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). The subgenera of Mya (Mya mya, Mya arenomya) Impacts of Mya arenaria range from habitat alteration to massive bioaccumulation. 物种描述 Mya arenaria can grow to be 10-15cm long and 8-19cm wide with a white to pale grey shell which can be variable in colour depending on the sediment stratum it burrows into. Mya arenaria is located in the taxonomic order Myoida, which lacks any member with a completely annotated mitogenome.

are distributed from the sub arctic regions to as far south as North Carolina (Abraham and Dillon, 1986; Maximovich and Guerassimova, 2003).

IN CHESAPEAKE BAY Patrick Baker and Roger Mann Special Scientific Report No. 125 Virginia Institute of Marine Science School of Marine Science The College of William and Mary Gloucester Point, VA 23062 December 1990 Supported in part by the U.S. Fish and Wildlife Service As we observed the smallest recruited juveniles of Mya arenaria (2 mm) throughout the study period, we concluded that the clam is capable of reproducing in the new habitat. 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).

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. However, it died out on the east coasts of the Pacific and the Atlantic during glaciation of the Pleistocene. M. arenaria and T. plebeius were found more often in habitats with complex physical structures (seagrass, shell) than any other habitat.
