Some authorities classify this oyster as ''Pinctada imbricata fucata'' (Gould, 1850).〔 It is native to shallow waters in the Indo-Pacific region and is used in the culture of pearls. ==Description== ''Pinctada fucata'' has two valves connected by a long straight hinge. The length of the shell is slightly greater than its width, and the latter is about 85% of the length of the hinge. The right valve is flatter than the left and there are hinge teeth in both valves. The anterior ear is larger than that in other members of the genus and there is a slit-like notch for the byssus threads to pass through at the junction of the ear and the rest of the shell. The posterior ear is large. The outer surface of the valves is scaly and reddish or golden brown with pale radiating streaks. The inner surface of the valve is lined with a thick layer of golden-yellow nacre with a metallic sheen. 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「Pinctada fucata」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.
