Trumpeter (fish)
Latridae commonly called trumpeters, is a family of marine ray-finned fish. They are found in temperate seas in the Southern Hemisphere. The classification of the species within the Latridae and the related Cheilodactylidae is unclear.They are fished commercially and for sport. Taxonomy Latridae is classified within the superfamily Cirrhitoidea, under the suborder Percoidei of the large order Perciformes. 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. The family has three genera according to the 5th Edition of ''Fishes of the World'', however the authors of that book admit that further studies need to be carried out to resolve the true relationships of all the taxa within the Cirrhitoidea. Latridae was first formally desecrribed as a family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latris Lineata
''Latris lineata'', the striped trumpeter, common trumpeter, copper moki, Hobart-town trumpeter, kokikohi, real trumpeter, Tasmanian striped trumpeter or Tasmanian trumpeter, is a species of marine ray-finned fish belonging to the family Latridae, the trumpeters. It is native to rocky reefs in the temperate oceans of the southern hemisphere. Taxonomy ''Latris lineata'' was first formally described in 1801 as ''Cichla lineata'' by the German naturalist Johann Reinhold Forster with the type locality given as New Zealand. Sir John Richardson described the genus '' Latris'' in his description of ''Latris hecateia'', its only species, and this species was later found to be synonymous with Forster's ''Cichla lineata''. The specific name ''lineata'' means "lined", a reference to the dark horizontal lines in the body. Description ''Latris lineata'' has an elongate, compressed body, with a standard length which is around 3 times its depth, with a relatively long snout and a convex spa ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...

Dactylophora
The dusky morwong (''Dactylophora nigricans'') 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 native to the western and southern coastal reefs of Australia. This species is the only known member of its genus. Taxonomy The dusky morwong was first formally described in 1850 as ''Cheilodactylus nigricans'' by the Scottish naval surgeon, arctic explorer and naturalist Sir John Richardson with the type locality given as King George Sound in Western Australia. In 1883 the English zoologist Charles De Vis created the genus ''Dactylophora'' with this species the type species by monotypy, it is still the only species in the genus. The genus name is a compound of ''dactylus'' meaning "finger" and ''phora'' which means "to bear" or "carry", a reference to the single elongated, unbranched pectoral fin ray. The specific name''nigricans'' means "blackish", as the specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Alphonse Guichenot
Antoine Alphonse Guichenot (31 July 1809 in Paris – 17 February 1876 in Cluny) was a French zoology, zoologist who taught, researched, and participated in specimen collecting trips on behalf of the ''Muséum national d'histoire naturelle'' (Paris), including an extensive biological survey of Algeria. His primary fields of research included fish and reptiles. He is credited with describing the ichthyological genera ''Agonomalus'', ''Neosebastes'' (gurnard scorpionfishes) and ''Glossanodon''.Publications: University series, Volumes 36-40 by Stanford University He also described numerous new species, including the New Caledonian Crested Gecko, New Caledonian crested gecko, ''Correlophus ciliatis'' (changed to ''Rhacodactylus ciliatus'' in 1994, but reclassified as ''Correlophus ciliatis'' in 2012). ...

Mendosoma
''Mendosoma'' is a genus of marine ray finned fish belonging to the family Latridae, the trumpeters. Taxonomy ''Mendosoma'' was first formally described in 1848 by the French zoologist Alphonse Guichenot. Some authorities consider the genus ''Mendosoma'' to be monotypic, but others recognise three species within the genus: * '' Mendosoma caerulescens'' Guichenot, 1848 * '' Mendosoma fernandezianum'' Guichenot 1848 * '' Mendosoma lineatum'' Guichenot, 1848 Both ''M. caerulescens'' and ''M. fernandezianum'' have been considered ''nomina dubia'' in the past. The generic name, ''Mendosoma'', was created by combining the word ''méndola'', a Spanish name for the blotched picarel (''Spicara maena ''Spicara maena'', the blotched picarel, is a species of ray-finned fish native to the eastern Atlantic Ocean, the Mediterranean Sea and the Black Sea.

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] |
Latris (fish)
''Latris'' is a genus of marine ray finned fish belonging to the family Latridae, the trumpeters. They are found in the southern oceans. Taxonomy ''Latris'' was first formally described in 1839 by the Scottish naval surgeon, naturalist and Arctic explorer Sir John Richardson with the type species being ''Latris hecateia'', this being the only species in the genus. Richardson’s name was later shown to be a synonym of Johann Reinhold Forster’s ''Cichla lineata''. The name of the genus, ''Latris'', means “slave” or “servant”, Richardson did not explain why he chose this name. Species There are currently two recognized species in this genus: * '' Latris lineata'' ( J. R. Forster, 1801) (Striped trumpeter) * '' Latris pacifica'' C. D. Roberts, 2003 (Silver trumpeter) Characteristics ''Latris'' has two species which, although molecular analyses suggest that they are sister species, share few obvious derived morphological characteristics which separate them from other ...

Latridopsis
''Latridopsis'' is a genus of marine ray finned fish belonging to the family Latridae, the trumpeters. They are found in the southwestern Pacific Ocean and the southeastern Indian Ocean. Taxonomy ''Latridopsis'' was described in 1862 by the American ichthyologist Theodore Nicholas Gill who designated J.R. Forster's '' Anthias ciliaris'' as its type species, the genus was also monotypic when Gill described it. The name of the genus ''Latridopsis'' means "resembling '' Latris''. Species There are currently two recognized species in this genus: * '' Latridopsis ciliaris'' ( J. R. Forster, 1801) (Blue moki) * '' Latridopsis forsteri'' ( Castelnau, 1872) (Bastard trumpeter) Characteristics ''Latridopsi''s is distinguished from ''Latris'' and '' Mendosoma'' using the following combined characters. They have a somewhat oval and compressed body with a pointed snout and a terminal mouth, which does not have thick, fleshy lips with a slim caudal peduncle. The dorsal fin contains 16-18 rel ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Cheilodactylus
''Cheilodactylus'' is a genus of marine ray-finned fishes belonging to the family Cheilodactylidae, known as morwongs, although this name is not unique to this family. They are found in the temperate waters of the southern hemisphere and in the North Pacific Ocean. Taxonomy ''Cheilodactylus'' was first formally described in 1803 by the French naturalist Bernard Germain de Lacépède when he described ''Cheilodactylus fasciatus'' which was its type species by monotypy. The traditional delimitation of the families Cheilodactlidae and Latridae is based on morphological differences, but the reliability of these differences has been called into doubt, and a phylogenetic analyses and genetics have not supported this arrangement. 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 ''Cheilodactylus fasciatus'' and ' ...
