Länge bei der ersten Reifung / Größe / Gewicht / Alter
Geschlechtsreife: Lm ? range ? - ? cm Max length : 12.0 cm NG Männchen/unbestimmt; (Ref. 271)
Diagnostic features: Shell lightweight, deep-cupped inequivalve, left valve (attached) larger than right. Shell shape and outline variable. Inner margin smooth. Presidium transversally striated. Colour: externally dirty light grey, internally whitish or light grey splotched with bluish purple (Ref. 271).
It has a total length of 12 cm. Fisheries: It is heavily exploited due to over exploitation or contaminated by organic pollutants. It is consumed raw, fried, grilled or boiled. Canned industrially (Ref. 271). Attached to roots of Rhizophora mangle, rocks or other oyster shells. It is mostly intertidal or shallow-subtidal species (Ref. 271).

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.
