This bottom-dwelling ray is most commonly found over sandy areas shallower than , as well as in estuaries. Measuring up to across, the pale-edged stingray has a diamond-shaped pectoral fin disc, a long projecting snout, small eyes, and a whip-like tail with both dorsal and ventral fin folds. It is chocolate brown above and white below. The diet of the pale-edged stingray consists mainly of small crustaceans and fishes. Reproduction is aplacental viviparous, with females bearing litters of 1–3 young. Caught as bycatch and utilized for its meat, this species is threatened by heavy fishing pressure throughout its range and has been assessed as Near Threatened by the International Union for Conservation of Nature (IUCN). ==Taxonomy and phylogeny== German biologists Johannes Müller and Friedrich Henle originally described the pale-edged stingray from seven syntypes, in their 1841 ''Systematische Beschreibung der Plagiostomen''. They named it ''Trygon zugei'' after ''zugu-ei'', the Japanese name for this species. The genus ''Trygon'' was synonymized with ''Dasyatis'' by subsequent authors. Several early accounts of ''D. zugei'' were confounded by specimens of ''D. acutirostra''; in 1988 Nishida and Nakaya published a study that resolved the differences between these two species and designated a new lectotype for ''D. zugei''. Lisa Rosenberger's 2001 phylogenetic analysis, based on morphological characters, found that the pale-edged stingray is sister to a clade containing the whitespotted whipray (''Himantura gerrardi''), the pearl stingray (''D. margaritella''), and the smooth butterfly ray (''Gymnura micrura''). These results support the growing consensus that neither ''Dasyatis'' nor ''Himantura'' are monophyletic. 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「Pale-edged 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.
