A periwinkle is a univalve, specifically a type of gastropod mollusk. Unlike bivalves, which have two hinged shells, periwinkles have a single shell that is typically spiraled and coiled. They are often found in marine environments, particularly in intertidal zones. Examples include the common periwinkle (Littorina littorea).
