Pacific razor clam

The Pacific razor clam, Siliqua patula, is a species of large marine bivalve mollusc in the family Pharidae.

[4] It is similar to the smaller Atlantic razor clam, Siliqua costata, which is found on the East Coast of the United States.

Pacific razor clams are a highly desirable shellfish species and are collected by both commercial and recreational harvesters.

[6] Harvesters should check current public health recommendations by marine authorities before collecting razor clams.

[8] Some clams expose their siphons as the surf is receding making them far easier to spot; this behavior is called "necking".
