背棘 (总数) : 0. A large, plain, dark stingray with an angular snout and pectoral disc; tail long and broad-based, less than twice body length, and with no upper caudal finfold but with high lower caudal finfold- 2 to 3 times depth of tail but not reaching tail tip; no large thorns; 1 or 2 long stings on tail, further behind tail base than in most stingrays; unique hexagonal, high-crowned teeth (Ref. 5578).

一个大的，单色的，和深色的 有一个有角的吻与胸盘; 尾部长而基底宽的, 小于两倍体长, 而且没有上尾部的鳍褶但是有高的下尾部的鳍褶- 2 到 3 倍高于尾部但是不达到尾部顶端; 没有大的刺; 在尾部上的 1 或 2 长的刺, 在尾部基底更后面超过在大部分的 中; 独特的六角形又高冠的齿.(参考文献 5578) 深褐色或黑色的背面没有显着的斑纹, 腹侧白色的.(参考文献 5578) 尾部黑色.(参考文献 3263)
Found in lagoons, reef flats, and reef faces (Ref. 12951). Also in rivers far from the sea (Ref. 5578). Feeds on bony fishes, worms, shrimp, and crabs (Ref. 12951). Ovoviviparous (Ref. 50449). Adults are sometimes accompanied by remoras or members of the trevally family (Ref. 6871). Size at birth about 18 cm WD or larger (Ref. 6871). Flesh utilized as food and skin used for polishing wood (Ref. 4832). Possibly caught by sports anglers (Ref. 5578). Recently there is a targeted fishery on this species for its skin, which is used as 'shagreen' in fashion accessories, from wallets to fancy pens; as a result, the species is in danger of disappearance (IHT 26.11.2005, p.5). Maximum length about 300 cm TL (Ref. 30573).

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). Size at birth ~ 18 cm WD (Ref.58048). 印度-西太平洋: 紅海, 波斯灣與南非至密克羅尼西亞,北至日本, 南至美拉尼西亞與阿拉弗拉海.(參考文獻 9819)
