Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 9.0 cm DL male/unsexed; (Ref. 83435); common length : 10.0 cm TL male/unsexed; (Ref. 344)
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.

Assumed common length is 10 cm (Ref. 344). Epibiotic (Ref. 104365). It is found attached to the underside of rocks and coral heads by byssus (Ref. 344). 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).
