Mya arenaria distribution

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 IN THE MYA ARENARIA SHELL FOR THE POSSIBLE DETERMINATION OF SUBSISTENCE PROCESSING HISTORY A Thesis. Presented to the. Faculty of California State University, San Bernardino by. Dane Robert Chance.

emerging reports of epizootic diseases in Mya arenaria, prompted a survey in summer 2000 of the health status of selected commercial clam populations. All sampled populations (8 M. arenaria softshell clam, 2 Tagelus plebeius razor clam) were infected by Perkinsus sp.

arenaria'' originated in the Pacific Ocean during the Miocene. It extended its range in the early Pliocene to the Atlantic, including European waters. The Pacific and European populations became extinct some time in the early Pleistocene, leaving only the Northwest Atlantic population, which subsequently spread via humans to its current distribution.

This species attains a maximum shell length of about 15 cm (10-11 in the Chesapeake Bay), with an oval, elongated shell ranging from white to dark grey in color. Little is known about the biology of the softshell clam in Europe, despite it being identified as a potential species to culture for food in the future. Monthly samples of the softshell clam, Mya arenaria, were collected intertidally from Co. Wexford, Ireland, over a period of sixteen months. Taxonomy: Mya arenaria is this species original name and is almost exclusively used currently.

It is the east coast of North America, but there is uncertainty about the northern as well as the southern limit. Most publications give a range from Labrador to North Carolina Abstract Patchy distribution is frequently observed in benthic marine invertebrates.
