When it comes to snakes, people will immediately think of a dangerous animal with deadly bites. When feeling threatened, most snakes often give warning signs such as swollen gills or tail vibrations to warn the opponent that it may attack at any time. It is also because of their dangerous venom that they have used their venom to hunt as well as defend through bites or in some species can spray venom into the air.
However, with the snub-nosed snake, officially known as the North American Hognose snake, and the zombie snake, things are completely different. They are a fairly gentle snake, non-venomous and completely harmless to humans. Therefore, in order to protect themselves from dangerous enemies in nature, they have chosen to fake their deaths and emit stench to deceive the opponent.
When in danger, this snake will fake death by opening its mouth, rolling and writhing for a while before lying on its back to signal that it is dead. It can even stop breathing, give off a terrible smell to increase the persuasion of death. Of course, after the enemy is gone, it will crawl again quickly to escape. From a scientific point of view, the above action of the Hognose snake is actually a defense mechanism of it and it is indeed very effective.
