The clam is a bivalve that includes many species. It has a shell that can vary from light gray to dark brown or display cream, brown or greyish hues, with striations and well-marked lines, presenting a characteristic lattice pattern. This mollusc lives on the sea bottom, near the coast, or on riverbeds and lagoons, buried in sand or mud. It feeds through filtration, with a diet of microalgae carried by currents, captured through a tubelike structure or siphon. It reproduces in summer.
