moscow region, and at the same time karakurt continue to move further north.
On the territory of Russia, two types of karakurt are most often found: a steppe widow and a white karakurt. Representatives of the first species have a black round abdomen with 13 red spots scattered in a chaotic manner.
The body of the white karakurt is also spherical, but completely white. Instead of spots on the upper side of the abdomen, there are four point depressions located in the form of a rectangle.
Karakurt are quite poisonous. The characteristic symptoms of a bite of this spider are:
- slight swelling in the affected area;
- redness of the skin;
- after about an hour, muscle cramps are observed;
- muscle tension of the anterior abdominal wall occurs.
In some cases, others are connected to these symptoms. Possible increased blood pressure, shortness of breath, vomiting and sweating. The victim complains of headaches and general weakness. Often there is urinary incontinence, tachycardia and salivation. In the affected limb “goose bumps” are felt, tingling and its complete numbness gradually occurs.
Brazilian wandering spider
This is the most dangerous spider in the world, a photo of which in the wild can be taken exclusively in the tropics of South America, in particular in Brazil. He is a wonderful hunter and catches his victims without nets. Fully justifying its name, the Brazilian wandering spider does not stay long in one place - its life takes place in constant wanderings, the purpose of which is to find food. Representatives of this species attack the victim with extraordinary swiftness, while they are able to catch and kill not only an insect or other spider, but also a lizard and even a small bird.
If medical care does not catch up on time, then after a bite of a Brazilian wandering spider, a fatal outcome is possible within 30 minutes.
On a note! Often this happens with the inhabitants of the Brazilian hinterland, where an ambulance travels from the city and for this reason does not have time in time!
The Brazilian wandering spider is not afraid to be near a person’s home. Moreover, representatives of this species quite often go into residential buildings, where they hide in clothes. They also love to feast on bananas and often end up in fruit crates. As a result, the packers and pickers of bananas suffer from the bites of these spiders.
No one is safe from the bite of a spider, but you can still protect yourself. To do this, it is enough to revise your clothes, returning from a walk, especially if you are in the habitat of one of the most poisonous arachnids. And when meeting with a dangerous spider, try to bypass it carefully and, of course, under no circumstances try to pick it up.
