背面の脊椎 (合計) : 1. Three pair of barbels on rostral region, two pairs on lower jaw, one pair on posterior end of maxilla; end of maxilla barbel reaching pectoral fin insertion; large saddle-shaped bony plate with rugosa surface in front of dorsal fin, anterior margin of this plate waved but no deep medial incision; body yellow or gray-yellow dorsally, white ventrally (Ref. 13608).
Body shape (shape guide): elongated.
Found in turbid waters over muddy bottoms in shallow coastal areas, also around estuaries (Ref. 3265), and coastal rivers (Ref. 39852). Food items include bottom-living invertebrates. Marketed fresh. Exported frozen (Ref. 5217). Reproduction period is probably between September and November. Egg diameter is 9-11 mm. Males practice mouth brooding of the eggs. (Ref. 35381).
