Southeast Asia: endemic to the Mekong River (Cambodia and Thailand); introduced to Chao Phraya River (Thailand).
亞洲: 湄南河與湄公河流域。 可能地在婆羅洲。

成熟度: Lm ? range ? - ? cm
Max length : 62.0 cm WD 雄魚/尚未辨別雌雄; (Ref. 27732); 最大體重: 6.0 kg (Ref. 27732)
背棘 (總數) : 0; 臀棘: 0. Distinguished from the other stingray species in the Mekong basin by the presence of a ventral and a dorsal skin folds on the tail and the bright orange color of the ventral surface of the disc. The middle disc is whitish with scattered large orange spots. The dorsal surface of the disc is brown (Ref. 27732). Disc longer than wide; tail longer than body (Ref. 12693). Lacking caudal fin; with long whip-like tail (Ref. 43281).
Body shape (shape guide): other.
在湄公河流域中與另一個魟種區分藉由有一個尾部腹面與背面的皮褶與體盤上鮮橘色的腹鰭。 中央的體盤是微白色的具有分散的大橘色的斑點。 體盤的背部表面是褐色。 (參考文獻 27732) 體盤長度超過寬的; 尾部較長超過身體.(參考文獻 12693) 缺乏尾鰭; 有長的鞭狀尾部。 (參考文獻 43281)
Obligate freshwater stingray that occurs over sandy substrate in large rivers. Feeds on bottom-dwelling invertebrates (Ref. 12693). Ovoviviparous (Ref. 50449). Marketed fresh (Ref. 32457).

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).亞洲: 湄南河與湄公河流域。 可能地在婆羅洲。
