This large species is characterized by rhomboid pectoral fin disc wider than long, a relatively long snout, and a short, blunt tail (though tail damage experienced by the original rays caught is a possibility). The International Union for Conservation of Nature (IUCN) has listed this species as Data Deficient and recommended further study. ==Taxonomy== Russian ichthyologist Georgii Ustinovich Lindberg published the description of the giant stumptail stingray in his and Soldatov's 1930 ''A Review of the Fishes of the Far-Eastern Seas''. Lindberg created the new genus ''Urolophoides'' for this species, in reference to its short tail which resembles that of stingrays in the genus ''Urolophus''. In 1990, Nishida and Nakaya placed ''Urolophoides'' in synonymy with ''Dasyatis''.〔Nishida, K. and K. Nakaya (1990). "Taxonomy of the genus ''Dasyatis'' (Elasmobranchii, Dasyatididae) from the North Pacific." in Pratt, H.L., S.H. Gruber and T. Taniuchi. ''Elasmobranchs as living resources: advances in the biology, ecology, systematics, and behaviour, and the status of fisheries.'' NOAA Technical Report, NMFS 90. pp. 327–346.〕 In 1999, Dolganov proposed that this species may be the same as the red stingray (''D. akajei'').〔 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「Giant stumptail stingray」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.
