Are snakes all neck or all tail?

Despite obvious differences in size and shapes observed among different vertebrate animals, they all have bodies with a head and neck, a trunk and a tail. It is the relative size of each of these body sections what makes a large part of the body differences among these animals.

Do fish have necks?

Although fish lack a true, anatomical neck, studies of their feeding suggest the backbone could function as a neck by bending upwards to lift the head away from the body. If fish do have a hidden “neck”, it is powered by the body muscles, which extend from head to tail in a complex architecture of muscle fibres.

Does snake have a backbone?

All snakes are vertebrates, which means that they all have backbones . In fact, snakes have more backbones (or vertebrae) than any living mammal. In a snake’s body, many tiny backbones are connected by hundreds of joints and a strong network of muscles, which is what gives snakes their extreme flexibility.

Do snake have bones?

Snakes have a lot more bones than we do, but they have a lot fewer types of bones. Aside from a few boas, pythons, pipesnakes, and blindsnakes with vestigial femurs, most snakes just have a few hundred vertebrae with one pair of ribs each (except in the neck & tail), and a skull. The snake skull is a remarkable structure.
