Hawkfish
Cirrhitidae, the hawkfishes, are a family of marine perciform ray-finned fishes found in tropical seas and which are associated with coral reefs. Taxonomy The Cirrhitidae were first recognised as a family by the Scots-born Australian naturalist William Sharp Macleay in 1841. It is one of the 5 constituent families in the superfamily Cirrhitoidea which is classified in the suborder Percoidei of the order Perciformes. Within the Cirrhitoidea, the Cirrhitidae is probably the most basal family. They have been placed in the order Centrarchiformes by some authorities, as part of the superfamily Cirrhitoidea, however, the 5th edition of Fishes of the World does not recognise the Centrarchiformes. The name of the family is taken from that of the genus ''Cirrhitus'' which is derived from ''cirrhus'' meaning a "lock of hair" or "a barbel", thought to be a reference to lower, unbranched rays of the pectoral fins which Bernard Germain de Lacépède termed as “''barbillons''”, which me ...

Cirrhitichthys
''Cirrhitichthys'' is a genus of marine ray-finned fish, hawkfishes, from the family Cirrhitidae. They are found on tropical reefs in the Indian and western Pacific oceans. Some species can be found in the aquarium trade. Taxonomy ''Cirrhitichthys'' was first formally described in 1857 by the Dutch ichthyologist Pieter Bleeker. The type species designated by Bleeker was ''Cirrhites graphidopterus'' which had been described by him in 1853, although this taxon has subsequently been considered a synonym of ''Cirrhites aprinus'' which Georges Cuvier had described in 1829. The name of this genus is a compound of ''Cirrhitus'', referring to the similarity between the two genera, although there are differences in dentition, and ''ichthys'' meaning “fish”. Species The currently recognized species in this genus are: * ''Cirrhitichthys aprinus'' ( G. Cuvier, 1829) (spotted hawkfish) * ''Cirrhitichthys aureus'' ( Temminck & Schlegel, 1842) (yellow hawkfish) * ''Cirrhitichthys bleeke ...

Cirrhitops
''Cirrhitops'' is a genus of marine ray-finned fish, hawkfishes from the family Cirrhitidae. They are found on tropical reefs of the Indian Ocean and the Pacific Ocean. Taxonomy ''Cirrhitops'' was described as a genus in 1951 by the South African ichthyologist J.L.B. Smith with ''Cirrhites fasciatus'' as the type species. When he described the genus Smith stated that it was monotypic as he considered that ''Cirrhites hubbardi'', which had been described in 1941 by the American ichthyologist Leonard P. Schultz, was a synonym of ''C. fasciatus''. The name of the genus has the name of the type genus of the family, ''Cirrhitus'', suffixed with ''ops'' meaning that they species in the genus are similar in appearance to the species in ''Cirrhitus'' and ''Cirrhitichthys''. In 1963 John Ernest Randall reviewed the hawkfish family Cirrhitidae and included two species within the genus, ''C. fasciatus'' and ''C. hubbardi''. In that review he did note that ''C. fasciatus'' had a widely d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirrhitus
''Cirrhitus'' is a genus of marine ray-finned fish, hawkfishes from the family Cirrhitidae. The species in this genus are found on tropical reefs worldwide. Taxonomy ''Cirrhites'' was first formally described as a genus in 1803 by the French naturalist Bernard Germain de Lacépède, Lacépède created it as a monotypic genus for his newly described species from Mauritius, ''Cirrhitus maculatus''. However, it was later shown that Lacépède's ''C. maculatus'' was synonymous with ''Labrus pinnulatus'' described in manuscript by the German naturalist and explorer Johann Reinhold Forster from Tahiti. Forster's was the basis of the description published in 1801 by Johann Gottlob Schneider in his and Marcus Elieser Bloch's ''Systema Ichthyologiae'', although ''Catalog of Fishes'' attributes the name to Forster. The name of this genus is dereived from ''cirrhus'' meaning a "lock of hair" or a "barbel", Lacépède did not explain what he feature the name alludes to. It may be alludin ...

