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).

Earlier studies demonstrated that densities of 0-y-old individuals of Mya arenaria L. were lower in Washington County on the eastern Maine coast than in Cumberland County on the southern Maine coast.

Henrik Munthe namngav 1910 Myahavet efter denna musselart Newell and Hidu, 1986). The juvenile spat is generally attached to the substrate, but can crawl to a more favorable location with the foot (Abraham and Dillon, 1986). The floating and crawling stage can last 2-5 weeks, but the spat eventually burrow into the sediment, becoming sedentary (Abraham and Dillon, 1986; Newell and Hidu, 1986). The observed regional differences in juvenile and adult M. arenaria could result from a lack of competent larvae over eastern versus southern Maine tidal flats in the form of either local effects (e.g., postponing metamorphosis to avoid settling on flats characterized by pollution, contamination, or otherwise unattractive habitat qualities until they are carried elsewhere) or regional effects associated with fewer M. arenaria larvae in the water column throughout eastern Maine.We tested 2012-05-05 · Juvenile Mya clams in the lab.
