Yes they do ! They have a complete skeleton including skull, spine and rib-cage.
Your Skull, Rib Cage and Skin.
The rib cage needs to be flexible to allow for breathing and other movements of the torso. A solid sheet like the skull would restrict these movements and limit the expansion of the chest cavity during breathing. Additionally, the rib cage needs to protect the internal organs while allowing for some degree of mobility.
The rib cage offers better protection than the skull because it surrounds vital organs like the heart and lungs. The skull primarily protects the brain, whereas the rib cage provides a larger area of coverage for crucial organs.

The skeleton you are referring to is the axial skeleton. It includes the skull, rib cage, and vertebral column (backbone), which provides structural support and protects vital organs such as the brain and heart.
The axial skeleton consists of the skull, vertebral column, and rib cage.
The protective layer protecting our brain is our skull. For our hearts, we have the rib cage.
