Pacific razor clam

Siliqua patula

Classification

Family
Pharidae

The Pacific razor clam, Siliqua patula, is a large mollusc native to North America belonging to the family Pharidae. Pacific razor clams are sexually dimorphic, but as with all clams, there is no way to tell the difference between sexes without dissecting them or evaluating them under a microscope. The shell ranges in colours as the clams grow, starting out brown, and turning to a more yellow colour as the clam matures, eventually turning brown once more as the clam reaches a larger size.
