About Razor Clams (Siliqua Patula) in Washington State

The Pacific razor clam (Siliqua patula) is an exceptionally meaty shellfish which ranges from California to Alaska. It is abundant on surf-pounded ocean beaches, but also occurs in sheltered areas along the coast. Limited diving observations have indicated some adult razor clams (S.patula) offshore for up to one-half mile. Razor clams dredged in water deeper than 30 feet, although similar to the beach clam, are a different species (Siliqua sloati).

In Washington waters, the razor clam grows to a maximum length of six inches, although they are seldom found. Clams seven inches long have been recorded, but are very rare. In contrast, razor clams found in Alaska may grow to eleven inches in length and live to be 15 years old, due to colder water temperatures and slower growth rates.

Razor clams are found primarily on the intertidal coastal beaches (those that are exposed at low tide) from a +3 foot level to a -2 foot tide level. The Washington Department of Fish and Wildlife (WDFW) divides the harvest areas into five major management zones (see map):
