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)
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).

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.
