|P. fera from French Guiana|
Phoneutria fera is a species of spider in the family Ctenidae found in South America (Colombia, Ecuador, Peru, Brazil, Suriname and Guyana). It is commonly known as the Brazilian wandering spider, although this name is applied to other species in the genus Phoneutria, particularly Phoneutria nigriventer.
A study done at the Medical College of Georgia has found that venom from the Brazilian wandering spider contains a toxin, called Tx2-6, that causes erections. Scientists believe that combining this toxin with existing medication such as Viagra may lead to an effective treatment for erectile dysfunction.
