Is a land snail gastropod or a bevalve?

A land snail is a gastropod, which is a class of mollusks characterized by their single, usually spiraled shell and a distinct head with tentacles. In contrast, bivalves are a different class of mollusks that have two hinged shells and primarily include species like clams and oysters. Gastropods exhibit a wide variety of forms and habitats, including terrestrial environments, whereas bivalves are mostly aquatic.
