An interesting fact about the neck of a giraffe

Most people are surprised to learn that the incredibly long neck of a giraffe is supported by just seven cervical vertebrae - the same number as in humans (and I think most other mammals).  The unusual length of the vertebrae is demonstrated nicely in this photo.
