Bivalvia | Veneroida
Environment / Climate / Range
Benthic. Tropical; 23°C - 30°C (Ref. 102835); 13°N - 9°S, 109°E - 139°E (Ref. 106696)
Western Central Pacific: Restricted in the tropical western Pacific. From Sabah, Malaysia to Palau, north to Philippines and south to Indonesia.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 40.0 cm SHL male/unsexed; (Ref. 348); common length : 20.0 cm SHL male/unsexed; (Ref. 348)
Its shell is thinner and smoother than that of H. hippopus, usually devoid of pigmentation, and more semi-circular in profile. The mantle is similar to that of H. hippopus (Rosewater, 1982), except that prominent papillae line the margins of the incurrent siphon.
Collected for food and shell (Ref. 348). Found in shallow waters. Young specimens often byssally attached to coral heads, mature specimens lack a byssus and lay unattached on the substrate (Ref. 348). Broadcast spawners. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
