This oyster can be found in shallow water along the tropical and subtropical Pacific coast of America, its range including Baja California, Mexico and northern Peru. ==History== Fragments of shell ornaments made from the nacre of the Pacific wing-oyster have been found at ancient burial sites in Mexico, probably belonging to the indigenous Seri people of the Sonora region.〔 This oyster has been the subject of a pearl fishery in the Gulf of California since before the arrival of Fernando Cortez in 1535; the Spaniards quickly appreciated the value of the harvest and in 1586 they declared the gathering of oysters to be a right of the Spanish crown.〔 In 1874, compressed air diving equipment made harvesting the oysters easier.〔 Over-exploitation caused populations of the oyster to become depleted and in 1940 the fishery was closed by the Mexican Government, a ban that still remains in force. 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「Pteria sterna」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.
