Benthic; depth range 0 - 50 m (Ref. 348), usually 0 - 5 m (Ref. 348). Tropical
Indo-Pacific and Western Central Atlantic: from East Africa, to eastern Polynesia; north to Japan and south to Western Australia and Queensland.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 30.0 cm SHH male/unsexed; (Ref. 348); common length : 18.0 cm SHH male/unsexed; (Ref. 348)
Epibiotic (Ref. 104365). Found in reef areas of lagoons (Ref. 97298). Cemented to hard substrates. Mostly in intertidal and shallow subtidal levels to a depth of 5 m, but also to a depth of 50 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).
