Max length : 63.0 cm TL male/unsexed; (Ref. 5217); common length : 40.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 58.30 g (Ref. 118626)
Dorsal spines (total): 1. Three pairs of barbels on rostral region, two pairs on lower jaw, one pair on posterior end of maxilla; end of maxilla barbel reaching insertion of pectoral fin; body yellow-brown, whitish ventrally; each fin membrane blackish distally (Ref. 13608).
Found on muddy bottoms of shallow brackish waters; also in marine waters. Reproduction seems to occur between May and June. The female lays down 20-30 eggs having a diameter of 10-12 mm, agglutinated in mucus. The male guards the eggs for 10-12 days until hatching (Ref. 35381). Marketed fresh.
