what is the most venomous spider?
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.
The Brasilian wandering spider is not only the worldâs most venomous spider-as ranked by Guinness World Records in 2010- but it is an aggressive one too. These combined features of toxicity and aggressivity allow us to name this spider the most dangerous in the world.
