Santa Cruz, California is home to mountain lions, black widow spiders, and rattlesnakes. If you live here, you know there's a chance you might come across one of these deadly predators. But when your family’s in danger, animal control can be too slow. Even behind the safety of this steel shovel, homeowner Thomas Scott needs to be careful. Rattlesnake venom destroys tissue and causes crippling paralysis, sometimes leading to death. Unfortunately, this snake seems pretty attached to Thomas’ property. To protect his family, Thomas feels he has no choice but to take action. The snake’s head, severed from its body, continues to scan the area, waiting for an opportunity to strike. 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.
