Shell equivalve, moderately inflated and solid, oblong ovate and distinctly longer than high. Umbones moderately protruding, cardinal area rather narrow. About 21 radial ribs (19 to 23) at each valve; ribs quite narrow and sharp, distinctly rugose, bearing regular rounded nodules on the top. Periostracum rather thin and smooth.

Biology     Glossary (e.g. epibenthic)

On sand and mud bottoms. Intertidal and shallow sublittoral waters to a depth of 10 m (Ref. 348). 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).
