deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Absence of scalelike scutes on belly; bases of outer barbels usually behind bases of inner barbels (Ref. 86798).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Adults inhabit large, deep, turbid river channels, usually in strong current over firm sand or gravel (Ref. 10294, 58490). They feed on aquatic insect immatures, particularly caddisfly larvae, and small fish (Ref. 10294). Threatened due to over harvesting and habitat loss (Ref. 58490). No length type given but assumed to be in TL.
