Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 11.0 cm TL male/unsexed; (Ref. 271)
Shell mussel-shaped, trigonal, thin. Sculpture of fine growth lines. Umbones swollen, not terminal (away from pointed end of shell). Hinge teeth absent. Periostracum heavy, sometimes hair-like. Colour: externally light brown with blush of rose, purple or orange (concentrated on umbones) and purple streaks, but with a white oblique streak in the middle of shell, internally pearly whitish, tinged with rose or purple (Ref. 271).
It is attached to hard substrates intertidally or at shallow subtidal depths, mostly in coral reef areas (Ref. 271).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
