This family is best known for the shells of the species ''Placuna placenta'', which are translucent, and are commonly used in shellcraft production. In some cultures, they were used as a form of light-admitting window.〔("Fisheries and aquaculture of window-pane shells" ). Malacological Society of London. Retrieved on 2011-10-23.〕 The family is closely related to the Anomiidae (saddle oysters). One of the main differences is that the Placunidae do not attach themselves to a hard surface but are instead a mud-living family. ==Description== Placunidae are suspension feeders, living on shallow, muddy-bottomed waters. The usually lie with the right valve downwards. The ligament is internal and forms a shallow V-shape. 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「Placunidae」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
