Southeast Asia: endemic to the Mekong River (Cambodia and Thailand); introduced to Chao Phraya River (Thailand).
Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 62.0 cm WD Männchen/unbestimmt; (Ref. 27732); max. veröff. Gewicht: 6.0 kg (Ref. 27732)
Rückenflossenstacheln (insgesamt) : 0; Afterflossenstacheln: 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.
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).
Lebenszyklus und Paarungsverhalten
Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fruchtbarkeit | Larven
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).
