Abstract: Homing behavior of A. scabra (Mollusca: Gastropoda: Prosobranchia) from rocky shores was studied in field and laboratory. Populations residing 7.1 and 2.4 feet above MLLW showed no significant differences in homing ability. All size classed about 5-6 mm. in shell length showed equal homing abilities; smaller animals often did not exhibit homing. Scrubbing the substratum with a fiber brush, or treatment with 32% NaOH had no significant effect on homing tendency. Chiseling of the rock surface caused a drop in incidence of homing. This suggests that homing behavior is mediated through perception of the topography of the substratum, and is not a chemotactic response. Removal of the cephalic tentacles reduced the tendency to home, while removal of the eyes did not.
