The Percopsiformes are a small order of freshwater teleost fishes measuring less than 20 cm in length, comprising the trout-perch and its allies. It contains just ten extant species, grouped into seven genera and three families. Five of these genera are monotypic.
John Edward Gray was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The standard author abbreviation J.E.Gray is used to indicate this person as the author when citing a botanical name. The same is used for a zoological name.
The Zeiformes are a small order of exclusively marine ray-finned fishes most notable for the dories, a group of common food fish. The order consists of about 33 species in six extant families, mostly deep-sea types. The boarfishes (Caproidae) have been previously included in this order though they are currently included in the Perciformes.
George Albert Boulenger was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses.
The common name dory is shared by members of several different families of large-eyed, silvery, deep-bodied, laterally compressed, and roughly discoid marine fish. As well as resembling each other, dories are also similar in habit: most are deep-sea and demersal. Additionally, many species support commercial fisheries as food fish. Most dory families belong to the order Zeiformes, suborder Zeioidei:
The Zeidae are a family of large, showy, deep-bodied zeiform marine fish—the "true dories". Found in the Atlantic, Indian, and Pacific Oceans, the family contains just six species in two genera. All species are important and highly regarded food fish supporting commercial fisheries, and some—such as the John Dory —are enjoyed in large public aquaria. These fish are caught primarily by deep-sea trawling.
Arthur Gardiner Butler F.L.S., F.Z.S. was an English entomologist, arachnologist and ornithologist. He worked at the British Museum on the taxonomy of birds, insects, and spiders.
John Dory, St Pierre, or Peter's fish, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible demersal coastal marine fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. Its large eyes at the front of the head provide it with binocular vision and depth perception, which are important for predators. The John Dory's eye spot on the side of its body also confuses prey, which are scooped up in its big mouth.
Paracanthurus hepatus is a species of Indo-Pacific surgeonfish. A popular fish in marine aquaria, it is the only member of the genus Paracanthurus. A number of common names are attributed to the species, including regal tang, palette surgeonfish, blue tang, royal blue tang, hippo tang, blue hippo tang, flagtail surgeonfish, Pacific regal blue tang, and blue surgeonfish.
The New Zealand dory is a dory, in the family Cyttidae, found around southern Australia, and New Zealand, over the continental shelf at depths of between 20 and 400 m. Its length is between 20 and 30 cm.
Pholidophorus is an extinct genus of stem-teleost fish. Numerous species were assigned to this genus in the past, but only the type species Pholidophorus latiusculus, from the Late Triassic of Europe, is considered to be a valid member of the genus today.
Protosphyraena is a fossil genus of swordfish-like marine fish, that thrived worldwide during the Upper Cretaceous Period (Coniacian-Maastrichtian). Though fossil remains of this taxon have been found in both Europe and Asia, it is perhaps best known from the Smoky Hill Member of the Niobrara Chalk Formation of Kansas. Protosphyraena was a large fish, averaging 2–3 metres in length. Protosphyraena shared the Cretaceous oceans with aquatic reptiles, such as mosasaurs and plesiosaurs, as well as with many other species of extinct predatory fish. The name Protosphyraena is a combination of the Greek word protos ("early") plus Sphyraena, the genus name for barracuda, as paleontologists initially mistook Protosphyraena for an ancestral barracuda. Recent research shows that the genus Protosphyraena is not at all related to the true swordfish-family Xiphiidae, but belongs to the extinct family Pachycormidae.
Alectis is a genus of fish in the family Carangidae containing three extant species, all of which are large marine fishes. They are commonly known as threadfish, diamond trevallies or pompanos, although they have no close affiliation with the true pompano genus.
Lookdown usually refers to a single species of fish, Selene vomer
Arthur Loveridge was a British biologist and herpetologist who wrote about animals in East Africa, particularly Tanzania, and New Guinea. He gave scientific names to several gecko species in the region.
Dinopteryx is an extinct genus of prehistoric beardfish from the Late Cretaceous period. It contains a single species, D. spinosus, known from the Santonian of Lebanon. It is the only member of the extinct family Dinopterygidae, which is considered a distinct family of the Polymixiiformes. It was previously placed in the genus Hoplopteryx.
Cyttoides is an extinct genus of prehistoric marine ray-finned fish that lived during the early Oligocene epoch in the seas over Europe. It contains a single species, C. glaronensis from Canton Glarus, Switzerland. It was a zeiform related to the extant genus Cyttus.
Heptanema is an extinct genus of prehistoric coelacanth from the Middle Triassic (Ladinian) of northern Italy and southern Switzerland.
The Myuchelys is a genus of turtles, the Australian saw-shelled turtles, in the family Chelidae and subfamily Chelodininae. They inhabit the headwaters and tributaries of rivers within their range and this led to the name Myuchelys, which is formed from the Aboriginal word myuna meaning clear water and the Greek chelys meaning turtle. They have a short neck and the intergular scute completely separates the gular scutes. They have no alveolar ridge separating them from the snapping turtles of the genus Elseya.
Heterosteus is an extinct genus of heterosteid placoderm of the Middle Devonian known from remains discovered in Europe and Greenland. According to Denison, 1978, Heterosteus might have been planktivorous, along with Homosteus, and Titanichthys.
