Signalment:Seasonal, mass die-off of Siliqua patula (Razor clams) on Kalaloch beach (Washington state).

History:Truncated age categories at one WA beach suggest that localized, pulsed mortality events are occurring after clams have recruited to coastal beaches. This mortality has led to extensive harvest closures at Kalaloch Beach, WA.

Gross Lesions:Multiple moribund clams
