How does a snail support itself with no skeleton inside body?

Snails have a hard outer shell that provides support and protection for their soft bodies. The shell is made of calcium carbonate and is secreted by the snail's mantle, which is a layer of tissue that covers the snail's body. The shell grows as the snail grows, and it is constantly being repaired and strengthened.

In addition to the shell, snails also have a hydrostatic skeleton. This means that they have a fluid-filled body cavity that helps to support their bodies and allows them to move. When a snail contracts its muscles, the fluid in the body cavity is forced into different parts of the body, which helps to change the snail's shape and allows it to move.

The combination of the shell and the hydrostatic skeleton gives snails the support they need to move around and to protect themselves from predators.
