Does snake have skeleton?
Snake skeletons are not very complex because they do not have any appendages (limbs). A few species, such as boas and pythons, retain some vestigial structures similar to pelvic bones. In some species, these can even be seen externally and are called “spurs.” These structures are often used in reproduction. All other snakes simply have vertebrae, ribs, and a skull. Snakes can have between 130-500 vertebrae, with ribs attached to each one. This does not include the bones in the tail section, but only those that are anterior to the cloaca (analogous to the anus in mammals). A unique part of the snake skeleton is the makeup of the skull and teeth. Adaptations in the skull allow snakes to eat prey much larger than themselves. The bones are connected by elastic ligaments, allowing a lot of stretch. The joint of the upper and lower jaws is placed very posterior (far back) in the skull, allowing the mouth to open as wide as possible. Also, the bones of the lower jaw are not fused together at
