Premnas biaculeatus, commonly known as spine-cheeked anemonefish or the maroon clownfish, is a species of anemonefish found in the Indo-Pacific from western Indonesia to Taiwan and the Great Barrier Reef. They can grow up to be about 17 cm (6.7 in). Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict size-based dominance hierarchy; the female is largest, the breeding male is second largest, and the male nonbreeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male changes to female if the sole breeding female dies, with the largest nonbreeder becoming the breeding male. The fish's natural diet includes algae and zooplankton.
The Papuan epaulette shark, Hemiscyllium hallstromi, is a bamboo shark in the family Hemiscylliidae found around southern Papua New Guinea, between latitudes 7° S and 10° S, and longitude 144° E and 146° E. Its length is up to 75 cm.
The northern river shark or New Guinea river shark is a species of requiem shark, in the family Carcharhinidae, found in scattered tidal rivers and associated coastal waters in northern Australia and in Papua New Guinea. This species inhabits areas with poor visibility, soft bottoms, and large tides, with immature sharks ranging into fresh and brackish water. It is similar to other river sharks in having a stocky grey body with a high back, tiny eyes, and broad fins. It measures up to 2.5 m (8.2 ft) long.
Cichla ocellaris, sometimes known as the butterfly peacock bass, is a very large species of cichlid from South America, and a prized game fish. It reaches 74 cm (29 in) in length. It is native to the Marowijne and Essequibo drainages in the Guianas, and the Branco River in Brazil. It has also been introduced to regions outside its natural range, but some uncertainty exists over the exact identity, and at least some of the introductions may involve another Cichla species or hybrids. It is frequently confused with C. monoculus. Studies conclude that the introduction of Cichla ocellaris does not negatively impact fish communities in Florida, making it an effective fisheries management tool.
Kailola's hardyhead is a species of fish in the family Atherinidae endemic to Papua New Guinea. It reaches a maximum length of 6 cm. It inhabits shallow, clear creeks with gravel substrate. This species was described by Walter Ivantsoff, Lucy Crowley and Gerald R. Allen in 1987 with a type locality of a still backwater of Foasi Creek 3 kilometers west of Safia airstrip in Papua New Guinea. The specific name honours the Patricia J. Kailola, for her contribution to the knowledge of the ichthyology of Papua New Guinea.
Sicyopterus lagocephalus, the red-tailed goby or blue stream goby, is a species of goby native to islands of the Indian Ocean from the Comoros to the Mascarene Islands to the Pacific Ocean where it reaches French Polynesia and can be found as far north as Japan. It is an amphidromous species: adults can be found in swift-flowing streams with rocky beds but the eggs hatch at sea and the larval stage remains in marine waters, migrating to freshwaters when they reach the postlarval stage. This species can reach a total length of 13 cm (5 in). In some places it is an important species for local consumption with the post-larvae being caught as they mass in estuaries.
The freshwater anchovy or New Guinea thryssa is a species of ray-finned fish in the family Engraulidae. It is native to Australia, Indonesia and Papua New Guinea.
The Solomon Islands (archipelago) is an island group in the western South Pacific Ocean, north-east of Australia. The archipelago is in the Melanesian subregion and bioregion of Oceania and forms the eastern boundary of the Solomon Sea. The many islands of the archipelago are distributed across the sovereign states of Papua New Guinea and Solomon Islands. The largest island in the archipelago is Bougainville Island, which is a part of the Autonomous Region of Bougainville along with Buka Island, the Nukumanu Islands, and a number of smaller nearby islands. Much of the remainder falls within the territory of Solomon Islands and include the atolls of Ontong Java, Sikaiana, the raised coral atolls of Bellona and Rennell, and the volcanic islands of Choiseul, Guadalcanal, Makira, Malaita, New Georgia, the Nggelas, Santa Isabel, and the Shortlands. The Santa Cruz Islands are not a part of the archipelago.
The Papuan seerfish also called the Papuan Spanish mackerel, is a species of fish in the family Scombridae. It is endemic to the Gulf of Papua off the mouth of the Fly River. It is the smallest species in the genus Scomberomorus. Sexual maturity is attained at much less than 30 cm fork length.
Hemiscyllium galei, the Cenderawasih epaulette shark, is a species of bamboo shark in the family Hemiscylliidae. Together with H. henryi, it was only scientifically described in 2008 by Gerald R. Allen and Mark V. Erdmann. At present, H. galei is only known from depths of 2 to 4 metres at reefs in the Cenderawasih Bay in West Papua, Indonesia. The largest known specimen was 56.8 centimetres (22.4 in) long. It can be separated from its relatives by the combination of seven relatively large dark spots along the side of the body, white markings on the edge of its dark dorsal saddles and other scattered white spots on the upper side.
Papuengraulis is a monospecific genus of ray-finned fish belonging to the family Engraulidae, the anchovies. The only species in the genus is Papuengraulis micropinna, the littlefin anchovy, bareback anchovy or little anchovy. This species is fround from the Gulf of Papua in Papua New Guinea and in Northern Territory, Australia from the Keep River estuary to the East Alligator River.
Denariusa australis, known commonly as the pennyfish, is a species of ray-finned fish in the family Ambassidae, the Asiatic glassfishes. It is the only member of the monotypic genus Denariusa. It is native to Papua New Guinea and Australia. This species grows to a length of 4.5 centimetres (1.8 in) SL.
