Life History and Behavior
Common periwinkles use their foot to hold securely onto rocks or plants or whatever. periwinkles are herbivores, using their file-like tongue, the radula, to feed on diatoms and algae attached to intertidal rocks. The common periwinkle breaks down its food by mixing it with mucous on the radula before bringing the food into its mouth. Sea stars, whelks, and some fish eat common periwinkles. The shells of dead common periwinkles are often inhabited by hermit crabs.
