The Bloomfield River cod or the tropical nightfish, is a species of temperate perch endemic to Australia. It is only found in an 11-km stretch of the Bloomfield River in northern Queensland. These waterfalls appear to have blocked the migration of more aggressive tropical freshwater fish species such as the sooty grunter that have presumably naturally displaced the Bloomfield River cod from its former range in prehistoric times. With its very limited distribution, the Bloomfield River cod is clearly a relict species. It is a very important relict species, however, as it is the most northerly distributed percichthyid species in Australia and raises interesting questions on the biogeography of percichthyid fish in Australia and the history of their ancient colonisation of Australian rivers.

The fauna of New Guinea comprises a large number of species of mammals, reptiles, birds, fish, invertebrates and amphibians.
The New Guinea crocodile is a small species of crocodile found on the island of New Guinea north of the mountain ridge that runs along the centre of the island. The population found south of the mountain ridge, formerly considered a genetically distinct population, is now considered a distinct species, Hall's New Guinea crocodile. In the past it included the Philippine crocodile, C. n. mindorensis, as a subspecies, but today they are regarded as separate species. The habitat of the New Guinea crocodile is mostly freshwater swamps and lakes. It is most active at night when it feeds on fish and a range of other small animals. A female crocodile lays a clutch of eggs in a nest composed of vegetation and she lies up nearby to guard the nest. There is some degree of parental care for newly hatched juveniles. This crocodile was over-hunted for its valuable skin in the mid 20th century, but conservation measures have since been put in place, it is reared in ranches and the International Union for Conservation of Nature (IUCN) lists it as being of "Least Concern".
Lake Kutubu is the second-largest lake in Papua New Guinea, after Lake Murray, and, at 800 m above sea level, the largest upland body of water, with an area of 49.24 km², and a total catchment area of 250 km². Lake Kutubu and Lake Sentani form an ecoregion on the WWF's Global 200. Kutubu lies in the Southern Highlands Province of Papua New Guinea, east of the Kikori River into which it drains, and about 50 km southwest of Mendi, the provincial capital. It is one of the few lakes in the country that occurs in a depression in the rugged interior mountains. The lake has a few islands, the largest of which is Wasemi in its northern part. The water of Lake Kutubu, fed by several streams originating mostly from underground sources, is clear and reaches a depth of 70 m (230 feet). The catchment is inhabited by two main ethnic groups, the Foe to the south and the Fasu to the north. Thirty-three villages lie in the catchment area, with a total estimated population of 10,885.
