Found in intertidal areas in sand; typical inhabitants of exposed beaches in the tropics and subtropics usually with other Donax species; are tidal migrants (Ref. 084495), are thus affected by changes in the beach profile due to erosion and accretion cycles brought about by the tides and by the monsoon seasons.

Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam.
