Composition of developmental stages of A. shiranui and H.matsumurai of each aggregation (G1–G7) formed on tidal pools or along the seashore at varying distances from the waterfront edge of the tidal flat. A: the total number of A. shiranui and H: the total number of H. matsumurai at each aggregation.
