Etymology: Cosmochilus: Greek, kosmos, -ou = order, organization + Greek, cheilos = lip (Ref. 45335). More on author: Sauvage.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; potamodromous (Ref. 51243); depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -
Asia: Chao Phraya and Mekong basins.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 12693); common length : 30.0 cm TL male/unsexed; (Ref. 12693)
Vertebrae: 35. With 5 branched anal fin rays; life color black rich pale blue, dorsal and caudal fins black-edged; in some specimens anal fin with black tip. Dorsal fin may also be black-tipped (Ref. 13216). Lips covered by large papillae; last simple dorsal ray osseous and serrated (Ref. 43281).
Occurs from midwater to bottom depths in the middle and lower Mekong. Inhabits clear waters of the main channels during the dry season and moves to floodplains and riparian forests during the rainy season. Relatively common in the upland river habitat of the middle Mekong until water levels begin to rise. Dietary habits still unknown, but the subterminal mouth and papillate lips indicate that it probably roots around for food in fine-grained sediments (Ref. 12693). Found in the basin-wide mainstream of the lower Mekong (Ref. 36667).
