Aequipecten opercularis, commonly known as the Queen Scallop, is a bivalve mollusc from the family Pectinidae, prevalent in the coastal waters of the Comunidad Valenciana and other European seas. This species is highly regarded for its culinary value and ecological significance.

The Queen Scallop is recognized by its distinct fan-shaped shell, which can have a variety of colors, including hues of red, yellow, and brown. These shells usually exhibit radiant bands or striations that add to their beautiful appearance and are responsible for their widespread collection as decorative items.
