Fig. 3. Shell lengths of Patelloida saccharina and Siphonaria guamensis (mean + S.D.) measured during low tide along the tidal gradient in Phraae and Sunset beach. Sample sizes at each tidal height are shown on the x-axis. Different letters indicate significant variation in shell length between tidal levels (uppercase for P. saccharina and lowercase for S. guamensis). Results were retrieved from post-hoc comparisons (p <0.05).
