15. Brazilian Wandering Spider
According to the Guinness Book of World Records, this is the most venomous spider in the entire world. That’s quite a title to live up to, and the Brazilian Wandering Spider does it well. They got their name because of their tendency to do just that: wander.
The Brazilian Wandering Spider has a habit of crawling into cars, houses, and other densely populated areas, especially during the day time. With human beings crossing paths with the Brazilian Wandering Spider so often, it’s not wonder that it’s one of the most dangerous animals in the world.
