The Estuary Cod is brown above and whitish below. It has five irregular, oblique bars on the body that bifurcate ventrally. There are numerous small orange-brown spots on the head, body and median fins. The spots are pupil-sized in small fish (see middle image) but become relatively smaller and more numerous as the fish ages.
Young fish are usually found in estuaries and silty areas although have also been reported from freshwaters. Adults are often found in marine offshore areas at depths around 100 m.
