Diagnostic features: Shell rectangular, elongate (twice as long as wide), equivalve. Sculpture of about 20 to 30 irregular radial ribs, and fine concentric threads that cross-ribs and interspaces. Byssal gap present opposite to hinge, moderately narrow. Hinge long. Colour: creamy white, streaked with reddish to dark brown wavy bands. Periostracum brown and dense on fresh shells, covering colour pattern almost completely (Ref. 344).
Maximum size reported in Malacolog database was 9 cm in length (Ref. 83435). Epibiotic (Ref. 104365). It is found attached to the underside of rocks and coral heads by byssus (Ref. 344). Commonly forms dense beds on rocky bottoms at depths of 1 and 20 m (Ref. 121800)
Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
