Vertebrate. Though very flexible,snakes have many vertebrae (small bones that form the backbone).

What kind of skeleton does snakes have?

With no arms or legs, a snake has a simple skeleton. The skull is connected to a long, flexible spine (or backbone), with hundreds of ribs running down to the base of the tail. This allows the snake to bend and curl its body as it pushes against the ground to move along.

Do snakes have more vertebrae than humans?

The segmentation process also helps establish some key differences in the body plans of different organisms: while humans have 33 vertebrae, frogs have 10 or fewer, and snakes can have more than 300. Snakes, fish, chickens, and humans all begin life in much the same way.
