The razor shell, Ensis magnus, also called razor clam, razor fish or spoot (colloquially), is a bivalve of the family Pharidae. It is found on sandy beaches in Canada and northern Europe (north of the Bay of Biscay).
In some locations, the common name "razor shell" is also used to refer to members of the family Solenidae, including species of the genera Ensis and Solen, by some taxonomic classifications which include the family Pharidae within the family Solenidae. It prefers coarser sand than its relatives E. ensis and E. siliqua.
