Aplodactylus
''Aplodactylus'' is a genus of marine ray-finned fishes, commonly known as marblefishes or sea carps. It is the only genus in the monogeneric family, Aplodactylidae. The fishes in this genus are found in the south eastern Indian Ocean and the southern Pacific Ocean. Taxonomy Aplodactylus was described in 1832 by the French zoologist Achille Valenciennes with ''Aplodactylus punctatus'', which Valenciennes described from the type specimen collected from Valparaiso in Chile, as its only species, being the type species by monotypy. The family had previously contained two genera with the monospecific ''Crinodon'' being recognised as a synonym of ''Aplodactylus'' by Barry C. Russell in 2000. The family, Aplodactylidae was created as Haplodactylidae by the German born British ichthyologist Albert Günther in 1859, the Dutch ichthyologist Pieter Bleeker corrected that to its current name later the same year. The family is regarded as part of the superfamily Cirrhitoidea, which is place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aplodactylus Punctatus
''Aplodactylus punctatus'', the Zamba marblefish, is a species of marine ray finned fish, one of the marblefishes belonging to the family Aplodactylidae. It is found in the eastern Pacific Ocean of the west coast of South America. Taxonomy ''Aplodactylus punctatus'' was first formally described in 1832 by the French zoologist Achille Valenciennes with the type locality given as Valparaiso in Chile. As it was the only species in the new genus ''Aplodactylus'' at the time of its description, it is the type species of that genus. The specific name ''punctatus'' means "spotted". Description ''Aplodactylus punctatus'' has an elongate oblong and compressed body. The small mouth is located ventrally to the snout. The upper lips are fleshy, The teeth in the jaws are made up of three rows of tricuspid incisor like teeth with the outer row being larger than the others. There is a flattened spine on the operculum. The dorsal fin is deeply incised, it contains 16-17 spines and 18-21 sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aplodactylus Arctidens
''Aplodactylus arctidens'', the marblefish or southern seacarp, is a species of marine ray finned fish, one of the marblefishes belonging to the family Aplodactylidae. It is found in the southwestern Pacific Ocean. Taxonomy ''Aplodactylus arctidens'' was first formally described in 1842 by the Scottish naval surgeon, polar explorer and naturalist Sir John Richardson with the type locality given as Port Arthur on Tasmania. The specific name ''arctidens'' is a compound of ''arctatus'' meaning "drawn close together" and ''dens'' meaning "teeth", a reference to the densely packed rows of teeth in both jaws. Description ''Aplodactylus arctidens'' has an elongate body which is one third to one fifth as deep as its standard length. It has a short snout and a rounded head which has a small mouth which is slightly downturned and has fleshy lips, the upper lip projecting. The jaws have small, tricuspid teeth with a few sharply pointed ones too and they are set on 3-4 rows in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aplodactylus Etheridgii
The notchheaded marblefish (''Aplodactylus etheridgii'') is a species of marine ray finned fish, one of the marblefishes belonging to the family Aplodactylidae. It is found in the southwestern Pacific Ocean. Taxonomy The notchheaded marblefish was first formally described in 1889 as ''Haplodactylus etheridgii'' by the Northern Ireland born Australian herpetologist and ichthyologist James Douglas Ogilby with the type locality given as the Admiralty Islets off Lord Howe Island. The specific name of this fish honours the British geologist and paleontologist Robert Etheridge Jr., the leader of the expedition on which the type was collected. Description The notchheaded marblefish has an elongate body which has a depth equivalent to roughly a quarter of its standard length. The largest individuals have a bony ridge above the eye, with the space between the eyes being concave. It has a short snout and a rounded head which has a small mouth which is slightly downturned and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. He studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mouth of the Coppermine River. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrarchiformes
Centrarchiformes is an obsolete order of ray-finned fish, now included amongst the perciformes, with 17 previously included families. This order first appeared about 55.8 million years ago in the Eocene Era, and is composed primarily of omnivores. The order has a wide range that includes the continents of Australia and South America. Many Centrarchiformes look essentially perch-like, featuring a stocky build and a spine-bearing dorsal fin, and range in size from 2.5 cm in length (for '' Elassoma gilberti),'' to 1.8 meters for the '' Maccullochella peelii.'' The order Centrachiformes is not recognized in the 5th Edition of ''Fishes of the World''. Previously included families * Aplodactylidae * Centrarchidae * Cheilodactylidae * Chironemidae * Cirrhitidae * Dichistiidae * Elassomatidae (likely belong within Centrarchidae) * Enoplosidae * Girellidae * Kuhliidae * Kyphosidae * Latridae * Oplegnathidae * Percalatidae * Percichthyidae * Perciliidae * Sinipercidae * Terapon ...

Percomorpha
Percomorpha () is a large clade of ray-finned fish that includes the tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish. Evolution Percomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous-Paleogene boundary ca. 65 Ma ago. Phylogeny External relationships The two cladograms below are based on Betancur-R ''et al.'', 2017. Percomorphs are a clade of teleost fishes.

Fishes Of The World
''Fishes of the World'' by the American ichthyologist Joseph S. Nelson (1937–2011) is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family (biology), family gets at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, while the book generally does not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not involve color illustrations. The fourth edition was the first to incorporate the wide use of DNA analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Cirrhitoidea
Cirrhitoidea is a superfamily within the suborder Percoidei of the large order of ray-finned fishes, the Perciformes. Systematics The Cirrhitoidera has been considered to be a superfamily within the large order Perciformes, within the suborder Percoidei. Molecular studies have also placed the superfamily within the order Centrarchiformes, although the Cirrhitoidea is confirmed as a monophyletic clade. The 5th Edition of Fishes of the World does not recognise Centrarchiformes and retains the superfamily within the order Perciformes. In his 1995 arrangement of the relationship between the families within the Cirrhitoidea Greenwood demonstrated that the Cirrhitidae was likely to be the most basal group, with the Chironemidae as the next most pleisomorphic family, with the remaining three families, Aplodactylidae, Cheilodactylidae, and Latridae having unresolved relationships within the group. A molecular study of 2004 suggested that the Latridae should be expanded to include some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superfamily (biology)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two. Consider a particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
