成熟: Lm ?  range ? - ? cm
Max length : 130 cm SL オス/雌雄の選別がない; (Ref. 30857)
背面の脊椎 (合計) : 0; 背鰭 (合計) : 0; 臀鰭: 75 - 91. No dorsal fin; greatly reduced barbels (equal to or smaller than eye diameter); a slender body (Ref. 27732); body depth 5.7-7.0 times in SL; mandibular barbels smaller than eye diameter or absent (Ref. 43281). Vomerine teeth in angular band (Ref. 12693).
Body shape (shape guide): elongated.
Occurs in large rivers with turbid waters (Ref. 27732), streams, canals (Ref. 12693) and lakes (Ref. 56749). Feeds on pelagic fishes in midwater to upper depths (Ref. 12693). Spawns just prior to the rise in water levels and moves into the flooded riparian forests and probably out into the floodplains during high water levels. Young of the year are first seen in July and start to move back to the rivers in October, where they remain common until January (Ref. 12693).
