The image on the right shows the standard biological classification system that is used to classify all life on Planet Earth, including the many types of snakes. What are the biggest types of snakes? Snakes can control the amount of venom they inject and may bite aggressively for food or defensively for protection.
This is one of the things that make them so interesting. Moltingor ecdysisserves a number of functions. This causes the old skin to separate from the new skin beneath it.
The skull of the snake consists of a solid and complete neurocraniumto which many of the other bones are only loosely attached, particularly the highly mobile jaw bones, which facilitate manipulation and ingestion of large prey items.
As you can see, there's a lot of diversity among the different types of snakes. In many cases, the cast skin peels backward over the body from head to tail in one piece, like pulling a sock off inside-out.
