Inner surface of shell with shallow grooves corresponding to the external radial ribs. Internal nacreous layer rather thin, undivided, occupying the anterior 2/3 to 3/4 of valves. Posterior adductor scar completely enclosed within the nacreous area.

New Zealand populations are generally considered a distinct subspecies under the name Atrina pectinata zelandica (Gray, 1835). It is collected in many areas for food and fertilizer (Ref. 348). Minimum depth from 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.
