Biology     Glossary (e.g. epibenthic)

It has a total length of 5 cm (Ref. 271). Maximum depth range from Ref. 104365. Subtidal (Ref. 104487). It is found infaunal in sandy mud, in very low salinity brackish water (Ref. 271). Habitats have high water turbidity. Found in soft substrates which are a mixture of sand, mud and vegetation (Ref. 104487). In salt marsh (Ref. 104365). A non-selective filter-feeder which turns substantial quantities of plant detritus and phytoplankton into clam biomass. Also obtains nutrition from sediments via direct ingestion or by feeding on bacteria. Predators include fish, crabs, gastropods and ducks (Ref. 104240). Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833). Spawning is continuous throughout the year (Ref. 104339).
