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.
The brown recluse spider is one of the most dangerous spiders in the United States. Its venom destroys the walls of blood vessels near the site of the bite, sometimes causing a large skin ulcer. Research in 2013 revealed that a protein in the spiderâs venom targets phospholipid molecules, which make up a good portion of cell membranes, and transforms these molecules into simpler lipids.
