Donax denticulatus Linné occurs in the intertidal zone of sandy beaches throughout the West Indies. It is highly specific with regards to the nature of the substratum and lives almost entirely in the saturated wash zone of the beach. To maintain their pattern of zonation, clams migrate synchronously with the tides, a process which is made possible by the mobility of the siphons and foot. Enormous populations sometimes develop, and different populations may show wide variations in their density, size of individuals, and color of shells. The distribution of populations is influenced by the nature of the beach sand, its size and sorting, the slope of the beach, the degree of wave exposure, and the organic content of the sand. Biotic associations include predation, parasitism, and commensalism.
