Photomicrograph of radula of periwinkle showing teeth like ridges
The common periwinkle is primarily an algae grazer, but will feed on small invertebrates such as barnacle larvae. They use their radula to scrape algae from rocks, and, in the salt marsh community, pick up algae from the cord grass, or from the biofilm that covers the surface of mud in estuaries or bays.
