Not evaluated (IUCN 3.1)
Oxyeleotris lineolata, the Sleepy cod, is a medium-sized sleeper goby, native to tropical fresh waters of northern Australia and questionably from New Guinea. This species can reach a length of 45 centimetres (18 in) SL though most do not exceed 20 centimetres (7.9 in) SL. The Sleepy cod is a member of the order Perciformes, and thus unrelated to the true cods in the order Gadiformes. Nor are they closely related to the Australian freshwater cods such as the Murray cod of the family Maccullochella.
Sleepy cod generally weigh up to 3 kilograms (6.6 lb). They are very common in waterways across northern Australia. They are plain brown coloured fishes. They are sedentary in nature. They are one of the most favoured freshwater fish in Australia for eating, having white, flaky flesh, low fat content and a mild flavour.
