Mya arenaria Softshell clam. Species Description. The softshell clam is a marine/estuarine bivalve species of the Family Myidae. 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.

Twenty-five populations of Mya arenaria were sampled along the northeast coast of North America, from Chesapeake Bay to Nova Scotia. Significant correlations were found among life-history parameters, and these varied systematically with latitude.
