A Mexican Hog-nosed Snake is found stretched out on a road. It goes into a defensive coil, smearing its feces on itself and hissing and striking, before crawling away and down a hole. A Mexican Hog-nosed Snake blows and hisses and strikes. Hog-nosed snakes are well-known for their strategy of rolling over and playing dead to dissuade a predator. This one rolls over and plays dead, then uses a combination of playing dead and hissing.
