Maturity: L_m ? range ? - ? cm Max length : 41.1 cm SHL male/unsexed; (Ref. 117184); common length : 20.0 cm SHL male/unsexed; (Ref. 348)

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.

Collected for food and shell (Ref. 348).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Broadcast spawners. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
