Phoneutria fera is a species of spider in the family Ctenidae found in South America (Colombia, Ecuador, Peru, Brazil, Suriname and Guyana).[1] It is commonly known as the Brazilian wandering spider, although this name is applied to other species in the genus Phoneutria, particularly Phoneutria nigriventer.[2]


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.[3]
