Here are some adaptations that are typical of most terrestrial snails, not just specific to S. exodon.

One of the most basic and recognizable forms of protection in snails is their shell. These diverse forms that cover the body of snails are made of calcium carbonate (Hickman et al. 2012). The shells of snails are covered in a protein that is able to protect the calcium from erosion and the shells get thicker as the snail grows (Hickman et al. 2012).

The shells of snails also contain an operculum which is a plate that can cover the opening of the shell if the body is pulled inside. The operculum is used for protection and helps prevent water loss (Hickman et al. 2012).

Most mollusks contain a structure in their mouths called a radula (Hickman et al. 2012). A radula is a tongue-like organ that contains a membrane filled with tiny teeth that are able to scrape, cut, tear or pierce food particles (Hickman et al. 2012). The radula also has a retractor and protractor muscle that allows it to be moved in or out of the mouth (Hickman et al. 2012).

Snails are believed to be one of the first animals to become terrestrial (Hickman et al. 2012). Evolving from water to land animals required the development of lungs instead of gills to breathe (Hickman et al. 2012).

One of the most interesting adaptations that snails have undergone through evolution is torsion of their body within their shell. Torsion occurs during development and allows snails to have only one opening in their shell for easier protection (Hickman et al. 2012). Through the process of torsion, the body is twisted 180° within the shell allowing the mouth and the anus to exit the shell at the same point (Hickman et al. 2012).
