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.
One of the smallest and most venomous spiders in the world is the black widow spider. The venom in a black widow spider is 15 times more deadly than a rattlesnake, but luckily, the spider will only bite in self-defense. One of the largest dangerous spiders in the world is the Northern funnel web spider. It lives in Australia and can grow to be more than 3 inches long. It lives in trees, is attracted to water and can sometimes be found in swimming pools.
