Many species of gastropods have a more or less large outer shell: atrophied in slugs, it is large enough to shelter the whole animal in snails for example; it then constitutes protection against predators and drought. These shells, called univalves, have special features compared to the shells of other molluscs. They are optional or compulsory calcicole (limestone obtained in the plants on which they feed or by scraping the calcareous mineral substrates), more rarely calcifuge and in regions with non-calcareous soil can chew the shell of other individuals (case of parasitism), bone, eggshells. The shell is secreted by a thick fold of skin, called the mantle. It is mainly composed of calcium carbonate. Gastropods therefore need a diet rich in calcium.
