Short description Morphology

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.

Biology     Glossary (e.g. epibenthic)

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).
