The Pacific scallop (Argopecten Purpuratus) is recognized by its fan-shaped shell and very robust valves. It’s worth noting that the left valve is more convex than the right, which is slightly smaller. The shell also features two lateral extensions, known as auricles, distinguished by the presence of radial ribs (24 to 26, a significantly higher number than in other scallop species). The internal organs are protected by the mantle, which houses a strong adductor muscle that enables the mollusk to move swiftly. The male gonad is white, while the female gonad is reddish in color. This species is commonly found in the waters of Peru and Panama. Particular attention is given to scallop aquaculture in Chile, where this mollusk is cultivated thanks to its high productivity, resilience and strength.

Pacific scallops are highly valued in the Southeastern Atlantic: just think that in Peru, where they are known as concha de abanico, they represent the main aquaculture export product.
