Siliqua patula, more commonly known as the Pacific razor clam, is a meaty shellfish with a narrow, oblong shell. In Washington, these clams can grow to a length of three to six inches. They are found primarily on the intertidal coastal beaches. The Washington Department of Fish and Wildlife divides the harvest areas into five major management zones:
During one season, Washington's recreational razor clam fishery sees more than 280,000 digging trips with individuals harvesting as many as 4 million Pacific razor clams for the season. A shellfish/seaweed license, combination license, or razor clam license is required for harvesting razor clams.
The Siliqua patula, or Pacific razor clam, is designated as the official clam of the state of Washington.
