These 12 Biggest Spiders are What Nightmares are Made of

Brazilian Wandering Spider

Not only is this spider huge, it is also venomous. In fact, this spider has one of the deadliest venoms of all spiders. On the bright side, it rarely kills humans. A spider bite would be extremely painful though. Despite the fact that its leg span is at 5.9 inches, it can easily make itself small and would love to hide in shoes. Next time, you think of something suspicious, check your shoes before wearing them!
