Hog-nosed snakes will feign death by rolling on their backs, and when rolled upright will roll back again as if to insist they're really dead.
Hog nosed snakes are snakes found in North America. They are stout with upturned snouts and are best known for their distinct behavior when threatened. When threatened, the hog nosed snake will flatten its neck and raise its head off the ground and hiss, in an attempt to scare off the threat.
If this doesn’t work, the snake rolls on its back and plays dead with the mouth open and tongue lolling, even emitting a foul smell. If one were to roll it back onto its belly, it would respond by rolling back onto its back, trying to sell the impression that it is truly dead. Sadly, it seems they’re no possums in the world of playing dead.
