The Atlantic surf clam, also referred to as the "bar clam," "hen clam," "skimmer," or simply as the "sea clam," is a western Atlantic surf clam, a very large (20 cm), edible, saltwater clam or marine bivalve mollusk in the family Mactridae. It is a much larger relative of the eastern Atlantic surf clam. The shell of this species is a well-known object to beach-goers in the northeastern United States. People on the beach often pick up a large empty shell of this species, either to dig in the sand with, or take home to use as a decorative dish or ashtray. The species is exploited commercially as a food item. ==Distribution== This common species occurs off the east coast of North America from Nova Scotia to South Carolina. It has also been introduced and farmed in Hokkaidō, northern Japan. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Atlantic surf clam」の詳細全文を読む スポンサード リンク
