Some non venomous snakes like pythons, blind snakes and file snakes are solid toothed that is they don't deliver venom when they bite. These non-venomous snakes employ different techniques to kill their prey for example boas asphyxiate their prey with their large bodies. In fact in pre-historic times the large boas were the predominant species of snake and some times measure up to 25m! |
