Spiders are often feared for their creepy crawly nature and their venomous bites. But while all spiders produce venom, only a few species are poisonous enough to be considered dangerous to humans. Here are some of the most poisonous spiders in the world:
Brazilian Wandering Spider (Phoneutria fera and Phoneutria nigriventer): This spider is considered by Guinness World Records to be the most venomous spider in the world. Its venom is a potent cocktail of neurotoxins that can cause muscle paralysis, respiratory failure, and even death.
Sydney Funnel-Web Spider (Atrax robustus): This Australian spider is known for its aggressive behavior and its fast-acting venom. Its bite can cause severe pain, muscle spasms, and vomiting, and can be fatal if not treated immediately.
Black Widow Spider (Latrodectus mactans): The black widow spider is one of the most recognizable spiders in the world, thanks to its hourglass-shaped marking on its abdomen. Its venom is not as potent as that of some other spiders on this list, but it can still cause severe pain, muscle cramps, and nausea.
Brown Recluse Spider (Loxosceles reclusa): This spider is found in the southern and central United States, and its bite can cause a necrotic lesion that can destroy tissue and leave a permanent scar.
Six-Eyed Sand Spider (Sicarius hahni): This spider is found in southern Africa, and its venom is cytotoxic, meaning it can destroy cells. Its bite can cause severe pain, swelling, and tissue death.
