How Do Snails Make Their Shells?

Snails are invertebrates, their body is divided into two parts: the head, which has a shell, and the rest of the body. The snail's shell is made up of layers of chitin, a tough material that is similar to what makes up the exoskeleton of insects.

The snail grows this shell by adding new layers as it eats. When the snail molts, it removes its old shell and replaces it with a new one. The process of making a new shell starts with the snail-eating something hard. This hard substance is what the snail uses to make its first layer of the new shell. 

Once this first layer is built up, the snail begins to eat softer substances. These substances help to form the second and third layers of the new shell. When all three layers have been built up, the snail molts and discard its old shell.

The process of making a new shell is not just limited to snails. Almost any invertebrate can grow a new shell.

Snails are one of the most common creatures on earth, and their shells are incredibly important to their survival. Snails can grow their shells by adding new layers as they eat, and the process of making a new shell is not just limited to snails. Almost any invertebrate can grow a new shell.
