Snails have a mucus-laden, muscular foot adaptation, that flexes and contracts allowing for movement in water and land habitats, with the mucus layer preventing injury and friction along surfaces. Snails protect themselves from predators by taking coverage beneath their shells and through the use of the operculum, a door-like part that closes the opening of the shell. Although the relatively thin shell gives snails rather poor protection from determined or well-equipped predators, it does keep them from drying up when they seal themselves inside with the epiphram.
