The thorntooth grenadier or javelin fish, Lepidorhynchus denticulatus, is a rattail, the only member of the genus Lepidorhynchus, found around southern Australia and New Zealand, at depths of between 200 and 1,000 m. Its length is between 20 and 55 cm.
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia, and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 26 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth, and Adelaide.
New Zealand is a sovereign island country in the southwestern Pacific Ocean. The country has two main landmasses—the North Island, and the South Island —and around 600 smaller islands. It has a total land area of 268,000 square kilometres (103,500 sq mi). New Zealand is about 2,000 kilometres (1,200 mi) east of Australia across the Tasman Sea and 1,000 kilometres (600 mi) south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal, and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.
The sharpnose sevengill shark, also known as one-finned shark, perlon shark, sevengill cow shark, sharpsnouted sevengill or slender sevengill, is a species of shark in the family Hexanchidae, and the only living species in the genus Heptranchias. Found almost circumglobally in deep water, it is one of the few species of sharks with seven pairs of gill slits as opposed to the usual five. The other shark species with seven gill slits is the broadnose sevengill shark. Though small, this shark is an active, voracious predator of invertebrates and fish. When caught, this species is notably aggressive and will attempt to bite. It is of minor commercial importance.
The yellow-and-black triplefin, Forsterygion flavonigrum, a triplefin of the genus Forsterygion, is found around the north of the North Island of New Zealand at depths of between 15 and 30 m, in reef areas of broken rock. Its length is between 4 and 7 cm.
The New Zealand black angelfish or the black scalyfin, Parma alboscapularis, is a damselfish of the family Pomacentridae, found around northeastern New Zealand to depths of a few metres, over shallow rocky reef areas. Its length is between 24 and 28 cm.
The porae or blue morwong, Nemadactylus douglasii, is a morwong of the genus Nemadactylus, found around south eastern Australia and the north eastern coast of the North Island of New Zealand at depths of about 10 to 100 metres, on sandy and rocky coasts. Its length is between 40 and 100 cm. Max weight is at least 12 kg
The New Zealand demoiselle, Chromis dispilus, is a damselfish of the genus Chromis, found between North Cape and East Cape of the North Island of New Zealand to depths of about 60 metres, off rocky coasts. Its length is between 15 and 20 cm. Males are highly territorial as they defend their nesting area from other males and other species. These aggressive fish defend their eggs laid by their female counterpart. Spawning occurs between the months of December and March. The New Zealand demoiselle's territory and nesting grounds of this fish are usually the largest in a medium population density. Like most territorial fish they tend to spawn more in higher densities of the same species compared to lower densities. Aggression levels tend to be higher amount higher densities of the same species and lower levels in smaller densities. Aggression also tends to be higher during spawning then during egg defending. Elevated plasma levels of androgen testosterone and 11-Ketotesterone are associated with the heighten levels of aggression shown by the males.
Nemadactylus macropterus, commonly known as the tarakihi or jackass morwong, is a morwong of the genus Nemadactylus, found off southern Australia, the Atlantic coast of South America, and New Zealand to depths of about 400 m, on all types of bottoms. Its length is between 30 and 60 cm.
The New Zealand rockfish, Acanthoclinus littoreus, is a roundhead of the genus Acanthoclinus, found only in New Zealand from shallow depths to 15 m. Their length is between 5 and 15 cm.

The blue grenadier is a merluccid hake of the family Merlucciidae found around southern Australia and New Zealand, as well as off both the Atlantic and Pacific coasts of South America from Peru to Brazil at depths of between 10 and 1,000 m. It feeds in midwater on small squids, crustaceans, and fish. Its length is between 60 and 120 cm. It is a slender, silvery fish similar in appearance to the gemfish. The meat of the fish is white and almost always sold in fillets.

FishBase is a global species database of fish species. It is the largest and most extensively accessed online database on adult finfish on the web. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.
