The wandering spiders (or running spiders in Europe) is a term used to refer to the spider family Ctenidae. Previously the term referred only to the genus Phoneutria but now usually refers to the entire family Ctenidae. The members of the genus Phoneutria are highly aggressive and venomous nocturnal hunters and are the only wandering spiders known to pose a serious danger to humans.
