A Prosser, Washington man learned the hard way the fact that the severed head of a rattlesnake remains capable of biting for a long time after being separated from its body. The old-timers in rural Pennsylvania always swore that a snake couldn’t die before sundown. I doubt that sundown has anything to do with it, but there is no doubt that the body of a decapitated snake will twist and coil for many hours and a decapitated snake’s head can definitely continue to bite for a very long time.

In this case, the perpetrator was probably the Western rattlesnake (Crotalus viridus).
