Brazilian Wandering Spider
This spider is the most venomous spider in the world according to the Guinness Book of World Records. The main reason it’s so dangerous is in its name – it tends to wander everywhere. They are found typically hiding in houses and cars as well as densely populated areas, especially during the day.
Hippopotamus
While hippos are mostly herbivorous, they also happen to be very aggressive and are known as one of the most dangerous animals in Africa. They’ve been known to attack humans for no reason to the point of destroying entire cars.
