Gemeine Schwertmuschel

<em>Ensis ensis</em>, the common razor clam, is a bivalve mollusk in the family Pharidae, order Adapedonta. It is distributed along the northeastern Atlantic coastline, with documented populations in Belgium, Denmark, Norway, and Sweden. The species is assessed as Least Concern by the IUCN, suggesting stable populations across much of its range. Common razor clams typically inhabit sandy intertidal and shallow subtidal zones, burrowing rapidly into sediment using their muscular foot to evade predators and avoid desiccation. Their elongated shell, resembling an old-fashioned straight razor, is a distinctive morphological feature of the genus Ensis. <em>Ensis ensis</em> is a suspension feeder, typically drawing in water and filtering phytoplankton and organic particles through its siphons. This feeding strategy makes it an important component of coastal benthic communities. Razor clams play an ecological role as both filter feeders improving water clarity and as prey items for shorebirds, flatfish, and marine mammals. Biological traits such as precise lifespan, body measurements, and diet composition vary across populations and remain incompletely characterized. The species is commercially harvested in parts of its range and is considered a minor fishery resource in Scandinavian waters.
