Observations were made on the tidal rhythmic activities of two Japanese limpets, Siphonaria japonica (Pulmonata) and Patelloida saccharina lanx (Prosobranchia) which live in the intertidal zone in the vicinity of the Seto Marine Biological Laboratory in the Kii Peninsula. Both species show rhythmic homing with correspondence to the tidal rhythm. At spring-tide, they creep about near the home "scar" twice during a tide, i.e., just before they are exposed to air and immediately after being submerged in water. During neap-tide, when their habitats remain submerged throughout the day, they move only once at the time of low tide. It must be noted the similarity of behavior patterns in these two phylogenetically different limpets seems to me to be caused by the convergence in activity patterns.
