And the most poisonous of the arthropod squad is the Karakurt spider (photo and the description may shock you).
Karakurt is also called the black widow. Black – because of this spider-colored abdomen, legs, head.
Widow – because a female almost three times as large dimensions of the male, spouse eats after the marriage ceremony.
But another is more dangerous, this animal is very poisonous.

Habitat
The spider lives in karakurt (photo taken in macro mode, will show the animal on a pebble) mainly in the Crimea, in southern Ukraine, in Kazakhstan, in the southern regions of Russia, Afghanistan, Southern Europe, on Mediterranean, Central Asia and North Africa, in the Astrakhan steppes.
They have migrated recently (probably due to global warming), and they can be found even in the suburbs, Azerbaijan, Altai Territory and in some areas: Rostov, Volgograd, Novosibirsk.
If you are interested in spiders, we recommend that you also familiarize yourself with features of the tarantula spider, which is described in articlehttps: //kot-pes.com/pauk-pticeed-foto-diko-ocharovatelnyj-predstavitel-mira-ekzotiki/
Karakurt nests are equipped in secluded places:
- in mouse minks;
- in crevices;
- in the recesses in the ground;
- in the walls of adobe houses.
They prefer to settle in the steppes and on arable lands, near ditches, ditches, ravines, salt marshes, in wastelands.
They avoid open places, choosing uneven and stony similar to the ferret habitat lemmings.
And here are the hot deserts, wet ravines, shrubs and dense grasses they don’t like it.
Attention! Sometimes karakurt can be found in abandoned buildings and even in your own yard.

Appearance
Outwardly, the spider seems so cute – he has neither a gun nor wool, as, for example, the tarantula.
And the description of the spider of karakurt is very interesting – its body is more looks like a constructor. He has a belly resembling a ball and cephalothorax.
They are interconnected by the seventh segment (as we have vertebra) of the cephalothorax.
Limbs extend from the abdomen: two pairs of jaws and four pairs legs. The abdomen is a symbiosis of telson (anal lobe) and eleven segments.
The female has upper jaws (chelicerae) that end hooks. And on the other side of the jaws are poisonous glands.
Interesting! The bite of a female karakurt at 15 times more poisonous than a rattlesnake bite.
Most correctly, the appearance of the spider describes the Latin name karakurt.
Translated into Russian, it means “thirteen points.” Indeed, on the back of the spider you can see red-orange dots arbitrary shape with a white stroke.
These marks indicate danger, you can determine from them that Karakurt is watching you.
A spider, growing up, does not lose color – the dots remain. A spider transformed, and sometimes instead of spots, she appears on her abdomen yellow stripes.
During the juvenile period, both female and male molt: spider 7 times, and the spider 9 times.
Karakurt females differ from males in both appearance and size. If the males are frail, black and no more than 7 mm in length, then females are just heroes: about 1 cm in length (there are also individuals up to 2 cm in length) with long three-centimeter legs – models would be envious. Yes, and they are rare beauties – the back is decorated red peas

Interesting! Eurasian spider women karakurt in adulthood no longer have spots, and American and Australian always spotty.
Spiders can be called aristocrats, because they have blue blood.
This is due to the fact that they have hemocyanin in the blood, and not hemoglobin, that is, iron is not responsible for the color of the blood, but copper.

Global warming has caused spiders to refuse sleep in the winter.
In autumn, when the first frosts appear, the soil becomes cold, spiders massively perish.
But at the same time they manage to leave offspring.
Spiders grow in cocoons – they feel warm and comfortable there, and crawl out from their houses only in the summer.
Then – in July, August, they can bite and inject poison under the skin.
Interesting! It would seem that they are not afraid of anyone karakurt. But this is not so. Flocks of sheep trample their nests in the steppes and in the clearing, sphyx wasps inject poison into spiders, paralyzing them, riders insects (these are flies with wings – something between mosquitoes, flies and wasps) lay their testicles in cocoons with spiders and hedgehogs – karakurt just won’t reach the hedgehog’s body through barbed fur coat.
Karakurt is a predator, and his digestive system is extraintestinal. Attacking the victim, the spider pierces its upper jaws (chelicerae) and injects poison. And he does several of these injections so that the “food” is cooked faster. Когда все переварится,каракурт высасывает содержимое
Food
Karakurt, like scolopendra, is a predator, and his digestive system is extraintestinal or, as they call it, semi-internal (all predator spiders have such a system).
Attacking the victim, the spider pierces its upper jaws (chelicerae) and injects poison.
And he makes several such injections so that the “food” is faster приготовилась. Когда все переварится, каракурт высасываетcontent.
Karakurt food: cicadas, bugs, grasshoppers, locusts and other invertebrate creatures.
For a year, a spider karakurt can lay up to 1,300 eggs
Breeding
In the mating season, the male actively cares for the female.
But the matrimonial night barely ends when the female eats narrowed – hence the name.
Kalmyks even call these spiders in their own way “belbesen-hara,” which translates as “black widow”.
A female karakurt braids her nest from the inside with a web where fastens cocoons with eggs. For a year, a spider can postpone up to 1,300 eggs.
After a week, spiders hatch from the eggs. But not out crawl out, and live in a cocoon until the beginning of summer.
Karakurt spider can’t bite through human skin, it can make only a spider. Yes, and glands with poison are only found in spiders. Their chelicera are so sharp and durable that they pierce not only skin, but even nails. Females are especially dangerous during the mating season – this is with July to the end of August
Karakurt bites
The bite of a karakurt spider is very dangerous. Although, it’s not really right.
A spider cannot bite through human skin, only it can do the spider Yes, and glands with poison are only found in spiders.
Their chelicera are so sharp and durable that they do not pierce only skin, but even nails.
Females are especially dangerous during the mating season – this is from July to the end august.
Interesting! In the 20s of the last century for the fierce disposition and cruelty in Central Asia called the Basmachi “karakurt”.
The venom of black widows is toxic, neutropic, fatal to humans and even poison resistant animals like mongooses, if you do not help in time.
When bitten by a karakurt, in order to prevent death, the victim needs to enter serum – an antidote in the next 10 minutes
Symptoms
After 10 minutes, a maximum of half an hour begins to break the whole body, as with severe chills: lower back, lower and upper abs, chest, almost unbearable pain occurs.
Then krepatura subsides and weakness piles up.
At the same time, the legs first weaken, then the arms and trunk.
The bitten turns pale, tears flow, he feels sick, his heart seems to will break out of the chest.
At the final stage, consciousness becomes cloudy. Man ceases to recognize surrounding and evaluate the situation, depressed, his paralyzes fear.
To prevent death, the victim needs inject serum is an antidote.
Important! Need to help the bitten in first 10, maximum 20 minutes.
In fairness, it is worth saying that karakurt is the first and simple so never attacks. He can bite, if by chance come to the nest or to the female herself
First steps
While walking around the neighborhood, carry matches in your pocket. If bitten black widow, the bite should be burned immediately with a match to destroy the poison formula.
Then you need to go to the nearest hospital and enter antidote. The serum itself is quite expensive.
It is produced at the Tashkent Institute of Vaccines and Serums and costs she is more than 30 thousand rubles.
Alternatively, you can introduce a 0.1% solution of potassium permanganate under the skin (5 ml) and make lotions.
Note that immediately after the injection, the poison does not neutralize. Is becoming it’s easier only after a week or three.
It all depends on the season, weight, age and immunity of the bitten and from the amount of poison injected under the skin.
But in fairness it’s worth saying that karakurts are the first and just never attack.
They can bite if they accidentally step on a nest or on the female herself.
