Found in the infralittoral zone (Ref. 101611). Intertidal; occurs in exposed rocky shores. Settles on rocks in the low-tide zone of channels (Ref. 106159). Associated with shore-mud bottoms (Ref. 106180). Attaches and forms aggregations on the aerial roots of mangroves such as Rhizophora mangle, Avicennia and Laguncularia (Ref. 101610). Adapted to estuarine waters (Ref. 101611). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).
