The shells of a few species of large sea snails within the Vetigastropoda have a thick layer of nacre and have been used as a source of mother of pearl.
Land snails have been eaten for thousands of years, going back at least as far as the Pleistocene. Archaeological evidence of snail consumption is especially abundant in Capsian sites in North Africa , but is also found throughout the Mediterranean region in archaeological sites dating between 12,000 and 6,000 years ago.
Snails cannot absorb colored pigments when eating paper or cardboard so their feces are also colored. [3] Several species of the genus Achatina and related genera are known as giant African land snails; some grow to 38 cm (15 in) from snout to tail, and weigh 1 kg (2 lb). [4]
Some saltwater limpets such as Trimusculidae breathe air, and some freshwater limpets are descendants of air-breathing land snails (e.g. the genus Ancylus) whose ancestors had a pallial cavity serving as a lung. In these small freshwater limpets, that "lung" underwent secondary adaptation to allow the absorption of dissolved oxygen from water.
