Its scientific name is ''Lampetra fluviatilis''. ==Description== Adult river lampreys measure from for the sea-going forms and up to for the lake forms. The very elongate body is a uniform dark grey above, lightening to yellowish off-white on the sides and pure white below. Like all lampreys these fish lack paired fins and possess a circular sucking disc instead of jaws. They have a single nostril and seven small breathing holes on either side behind the eye. The teeth are sharp and these fish can be told from the rather smaller brook lamprey (''Lampetra planeri'') by the fact that the two dorsal fins are more widely separated.〔(【引用サイトリンク】title=River lamprey: ''Lampetra fluviatilis'' )〕 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「European river lamprey」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.
