Often very common in estuaries, where it may occur in extensive beds. Mya arenaria from the beach at Freeland, Holmes Harbor, Whidbey Island. (Photo by: Dave Cowles, July 2007) Description: As with other members of Family Myidae, this species has a shelflike or spoonlike chondrophore projecting from the hinge plate of the left valve , has two adductor muscles of similar size, and no radial ribs . M. arenaria är en av tre arter Sandmusslor som förekommer i Sverige och den vanligaste. Henrik Munthe namngav 1910 Myahavet efter denna musselart, efter den tid i slutet av järnåldern då han antog att arten invandrat till Östersjön i samband med minskad salthalt.

Juveniles of both Mya arenaria and the bivalve Scrobicularia plana were found to avoid excavated experimental plots, showing a significantly higher abundance in the control Distribution and habitat This species is widespread over the Arctic seas and extends to the Bay of Biscay, to the West Atlantic coast and to Sakhalin on the Pacific coast. It has been reported also in the waters around Japan. Mya arenaria seems to often die in situ, forming so-called death assemblages (Strasser, 1999), which can persist for maybe 100 years or more and form habitats for other species (Palacios et al ., 2000). Mya arenaria ; La cutícula exterior desaparece rápidamente tras la muerte de la almeja dejando al descubierto las estrías de crecimiento. La almeja de Nueva Inglaterra habita enterrada en el sedimento marino a unos 90 cm de profundidad, filtrando agua a través de un largo sifón. Mya truncata . CARATTERI DISTINTIVI Simile a M. truncata ma di taglia maggiore e più ovale.

It is often abundant in estuaries and on beaches. It may contract fully into the shell, but usually extends and stretch the siphon through the sand. Shells of the oyster (Crassostrea virginica), soft-shelled clam (Mya arenaria), and surf clam (Spisula solidissima), stacked randomly in tanks, have worked well and demonstrate principles that could be used to develop a commercial substrate. Each habitat configuration supports a different size range of lobsters.

Mya arenaria invaded new habitats by different modes: 1) natural range expansion 2) intentional as plantings 3) unintentional as a ballast species 4) unintentional as a byproduct of oyster transplants. Properties that may favor its wide range of distribution and invading success are: Description. Shells of Mya truncata can reach a size of about 2.5–7.5 centimetres (0.98–2.95 in). These bivalves are similar to the soft-shell clams (Mya arenaria), but usually they are smaller.Moreover, their shells are less elongated. Valves are rounded in the anterior end and truncated in the posterior end, with a large gape allowing the passage of an extensible siphon that can reach ABSTRACT Soft-shell clams, Mya arenaria , and razor clams, Tagelus plebeius , in Chesapeake Bay have declined since the 1970s, with severe declines since the 1990s. These declines are likely caused by multiple factors including warming, predation, habitat loss, … NOBANIS (undated) reports that Mya arenaria competes with other species, causes abiotic changes, and uses resources. Other ecological impacts of M. arenaria include benthic-pelagic interaction, bioaccumulation, community dominance, and habitat change.

The subgenera of Mya (Mya mya, Mya arenomya) Impacts of Mya arenaria range from habitat alteration to massive bioaccumulation.
