Let's be honest, Idaho's full of animals that you don't want to go toe to toe with. 

Grizzly Bears. Mountain Lions. Wolves. The idea of being attacked and mauled by any of those things is terrifying. In some cases, they could easily kill you. In others, you'll likely come out of that fight disfigured, scarred and/or dealing with painful injuries for quite a while. We don't mean to be morbid, but in these situations at least you knew what happened.

You may not realize that those bites happened until it's too late.

All of these critters' bites can be potentially fatal to humans. Read on to find out why!
