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.
Females have a body length of about a centimetre, while the male is smaller, being only 3 to 4 mm long. The redback spider is one of few arachnids which usually display sexual cannibalism while mating. Redbacks are considered one of the most dangerous species of spiders in Australia. Its neurotoxic venom is toxic to humans, with bites causing severe pain, often for over 24 hours. An antivenom is commercially available, and since its introduction in 1956, no deaths due to redback bites have been reported.+.