Cirrhitus Pinnulatus
''Cirrhitus pinnulatus'', the stocky hawkfish, whitepsotted hawkfish or marbled hawkfish, is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is found in the Indo-West Pacific region. Taxonomy Cirrhitus pinnulatus was first formally described in 1801 as ''Labrus pinnulatus'' by the German naturalist and explorer Johann Reinhold Forster from Tahiti. Forster's manuscript description was the basis of the description published in 1801 by Johann Gottlob Schneider in his and Marcus Elieser Bloch's ''Systema Ichthyologiae'', although ''Catalog of Fishes'' attributes the name to Forster. When the French naturalist Bernard Germain de Lacépède created the genus ''Cirrhitus'' he placed a single species within it, his own ''Cirrhitus maculatus'' which was later shown to be a synonym of Forster's ''Labrus pinnulatus'', under the name ''C. maculatus'' this species is the type species of its genus. The specific name ''pinnulatus'' means "pinnulated", pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cristacirrhitus
The blackspotted hawkfish (''Cristacirrhitus punctatus'') is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is native to rocky shores of the western Indian Ocean. This species grows to in total length. This species is the only known member of its genus. Taxonomy The blackspotted hawkfish was first formally described in 1829 as ''Cirrhitus punctatus'' by the French zoologist Georges Cuvier with the type locality given as Madagascar. In 2001 John Ernest Randall placed it in a new monotypic genus, ''Cristacirrhitus''. The genus name is a compound of ''crista'' meaning "crest", a reference to the ridge of bone over the eye and ''Cirrhitus'' the type genus of the family Cirrhitidae, in which genus Cuvier had originally placed it. The specific name ''punctatus'' means "spotted", a reference to brown blotches and black spots this species has. Description The black spotted hawkfish has a snout which is not overly elongated and a deep body ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amblycirrhitus
''Amblycirrhitus'' is a genus of ray-finned fishes, hawkfishes belonging to the family Cirrhitidae. These fishes are found on tropical reefs worldwide. Taxonomy ''Amblycirrhitus'' was originally described as a genus in 1862 by the American ichthyologist Theodore Nicholas Gill with the type species designated as ''Cirrhites fasciatus'', which is a synonym of ''Amblycirrhitus pinos'', as this name for a taxon described in 1829 by Cuvier’s was preoccupied. The genus name is a compound of ''ambly'' which means “blunt” which Gill did not explain but which may be an allusion to the “abbreviated” head of the type species or possibly of its “slightly convex” snout, and ''Cirrhitus'', the type genus of family. Species The currently recognized species in this genus are: * ''Amblycirrhitus bimacula'' ( O. P. Jenkins, 1903) (twospot hawkfish) * '' Amblycirrhitus earnshawi'' Lubbock, 1978 * '' Amblycirrhitus oxyrhynchos'' ( Bleeker, 1858) * ''Amblycirrhitus pinos'' ( Mowbra ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Nicholas Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C. Fellow members frequently mocked him for his vanity. He was president of the American Association ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...

Cirrus (biology)
In biology, a cirrus , plural ''cirri'', , (from the Latin ''cirrus'' meaning a ''curl-like tuft or fringe'') is a long, thin structure in an animal similar to a tentacle but generally lacking the tentacle's strength, flexibility, thickness, and sensitivity. In the sheep liver fluke, for example, the ''cirrus'' is the worm's muscular penis and when not in use is retained within a ''cirrus sac'' or ''pouch'' near the animal's head. The same structure exists in the various ''Taenia'' species of tapeworm. In the clam worms, however, the cirrus is the tentacular process or growth on each of the feet (''parpodia''), either the ''dorsal cirrus'' or the ''ventral cirrus'', and has nothing to do with reproduction. Among the bristleworms, a cirrus is a tentacular growth near the head or notopodium containing sense organs and may be either dorsal, ventral, or lamellar. Among the ribbonworms, the ''caudal cirrus'' is a small thread-like growth at the posterior end of the worm. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
