If we should see a snake, the plan was simple: Stop the truck, bail out, grab the snake, wrestle it into submission, and then stuff it into a laundry bag. Booth stressed that it was important not to get bit by a large snake. Pythons have rows of needlelike teeth that curve back toward their gullets. If a large snake clamps on to an arm or a leg, it instinctively coils around it's victim and starts to constrict. In prey animals this constriction causes cardiac arrest, and almost certain death. But if a large python were to constrict around the arm or leg of a human, that limb can go numb in pretty short order, Booth says. And if you're fighting a big python and lose use of an arm, things will turn bad pretty quickly.
