Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 50.0 cm TL mâle / non sexé; (Ref. 3265); common length : 30.0 cm TL mâle / non sexé; (Ref. 3265); poids max. publié: 33.30 g (Ref. 118626)
Épines dorsales (Total) : 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).
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).
