背面の脊椎 (合計) : 11 - 14; 肛門の骨: 0; 臀鰭: 9 - 18; 脊つい: 53 - 57. Diagnosis: lower jaw longer than upper jaw; pectoral fin reaching first dorsal ray (Ref. 2835, 42908, 81263). 11-14 dorsal finlets (Ref. 28714, 122071), the first situated above the pectoral fins; head flat or slightly concave between the eyes but not convex (Ref. 28714). Third dorsal scale row the first to reach ventral midline; predorsal length short, 21.7-27.4 % SL; few (4-5, rarely 6), broad (more than 3 scale rows wide), dark transverse bars extending from dorsum to middle of flank by confluence of dorsal and lateral blotches sometimes including ventrolateral markings (Ref. 122071).
Body shape (shape guide): elongated; Cross section: compressed.
Facultative air-breathing (Ref. 126274); Inhabits swamps and rivers. Essentially piscivorous (Ref. 9695, 28714). Diet includes snails and crustaceans (Ref. 30488).
