“Rattlesnake venom destroys tissues and causes crippling paralysis, sometimes leading to death. When Santa Cruz homeowner Thomas Scott encountered such a deadly predator in his garage, he took defensive matters into his own hands. However, unlike mammals, reptile reflexes remain deadly after death. In fact, they can still bite and deliver a killing dose of venom up to an hour after being decapitated. And after Thomas delivered what he thought was a deadly blow, the snake’s head–severed from its body–continued to scan the area, waiting for an opportunity to strike.”
That’s some straight nightmare fuel video over at NatGeo. You’ve been warned.
