Editing Eastern freshwater cod (section)

==Appearance and size==
The eastern freshwater cod is a small to medium-sized grouper-like fish with a deep, elongated body that is round in cross section and a broad, scooped head, and a large mouth lined with pads of very small needle-like teeth. The jaws are equal, or the lower jaw may protrude slightly. The eyes are slightly larger and more prominent than in Murray cod.

The spiny dorsal fin is moderate in height and is partially separated by a notch from the high, rounded soft dorsal fin. Soft dorsal, anal, and caudal (tail) fins are all large and rounded, and are dusky grey or black with distinct white edges. The large, rounded pectoral fins are usually similar in colour to flanks. The pelvic fins are large and angular, set forward of the pectoral fins, and are usually a translucent greyish-white colour, tending toward opacity in large fish. The leading greyish-white coloured rays on the pelvic fins split into two trailing filaments. These filaments are significantly longer than in Murray cod.

Eastern freshwater cod are vary from cream or greyish-white to yellow on their ventral (“belly”) surfaces. Their backs and flanks are usually an intense yellow or gold in colour, overlain with a dense pattern of black to very dark green mottling. The effect is a marbled appearance sometimes reminiscent of a leopard's markings. Colouration does vary considerably however and eastern freshwater cod from dark, heavily shaded habitats can be very dark or almost black in colour.

Eastern freshwater cod were historically recorded reaching sizes well over 1&nbsp;metre in length and up to 48&nbsp;kg in weight, but today are commonly less than 60&nbsp;cm in length and less than 5&nbsp;kg in weight. Large fish are rare today.<ref name=rowland_1993/>
