Snakes can still move for some time after being decapitated, because the nerve cells in them [heat sensitive pits] located in their head do not lose function immediately upon death, but allows the snake to sense prey and strike. Also the Louisiana Department of Wildlife and Fisheries website confirmed that “involuntary nerve activity” of a dead snake could continue for hours. Copperheads are actually venomous, but their bites are rarely fatal to humans.
