| The Brazilian wandering spider (Phoneutria spp.) or Armadeira (as it is known in Portuguese) is an aggressive and highly venomous spider named as such because it was first discovered in Brazil, though this genus is known to exist elsewhere in South and Central America. This spider is a member of the Ctenidae family of wandering spiders. Genera Phoneutria The wandering spiders used to refer to the genus Phoneutria but now usually refers to the entire family Ctenidae. ...
The Brazilian wandering spider appeared in the Guinness Book of World Records 2007 for the most venomous animal.
[edit] Phoneutria Phoneutria spp.(Greek for "Murderess") is actually a genus with five known similar species whose members are highly venomous. They include some of the relatively few species of spiders that present a threat to human beings. The Brazilian wandering spider can grow to have a leg span of up to 4-5 inches. It has been suggested that Snake poison be merged into this article or section. ...
These spiders are notorious both due to their toxic venom, and because they are not reluctant to attack people who appear threatening. Of the five species known, P. nigriventer and P. fera most frequently receive mention in mass-media publications. P.nigriventer species are responsible for most cases of venom intoxication in Brazil because this species is commonly found in highly populated areas of Brazil, namely the South-eastern states: São Paulo, Minas Gerais, Rio de Janeiro and Espírito Santo. The P. fera is native to the northern portion of South America, especially the Brazilian Amazônia, Venezuela and French Guiana.
Recent studies suggest that these spiders only inject venom in approximately one-third of their bites and may only inject a small amount in another third. However, research in this area is hindered by the difficulty of identifying particular subspecies.
Bites from these spiders may result in only a couple of painful pinpricks to full-blown envenomation. In either case, people bitten by a Phoneutria or any Ctenid should seek immediate emergency treatment as the venom is possibly life threatening. The Phoneutria fera and nigriventer are the two most commonly implicated as the most virulent of the Phoneutria spiders. The Phoneutria not only has a potent neurotoxin, but is reported to have one of the most excruciatingly painful envenomations of all spiders due to its high concentration of serotonin. Serotonin (pronounced ) (5-hydroxytryptamine, or 5-HT) is a monoamine neurotransmitter synthesized in serotonergic neurons in the central nervous system (CNS) and enterochromaffin cells in the gastrointestinal tract of animals including humans. ...
The wandering spider is so-called because it wanders the jungle floor, rather than residing in a lair or maintaining a web. This attribute is another reason it is considered so dangerous. In densely populated areas, Phoneutria species usually search for cover and dark places to hide during daytime, leading it to hide within houses, clothes, cars, boots, boxes and log piles; thus generating accidents when people disturb it. Regionally in the Mid-Atlantic US, this spider is sometimes known as the "Jerry's blue-fanged spider" because of the blue hair covering its lethal fangs. Its other common name - the "banana spider" - as attributed because it is occasionally found as a 'stowaway' within shipments of bananas. Genera Phoneutria The wandering spiders used to refer to the genus Phoneutria but now usually refers to the entire family Ctenidae. ...

Despite its reputation as the world's deadliest spider, there are multiple studies that dispute its capacity for fatal human envenomation. An antidote for its venom was developed by Carlos Chagas, in Brazil, but one study suggested that only 2.3% of bites (mainly in children) were serious enough to require antivenom.[1] However, other sources suggest it is the most dangerous or toxic spider in the world based upon toxicology studies. One of the most notable and thorough studies is presented in the book "Venomous Animals and their Venoms Vol. III" edited by Wolfgang Bucheral and Eleanor Buckley, and cleary demonstrate Phoneutria nigriventer's extreme toxicity in a table showing that the amount necessary to kill a 20gm mouse was only .006mg (intravenously) and .0134 subcutaneously as compared to Latrodectus mactans (Black Widow) at 0.110 and 0.2 respectively. The same study reports the death of two children killed by the same spider in São Sebastião (a coastal city near São Paulo, Brazil) identified as a Phoneutria, and identified by Bucheral. This demonstrates the fact that identification is key in the process of accurately associating a bite with the correct, offending species. Both P. nigriventer and P. fera are extremely dangerous. Pharmalogical studies strongly suggest the danger of Phoneutria envenomation and ranks various species of the Phoneutria genus arguably as one of the world's most dangerous spiders. Carlos Justiniano Ribeiro Chagas (born July 9, 1879, Oliveira, Minas Gerais, Brazil; died November 8, 1934, Rio de Janeiro), was a Brazilian physician. ...

Aside from causing intense pain, the venom of the spider can also cause priapism - uncomfortable erections that can last for many hours and that can lead to impotence. The venom may eventually be used in erectile dysfunction treatments.[2] Fresco of Priapus, House of the Vettii, Pompeii. ...
[edit] Keeping wandering spiders Spiderlings of this species eat flightless fruit flies and pinhead crickets, and may be kept in a clear plastic deli container with air holes. Adults require a 5-10 gallon tank, and eat crickets, other large insects, small lizards, and mice. Plus small birds, depends on the size. Image File history File links Emblem-important. ...
