''Busycon'' is a genus of very large edible sea snails, marine gastropod mollusks in the family Buccinidae. These snails are commonly known in the United States as ''whelks'' or ''Busycon whelks''. Less commonly they are loosely, and somewhat misleadingly, called "conchs". ''Busycon'' comes from the Greek ''bousykon'' meaning ''large fig'', from ''bous'' meaning ''cow'' and ''sykon'' meaning ''fig''.〔(''busycon'' in Meriam-Webster Unabridged )〕 ==Shell description== Shells of species in this genus can grow to a length of 40 cm. They all have a long siphonal canal. The shells are generally a solid cream, light grey or tan in color, however the shell of ''Busycon perversum'' is marked with brown and white streaks. The shell of individuals can sometimes vary quite widely in coloration and sculpture. The lightning whelk, native to the Gulf of Mexico, is unusual among gastropods, having a sinistral shell. 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「Busycon」の詳細全文を読む スポンサード リンク
