Mya arenaria has a calcium carbonate shell, which is very thin and easily broken, hence the name "soft-shells" (as opposed to its beach-dwelling neighbors, the thick-shelled quahog). This clam is found living approximately 3–8 in (7.6–20.3 cm) under the surface of the mud.

Mya arenaria lives in burrows up to 50 cm deep in sand, mud, sandy mud, and sandy gravels from the mid shore to the shallow sublittoral, sometimes to a depth of 192 m. Often abundant on estuarine flats where it can survive at salinities as low as 4-5 psu. Mya arenaria has a calcium carbonate shell, which is very thin and easily broken, hence the name "soft-shells" (as opposed to its beach-dwelling neighbors, the thick-shelled quahog). This clam is found living approximately 3–8 in (7.6–20.3 cm) under the surface of the mud. habitat : muddy, sandy and gravelly bottoms, intertidal from the shore and estuaries mainly in shallow water down to 75 m.

Mercenaria mercenaria are found in the intertidal zone from the Gulf of killed off the entire soft-shelled clam, Mya arenaria, population (Mitchell 2001). oysters Crassostrea virginica, soft shell clams Mya arenaria, hard shell clams This viewpoint is largely absent from current bay scallop habitat discussions. Mya arenaria, was only abundant inside cages.

Habitat Requirements for the Softshell Clam, Mya arenaria in the Chesapeake Bay @inproceedings{Baker1990HabitatRF, title={Habitat Requirements for the Softshell Clam, Mya arenaria in the Chesapeake Bay}, author={P. Baker and R. Mann}, year={1990} } Taxonomy: Mya arenaria is this species original name and is almost exclusively used currently. However, the taxonomic history of this species includes many synonyms, overlapping descriptions, and/or subspecies (e.g. Mya hemphilli, Mya arenomya arenaria, Winckworth 1930; Bernard 1979).

Linear growth of soft-shell clams, Mya arenaria L., was studied at six locations in the White Sea situated in the middle and low tidal zones. The main aim was to analyse the growth heterogeneity both within beds (with respect to individual growth) and between beds (with respect to group growth). Mya population was characterized by a slow growth and a long lifespan. Maximum shell size was 70

Mya arenaria currently occupies a wide geographical range in the northern hemisphere, on both coasts of the Atlantic as well as on the Pacific east coast. Some authors claim it also occurs on the Pacific west coast. The species originated in the Pacific during the Miocene and was already present on both Atlantic coasts in the Pliocene. M. arenaria and T. plebeius were found more often in habitats with complex physical structures (seagrass, shell) than any other habitat. Pulses in bivalve density associated with recruitment were attenuated through the summer and fall when predators are most active, indicating that predators likely influence temporal dynamics in these species. potentially affect food resources and habitat of commercially important bivalves like quahogs, Mercenaria mercenaria, and softshell clams, Mya arenaria. To define how land-derived nitrogen loads and resulting eutrophication affect bivalves, we compared estuarine features to growth and survival of clams across estuaries receiving different N loads.
