Abstract: 1. Tonicella lineata characteristically occurs on a coralline algal substratum. 2. Coralline algae comprise an average of more than 50% of its diet. 3. Subtidally, Tonicella lineata exhibits increased activity nocturnally. Intertidally, heightened activity coincides with periods of high water. 4. Indications of homing behavior were observed in some intertidal and subtidal individuals. 5. Intertidal and subtidal populations of Tonicella lineata differ in body size, color, activity pattern, and number of valve notches.
