Biology     Glossary (e.g. epibenthic)

Minimum depth from Ref. 101279. Maximum depth recorded is 329 m (Ref. 101279). Lives in burrows in sand, mud, sandy mud and sandy gravels from the mid shore to the shallow sublittoral, sometimes to a depth of 192 m (Ref. 78574). Commonly found in estuarine areas, buried in substrate 10 to 20 cm deep (Ref. 95344). In the Vainameri (north-eastern Baltic Sea), abundant in silty substrate (Ref. 95753). Deposit/filter feeders (Ref. 95728). Identified as an ecologically important benthic species of the Baltic Sea, mainly as part of the food base of fishes and its contribution to biofiltration and biosedimentation processes (Ref. 95774). A microvore that feeds on organic detritus (Ref. 96352). Found both in intertidal mudflat and estuary (Ref. 2823). 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 (Ref. 833).
