Herring are various species of forage fish, belonging to the order Clupeiformes.
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.
Dascyllus is a genus of fish in the family Pomacentridae. They are usually commensals with corals.
Amphilophus is a genus of cichlid fishes from Central America, ranging from southern Mexico to Panama. The genus currently contains 23 species, including several that are well known from the aquarium trade. However, studies led by Oldřich Říčan in 2008 and 2016 suggested that several species within Amphilophus should be moved to the genus Astatheros. Species proposed to be moved to Astatheros in 2008 were A. alfari, A. altifrons, A. bussingi, A. diquis, A. longimanus, A. macracanthus, A. margaritifer, A. rhytisma, A. robertsoni and A. rostratus. Further genetic studies led Říčan to put A. macracanthus in Astatheros, but to put A. alfari, A. altifrons, A. bussingi, A. diquis, A. longimanus, A. rhytisma, A. robertsoni and A. rostratus within the genus Cribroheros. Říčan's study suggests that the Astatheros species are more closely related to the Jack Dempsey and rainbow cichlid than to the remaining Amphilophus species.
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.
The threespot dascyllus, also known as the domino damsel or simply domino, is a species of damselfish from the family Pomacentridae. It is native to the Indo-Pacific from the Red Sea and East Africa, to the Pitcairn Islands, southern Japan, and Australia, and can also be found in some parts of the Philippines.
Verduya's hap is a species of haplochromine cichlid which is endemic to Lake Malawi. It has a lake-wide range and is thus found in Malawi, Mozambique, and Tanzania. This species occurs in open water, sometimes forming large shoals.
Adamson's grunter is a species of freshwater ray-finned fish, a grunter from the family Terapontidae which is endemic to Lake Kutubu in the Kikori River system, Papua New Guinea.
The long-nose sooty grunter is a species of fish in the family Terapontidae. It is endemic to Australia.
The striped grunter is a species of freshwater ray-finned fish, a grunter from the family Terapontidae. It is found only in the Bewani Mountains in the headwaters of the Pual River system in Papua New Guinea and the upper Sermowai River, Western new Guinea, Indonesia.
The flat-faced seahorse, longnose seahorse, low-crowned seahorse or three-spot seahorse is a species of fish in the family Syngnathidae. It is found in Australia, Cocos (Keeling) Islands, French Polynesia, Hong Kong, India, Indonesia, Japan, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. Its natural habitat is shallow seas. It is threatened by habitat loss.
Apolemichthys xanthurus, the Indian yellowtail angelfish, is a species of marine angelfish belonging to the family Pomacanthidae. Other common names include cream angelfish, smoke angelfish, and yellowtail black angelfish. It is found in the Indian Ocean.
Threespot barb is a species of cyprinid fish in the large genus Enteromius. It has a wide distribution in sub-Saharan Africa from the Congo Basin east to the Indian Ocean coast of Tanzania and south to KwaZulu Natal in South Africa. It occurs in shallow water around river inflows or near swampy areas. It is a habitat generalist and also hardy, but it prefers vegetated areas. It feeds on insects and other small animals. It is often caught for use as bait by anglers fishing for tigerfish. It breeds during the summer rainy season when shoals of fertile adults migrate upstream when the rivers are in spate following rain. A single females may produce as many as 8,000 eggs.
The sooty grunter, also known by the name black bream, blubberlips, Northern grunter or purple grunter, is a species of freshwater ray-finned fish, a grunter from the family Terapontidae. It inhabits coastal and inland freshwater creeks and rivers of northern Australia.
Bathycongrus trimaculatus is an eel in the family Congridae. It was described by Emma Stanislavovna Karmovskaya and David G. Smith in 2008. It is a tropical, marine eel which is known from the southwestern Pacific Ocean, including Fiji, New Caledonia, and the Solomon Islands. It dwells at a depth range of 357–550 metres. Males can reach a maximum total length of 16.1 centimetres.
Apolemichthys trimaculatus, the threespot angelfish or flagfin angelfish, is a demersal marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It has a wide Indo-Pacific distribution.
Hephaestus carbo, the coal grunter or black grunter, is a species of freshwater ray-finned fish, a grunter from the family Terapontidae. It is endemic to rivers in northern Australia.
Hippocampus dahli is a fish species of the family Syngnathidae. It is endemic to the Australian northeastern coast, from Darwin to Brisbane, where it inhabits estuarine channels and rubble or soft substrates to depths of 21 metres (69 ft). Little is known of its feeding habits, but it is likely to feed on small crustaceans such as copepods, amphipods, and gammarid, caprellid, and caridean shrimps, similar to other seahorses. This species is ovoviviparous, with males carrying eggs in a brood pouch before giving birth to live young. This species is not listed in FishBase and many authorities treat it as a synonym of Hippocampus trimaculatus.
Hephaestus is a genus of freshwater ray-finned fish, grunters from the family Terapontidae.
Leporinus trimaculatus is a species of anostomid fish. It is found in the Aripuanã River basin in Brazil.
