Cheilodactylus Fasciatus
The redfingers (''Cheilodactylus fasciatus'') is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only off the coasts of Namibia and South Africa, in rock pools and from shallow depths to 120 m, on rocky reef areas. Its length is up to 30 cm. Taxonomy The redfingers was first formally described in 1803 by the French naturalist Bernard Germain de Lacépède with the type locality given as the Cape of Good Hope. When Lacépède wrote his description this was the only species in the genus '' Cheilodactylus'' and so is its type species and that of the family Cheilodactylidae. Phylogenetic analyses and genetic studies of the morwongs have not supported the traditional arrangement of the families Cheilodactylidae and Latridae. This has led to some authorities suggesting that the majority of species in Cheilodactylidae should be placed in Latridae. A result of this rearrangement is that the only species ...

Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the '' Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Buffon's Natural History ('' Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''. Meantime he wrote two treatises, ''Essai sur l'électricité'' (1781) and ''Physique générale et partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheilodactylus Pixi
The barred fingerfin (''Cheilodactylus pixi'') is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only in the southeastern Atlantic and southwestern Indian Oceans off the coasts of South Africa. Taxonomy The barred fingerfin was first formally described in 1980 by the South African ichthyologist Margaret Mary Smith with the type locality given as off the mouth of the Kowie River in the Eastern Cape in South Africa. Phylogenetic analyses and genetic studies of the morwongs have not supported the traditional arrangement of the families Cheilodactylidae and Latridae. This has led to some authorities suggesting that the majority of species in Cheilodactylidae should be placed in Latridae. A result of this rearrangement is that the only species which would remain in Cheilodactylidae are this species and '' C. fasciatus'', both from southern Africa. This is because these analyses resolved the genus ''Cheilod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini ( hagfish), Petromyzontiformes ( lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

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 pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironemus
''Chironemus'' is a genus of marine ray finned fish, commonly known as kelpfishes, belonging to the family Chironemidae. They are found in the temperate waters of the Southern Pacific Ocean. Taxonomy The Kelpfishes were placed in the monogeneric family Chironemidae in 1862 by the American ichthyologist Theodore Nicholas Gill. The genus had been described in 1829 by the French zoologist Georges Cuvier when he had described the type species ''Chironemus georgianus''. The family is regarded as part of the superfamily Cirrhitoidea, which is placed within the order Perciformes in the 5th Edition of ''Fishes of the World'', however other authorities place this clade within a new order within the wider Percomorpha, Centrarchiformes. The name of the genus is from Greek ''cheir'' meaning "hands" and ''nema'' meaning "thread". Species The currently recognized species in this genus are: * '' Chironemus bicornis'' (Steindachner, 1898) * '' Chironemus delfini'' ( Porter, 1914) * '' C ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fr ...

Magpie Perch
The magpie perch (''Cheilodactylus (Pseudogoniistius) nigripes''), magpie morwong or black-striped morwong, is a species of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found off southern Australia and northern New Zealand from shallow depths to . Taxonomy The magpie perch was first formally described in 1850 by the Scottish naval surgeon, arctic explorer and naturalist Sir John Richardson with the type locality given as King George Sound in Western Australia. The specific name ''nigripes'' means “black foot”, referring to the colour of the ventral fins on a dried specimen. Although traditionally included in the genus ''Cheilodactylus'' in family Cheilodactylidae, genetic and morphological analyses strongly suggest that it belongs in its own genus, called ''Pseudogoniistius'', which is placed in the family Latridae. The name of the genus is a compound of ''pseudo' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morwong (genus)
''Morwong'' is a genus of marine ray-finned fish traditionally classified as a subgenus within the genus ''Cheilodactylus'' and as belonging to the family Cheilodactylidae found in oceans off Australia and New Zealand. They were formerly included in the genus ''Cheilodactylus'' in family Cheilodactylidae, but based on genetic and morphological analyses they have strongly suggested that the genus ''Morwong'' is a valid genus and should be placed in the family Latridae. Taxonomy ''Morwong'' was first used as a name for a genus in 1957 when the Australian ichthyologist Gilbert Percy Whitley designated ''Cheilodactylus fuscus'' as its type species by monotypy. It was, however, traditionally regarded as synonymous with ''Cheilodactylus''. The genus name is the name in Australian English, the origins of which are unknown, for a number of similar fish species, mostly in the families Cheilodactylidae and Latridae. Although the red morwong has usually been assigned to ''Cheilodactylus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goniistius
''Goniistius'' is a subgenus of marine ray-finned fishes, traditionally classified as being within the genus '' Cheilodactylus'' and belonging to the family Cheilodactylidae, known as morwongs, although this name is not unique to this family and the true taxonomic placement of this taxon requires clarification. They are found in the Pacific Ocean and southeastern Indian Ocean. Taxonomy ''Goniistius'' was created as a subgenus of ''Cheilodactylus'' in 1862 by the American ichthyologist Theodore Nicholas Gill with ''Cheilodactylus zonatus'' designated as its type species. The name of the subgenus is a compound of ''gonio'' meaning “angle” and ''istios'' which means “sail”, Gill did not explain what his name alluded to but he may have been referring to the deep incision between spiny and soft-rayed parts of the dorsal fin of the type species. Genetic and morphological analyses of the family Cheolodactylidae have found that the family as traditionally arranged is polyphyl ...

Chirodactylus
''Chirodactylus'' is a genus of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. They are native to the Atlantic, Indian and eastern Pacific oceans off southern Africa and South America. Taxonomy ''Chirodactylus'' was described as a genus in 1862 by the American ichthyologist Theodore Nicholas Gill with the South American ''Cheilodactylus antonii'', which had been described by Achille Valenciennes in 1833, as the type species by monotypy. Gill subsequently included two other species in ''Chirodactylus'', ''C. grandis'' and ''C, variegatus''. C. antonii was later shown to be a synonym of ''Cheilodactylus variegatus''. Chirodactylus was largely regarded as a synonym of Cheilodactylus until 1980 when the South African ichthyologist Margaret M. Smith resurrected it to include the three southern African species ''C. brachydactylus'', ''C. grandis'' and ''C. jessicalenorum'', as well as ''C ...
