Épines dorsales (Total) : 1. The head is flattened on top. The snout is short and large and transversally truncated. Mouth terminal, the lower jaw is the same length or slightly longer than the superior jaw. It has three pairs of barbels (1 pair maxillary barbels, 2 pairs of mandibular barbels) (Ref. 35381).
Body shape (shape guide): elongated.
Occurs in coastal waters and river estuaries. Found on shallow muddy bottoms (Ref. 5217). Reproduction seems to occur twice a year, in April and in October. The female lays 20-25 eggs measuring 12-15 mm. Mouth-brooding by the males lasts 10-12 days (Ref. 35381). Marketed fresh and salted (Ref. 5217).
