There are several species of scallops on the west coast, and all are subtidal.  Species most commonly encountered by SCUBA-divers are the spiny and smooth species of Chlamys, the permanently attached giant rock scallop Crassadoma gigantea, and (occasionally) the deeper-dwelling giant weathervane scallop Patinopecten caurinus.  All 3 motile species have been overfished and are becoming rare, but markets are developing for cultured scallops, particularly the spiny scallop Chlamys hastata

NOTE  the word “scallop” derives from the Old French “escalope”.  Earliest listings in English literature are references in the 1400’s to “scalop fysches”
