Until now, researchers were able to identify about 40,000 species of spiders classified into 109 families. Being extremely interesting, with considerable experience on Earth, spiders have always fascinated and continues to fascinate people and today. Of particular interest are species of spiders enjoy potentially dangerous to humans. Between all these genres, emerges from the multitude of deadly arachnids spiders of the genus Phoneutria, and among them stands Phoneutria Potiphera terrible – the most venomous spider in the world.
When death is under 5 inches …
Phoneutria nigriventer or Brazilian hobo spider, as the fans called arachnids, is the most dangerous and poisonous spider on earth. Yes, we know we mentioned this, but the spider in question is potentially lethal so scary that this aspect should be mentioned as often among all articles that deal.
In fact, none of the 8 species of spider of the genus Phoneutria (the name inspired! – Means killer in Greek) is not suitable for pet shops or private collections of fans of arachnids. Brazilian tramp any accidental escape can turn into a tragedy, or even more, given the aggressiveness of these native species.
Somehow improperly called homeless “Brazilian” Phoneutria spiders live throughout the tropics of Central and South America. All the information for fans, spiders belong to the family Ctenidae stray and homeless names were pulled from their habits. Vagrants Brazilians are particularly active at night, when, unlike other spiders stretching their webs and wait patiently to drop prey, they roam the land in search nenorocoaselor tireless victims.
During the day, Phoneutria genus spider hiding inside termite mounds, under fallen trees or rocks truchiuri. One species, Phoneutria nigriventer, is feared for his habit of frequent dark and damp places located near human settlements. Is also known as the “banana spider” under its habits to hide in bunches of bananas. Terrible representatives of the genus Phoneutria are like tarantulas, despite the temptation to resemble giant hairy spiders.
On the contrary, their appearance is relatively modest compared to the potential death to be submitted. Tarantulas are generally for people inofesive are ambush hunters, unlike Brazil, which follow their bums and “run” on its prey.
Body length ranges of these spiders între17-48 mm and can reach 13-15 feet scale inches. For fans, it is worth noting that Phoneutria spiders are easily confused with those of the genus Cupiennius, both types showing reddish hairs on the abdomen. Brazilian eight eyes, like most arachnids, of which two are larger than the rest. Have hairy legs and strong, and their chelicerele completed in “fangs” host glands containing one of the most toxic venoms present in the animal world.
When they feel threatened by any danger, their role chelicerele jaws are red, like the fury of arachnids, and are exposed to visible as a clear sign the final warning before the attack. Have a great visual as well as tracking all predators that feed on active prey. Guinness Book Champion of pages
Potiphera Phoneutria spider species was recognized by experts as the most venomous spider in the world, appearing with the title and the 2012 edition of the prestigious Guinness Book of World Records.
For lovers of exotic travel should be noted that representatives of the genus Phoneutria temuţii live in forests and wetlands in the Dominican Republic, Costa Rica, northern Argentina, Colombia, French Guiana and Guyana Republic, Ecuador, Peru, Bolivia, Paraguay and, of course, Brazil , state that hosts the highest populations of these arachnids. Have been reported recently in Chile and Uruguay, most likely being introduced to people. Their most important attribute is obviously poison!
The most dangerous species venom contains a neurotoxin P. Potiphera extremely strong, called PhTx3. Once imbued with prey or human body, the toxin acts as a calcium channel blocker, glutamate and calcium dynamics affecting the neuronal synapses. The venom causes intense pain and swelling due to a stimulating effect on serotonin 5-HT4 receptors of sensory nerves.
This sensory nerve stimulation leads to release of neuropeptides that trigger inflammation and agonizing pain. In concentrations lethal neurotoxin causes loss of muscle control and breathing difficulties, leading to paralysis and death by asphyxiation.
Based on experiments on laboratory mice showed that hobo spider venom Brazilian is more powerful than the black widow spider. Once a homeless Brazilian bitten a human adult, it dies within 2-12 hours depending on the amount of venom that the spider started to inject the teeth that are equipped chelicerele. Finally, in addition to asphyxia, the victim suffers a fatal heart attack.
The most dangerous spider and unwanted erections
Although “most deadly” spider in the world, the risk to humans is not necessarily related to power venom. A recent study found that stray spiders inject venom in only one of three bites, arachnids being very careful with the waste discharge, precious to them because its production requires energy. In addition, oral valve is suitable for small prey, not to attack large mammals (such is man).
The real danger is related to the active traveler of these spiders, in combination with human populations spreading and thickening. In areas densely populated by humans, spiders seek shelter during the day in places where accidental contact with people is just a matter of time. Ducking into the sunlight, hiding inside houses, the apartments and cars, in clothes and footwear, warehouses, garages, wood piles.
Live, on average, between 1-2 years and is most visible during mating, ie from April to June. How not hunt with a traditional canvas, female hobo spider silk secreted Brazilian uses to manufacture some “bags” that store their eggs. The bags are then stored in places Acuna, where chicks hatch in relative safety.
An unexpected effect of the bite of these spiders, where the human victim is a man, is the state of priapism (priapism is a sexual disorder is quasi-permanent erection, unnatural and painful). Erections caused by bites are extremely uncomfortable, lasts for hours, and if one escapes life may remain impotent. The venom contains nitric oxide which acts as a potent dilator agent of veins and arteries, followed by increased blood flow into the penis, painful erections manifested endless.
“Erections side effects that affect all victims [male, no] bitten by stray spiders. Are unbearably painful, and the victims are going through difficult times. Now examine spider venom to synthesize a drug effective and safe in treating cases impotence, “says researcher Romulo Leite of the Medical College, Georgia State.
How science has not yet synthesized miracle drug made from the most dangerous spider venom nor created a serum effective against bites, Phoneutria Clan chelicere knights must remain in their environment.
And if you go among the people, provided they are kept must comply with all the most rigorous safety rules required for such potentially dangerous animals.
