#15 Tarantula Hawk
Most believe that tarantula spiders are invincible but, while they are dangerous, they have an even stronger enemy— the Tarantula Hawk, a spider-hunting wasp.
This fearsome wasp ranks at four in the Schmidt Pain Index, which is the most painful level. It has a debilitating, burning sting that numbs all other pain in your body.
If tarantulas are there, this wasp won’t be far away. They’re here for spiders and, unless you threaten them, you’ll be spared their agonizing sting.
