Maturity: Lm ?, range 13 - ? cm
Max length : 70.0 cm TL male/unsexed; (Ref. 40637); common length : 25.0 cm TL male/unsexed; (Ref. 3265); max. published weight: 5.5 kg (Ref. 7251)
4 chin barbels and a longitudinal groove in a depression on midline of head.
Adults inhabit continental waters and enter estuaries. Found in turbid waters over muddy bottoms. Males incubate eggs in the mouth (Ref. 205). Commonly captured from catwalks, bridges and piers, particularly in passes and inland waterways. Edible, but generally not consumed (Ref. 7251).
Males carry the eggs in the mouth (Ref. 205).
