EOL Text
Ensis is a genus of medium-sized edible saltwater clams, littoral bivalve molluscs in the family Pharidae. Ensis or razor clams are known in much of Scotland as Spoots, for the spouts of water they eject while burrowing into the sand, when visible at low tide.[2] This term may also colloquially include members of the genus Solen. Ensis Arcuatus are known as Bendies due to their slightly curved shell

Description[edit]
The shells are long, narrow, and parallel-sided. This shape resembles a closed, old-fashioned straight razor (a cut-throat razor), or a closed jackknife (pocket knife) and sometimes these clams are known as razor shells or jackknives. The shells in these species are fragile and can easily be damaged when digging for these clams.
Ecology[edit]
Ensis species live in clean sand on exposed beaches. They are capable of digging very rapidly; see the description under the Atlantic jackknife clam. Some clammers catch jackknives by pouring salt on the characteristic keyhole-shaped breathing holes. The clam then tries to escape the salt by coming up out of its hole, and at this point it is possible to gently grab the shell and pull it out of the ground.
Species[edit]
Thirteen species are currently recognised:[1]
- Ensis californicus (Dall, 1899)
- Ensis directus (Conrad, 1843) – Atlantic jackknife clam
- Ensis ensis (Linnaeus, 1758)
- Ensis goreensis (Clessin, 1888)
- Ensis macha (Molina, 1782)
- Ensis magnus (Schumacher, 1817)
- Ensis megistus (Pilsbry & McGinty, 1943)
- Ensis minor (Chenu, 1843)
- Ensis myrae (Berry, 1954)
- Ensis nitidus (Clessin, 1888)
- Ensis siliqua (Linnaeus, 1758) – pod razor
- Ensis terranovensis (Vierna & Martínez-Lage, 2012)
- Ensis tropicalis (Hertlein & Strong, 1955)

Mesheften (of scheermessen zoals vissers ze noemen) is de verzamelnaam voor verschillende soorten schelpdieren, waarvan het kleine en groot tafelmesheft, de grote zwaardschede, de Amerikaanse zwaardschede en de messchede de belangrijkste zijn. Op het strand kun je de amerikaanse zwaardschede het vaakst vinden. De grote Amerikaanse zwaardschede heeft maar 15 seconden nodig om zich helemaal in te graven! Er wordt geëxperimenteerd met visserij op deze soorten.

Razor shells (called jackknife or razor clam by the fishermen) is a collective term for various species of shellfish, the most important ones being the giant razor clam and the American, the pod, the grooved and the common razor shell. On the beach, you find the American razor clam the most often. This animal only needs 15 seconds to bury itself completely in the bottom! There are some fishermen experimenting with fishing razor shells commercially.
