Ecology of Asaphis violascens

Main Ref.	Bernard, F.R., Y.Y. Cai and B. Morton, 1993
Remarks	Littoral and sublittoral to a depth of about 20 m (Ref. 345). Found in intertidal areas in sand (Ref 75831). Deeply buried in sand, often coarse to gravel bottoms (Refs. 345, 126564). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).
