1. Tarantula Hawk
This is not a spider nor is it a bird, but rather it is a species of wasp that has such a sting that it can leave a man incapacitated and screaming in anguish. The pain lasts for approximately 3 minutes, but it is 3 minutes of the worst pain you would ever feel. The pain is so horrible that scientist’s advice to deal with it, is to lie down and scream.
