Who. Phoneutria. Where. Brazil Brazil. The world's most venomous spiders are the Brazilian wandering spiders of the genus Phoneutria, and particularly the Brazilian huntsman Phoneutria fera, which has the most active neurotoxic venom of any living spider. Its venom is so potent that only 0.006 mg (0.00000021 oz) is sufficient to kill a mouse. Phoneutria spiders are usually dark in colour and have a body-and-leg spread of approximately 17 cm (6.75 in). These large and highly aggressive creatures often enter human dwellings and hide in clothing or shoes.
Of those that are considered toxic, only the Brazilian wandering spider, the funnel web spiders, some of the widow spiders, the Chilean Recluse spider and the Chinese bird spider, which is a type of tarantula, have caused fatalities. The bites are much more dangerous to small children and the elderly.
