维基百科 Phoneutria, commonly known as Brazilian wandering spiders, armed spiders ("armadeiras", as they are known in Brazilian Portuguese), or banana spiders, are a genus of aggressive and venomous spiders of potential medical significance to humans. They are mainly found in tropical South America, with one species in Central America.[1] These spiders are members of the Ctenidae family of wandering spiders. The Brazilian wandering spiders appear in Guinness World Records from 2010 as the world's most venomous spider. Guinness World Records states that although the Brazilian wandering spider venom is the most toxic, an effective antivenom is available and few fatalities occur.[2][3]
