Structure of the skeleton

Cervical vertebrae:

These are the vertebrae that make up the neck of the turtle. There are 8 bony parts to the cervical or neck region, which is short when compared to many other reptiles. The neck is said to be retractile although sea turtles cannot pull their heads fully back into their shells.The shortening of the neck in sea turtles is an adaptation to marine life.
