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.
