Snails have shells, and a shell is a type of skeleton (an exoskeleton).
All snails have only a shell for a skeletal system.
Snails are invertebrates. They carry their "skeletal system" (exoskeleton) on the outside in the form of their shells, they do not have internal bones. Vertebrates have internal skeletal systems with a spine and vertebral column.
Snails use their shell as the primary structure for their muscles to attache to. this provides a rudimentary skeletal support system.
The skull belongs to the skeletal system.
The skeletal system itself is an organ system. Some schemes combine the skeletal system with the muscular system to make the musculoskeletal system.
The skeletal system are your bones.
