The giant desert centipede appears to be a bite, but it's actually a pinch from a pair of modified hollow legs near the centipede's head. When the centipede pinches, it injects venom that causes intense pain. It has been described as feeling like nothing more than a honeybee sting and, at the other end, as Peterson says, it "could potentially rot a hole in [his] arm." For Peterson, it was the latter. It looks horrible, even though the giant desert centipede isn't known to cause death in humans.
Nonetheless, from Peterson's writhing, it's clear this is an intensely painful experience. "This is so much worse than a bullet ant sting," he yells while rolling on the ground. "This just absolutely eclipses all the insect stings I have taken." The video ends with a bit of a cliffhanger, with Peterson asking for the cameras to be cut. We'll update this post with the second video when it's released.
