Answer 1

The Murray cod (Maccullochella peelii peelii) is a large Australian predatory freshwater fish of the Maccullochella genus and the Percichthyidae family. Though the fish is called cod in the vernacular, it is no way related to the Gadus genus of fish. It is an important and charismatic part of Australia's vertebrate wildlife and is found in the Murray-Darling river system in Australia. The Murray cod is the largest exclusively freshwater fish in Australia, and one of the largest in the world. Other common names for Murray cod include cod, greenfish and goodoo.

The scientific name of Murray cod derives from an early Australian fish researcher with the surname McCulloch and the river from which the explorer Major Mitchell first scientifically described the species, the Peel River. This was later changed to M. peelii peelii to differentiate Murray cod from Mary River cod, which are currently designated as a subspecies of Murray cod.

Murray cod populations have declined severely since European colonisation of Australia due to a large variety of factors including overfishing and are now a listed threatened species. However, they once inhabited almost the entire Murray-Darling Basin, Australia's largest river system, in very great numbers.

A long lived fish, adult Murray cod are carnivorous and mainly eat other fish. The species exhibits a high degree of parental care for their eggs, which are spawned in the spring and are generally laid in hollow logs or on other hard surfaces. Murray cod are a popular angling target and aquaculture species. Often available through the aquarium trade, they are also a popular aquarium species in Australia.

Murray cod are a large grouper-like fish with deep, elongated bodies[1] that are round in cross section. They have a broad, scooped head, and a large mouth lined with pads of very small needle-like teeth. The jaws of the Murray cod are equal, or the lower jaw protrudes slightly.[2][3][4]

The spiny dorsal fin of Murray cod is moderate to low in height and is partially separated by a notch from the high, rounded soft dorsal fin.[3] Soft dorsal, anal and caudal (tail) fins are all large and rounded, and are dusky grey or black with distinct white edges.[1][4] The large, rounded pectoral fins are usually similar in colour to the flanks. The pelvic fins are large and angular and set forward of the pectoral fins. The leading white-coloured rays on the pelvic fins split into two trailing white filaments,[3] while the pelvic fins themselves are usually a translucent white or cream, tending toward opacity in large fish.

Murray cod are white to cream on their ventral (belly) surface.[3][4] Their back and flanks are usually yellowish-green to green, overlain with heavy darker green, but occasionally brown or black, mottling.[2][3][4] The effect is a marbled appearance sometimes reminiscent of a leopard's markings. Colouration is related to water clarity;[4] colouration is intense in fish from clear water habitats. Small to medium sized Murray cod from clear water habitats often have striking and very distinct colouration. Very large fish tend towards a speckled grey-green colouration.
