Morphologie
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.
