Whether you're out in the wilderness or in your home, you're never that far away from a spider. However, there are so many different spider species, approximately 40,000 world wide, that it's hard to figure out which ones you need to worry about and which ones are harmless. In this gallery I rank the 10 most dangerous spiders in the world and provide photos of their bites (on the following slide). I based the rankings on how common the spider is, how aggressive it is and how deadly its venom is to humans. While everyone's immune system reacts differently to a spider bite (symptoms can range anywhere from pain and nausea to death) we should all be cautious of the following arachnids.
