Surgeonfish
Acanthuridae are a family (biology), family of ray-finned fish which includes surgeonfishes, tangs, and Naso (fish), unicornfishes. The family includes about 86 Extant taxon, extant species of ocean, marine fish living in tropical seas, usually around coral reefs. Many of the species are brightly colored and popular in aquarium, aquaria. Etymology and taxonomic history The name of the family is derived from the Greek words ''akantha'' and ''oura'', which loosely translate to "thorn" and "tail", respectively. This refers to the distinguishing characteristic of the family, the "scalpel" found on the caudal peduncle. In the early 1900s, the family was called Hepatidae. Subfamilies and genera Acanthuridae contains the following Neontology, extant subfamilies and genera: * Subfamily Nasinae Henry Weed Fowler, Fowler & Barton Appler Bean, Bean, 1929 ** Genus ''Naso (fish), Naso'' Bernard Germain de Lacépède, Lacépède, 1801 * Subfamily Acanthurinae Charles Lucien Bonaparte, Bonap ...

Acanthurus MH-MCZArtwork ARC 209-030
''Acanthurus'' is a genus of marine ray-finned fish belonging to the family (biology), family Acanthuridae, which includes the surgeonfishes, unicornfishes and tangs, found in the Atlantic Ocean, Atlantic, Indian Ocean, Indian and Pacific Ocean. They are found in tropics, tropical oceans, especially near coral reefs, with most species in the Indo-Pacific but a few are found in the Atlantic Ocean. As other members of the family, they have a pair of Spine (zoology), spines, one on either side of the base of the Caudal fin, tail which are dangerously sharp. Taxonomy ''Acanthurus'' was first proposed as a subgenus of ''Chaetodon'' in 1775 by the Swedish-speaking population of Finland, Swedish-speaking Finnish exploration, explorer, oriental studies, orientalist and natural history, naturalist Peter Forsskål, although he recognised that it was probably different from ''Chaetodon'' even at the family level. In 1856 Eugène Anselme Sébastien Léon Desmarest, Desmarest designated ''Teu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sohal Surgeonfish
The sohal surgeonfish (''Acanthurus sohal'') or sohal tang, is a species of marine ray-finned fish belonging to the family Acanthuridae, which includes the surgeonfishes, unicornfishes and tangs. This fish is found in the northwestern Indian Ocean. Taxonomy The sohal surgeonfish was first formally described in 1775 as ''Chaetodon sohal'' by the Swedish-speaking Finnish naturalist, explorer and orientalist Peter Forsskål with its type locality given as the Red Sea. Forsskål proposed '' Acanthuirus'' as a subgenus of ''Chaetodon'' although he recognised that it was probably different from ''Chaetodon'' even at the family level. In 1856 Desmarest designated ''Teuthis hepatus'', which had been described from a type now known to have been collected at Ambon Island in the Moluccas (other erroneous type localities were named) in 1758 by Linnaeus, as the type species of the genus. ''T. hepatus'' is a synonym of '' Paracanthurus hepatus'' and this would make ''Paracanthurus'' synon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctenochaetus
''Ctenochaetus'', or bristletooth tangs, is a genus of marine ray-finned fish belonging to the family Acanthuridae, which includes the surgeonfishes, unicornfishes and tangs. These fishes are found in the Indo-Pacific region. They have many, small flexible teeth and some species have the common name bristletooth. Taxonomy ''Ctenochaetus'' was first proposed as a genus in 1884 by the American biologist Theodore Gill with ''Acanthurus strigosus'' as its type species. ''A. strigosus'' had originally been described in 1828 by Edward Turner Bennett from the Sandwich Islands. Paraphyly It has been proposed that this genus and ''Acanthurus'' should be merged as otherwise ''Acanthurus'' is paraphyletic. ''Ctenochaetus'' species all nest within ''Acanthurus'', while '' A. nubilis'' and '' A. pyroferus'' are furthermore nested within ''Ctenochaetus''. The 5th edition of ''Fishes of the World'' recognises these two genera as valid and classifies them as the two genera in the tribe Acan ...

Acanthurinae
''Acanthurinae'' is a subfamily of marine ray-finned fishes belonging to the Family (biology), family Acanthuridae, found in the Indo-Pacific and the tropical Atlantic. These fishes commonly have the English names surgeonfishes or tangs. Taxonomy Acanthurinae is the nominate subfamily of the family Acanthuridae which was proposed by the French zoologist Charles Lucien Bonaparte in 1835. The 5th edition of ''Fishes of the World'' recognises 3 Tribe (biology), tribes within the subfamily, the Acanthurini, Prionurini and Zebrasomoni. The other subfamily in the Acanthuridae is the monogeneric Nasinae. Tribes and genera Acanthurinae is subdivided into the following tribes and genera: ''FishBase'' list 57 species in the subfamily, with ''Acanthurus'' containing 40 species being the most speciose genus. Characteristics Acanthurini surgeonfishes are characterised by having 3 spines in the anal fin. They also have one or more mobile and flexible spine on the caudal peduncle, this spin ...

Prionurus
''Prionurus'' is a genus of marine ray-finned fishes belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs, although some of the species in this genus are called sawtails or doctorfish. The species in this genus are found in the Pacific Ocean with one species, ''P. biafraensis'', found in the Atlantic Ocean. Taxonomy ''Prionurus'' was first proposed as a monospecific genus in 1804 by the French naturalist Bernard Germain de Lacépède when he described ''Prionurus microlepidotus''. Lacépède did not give a type locality but the type was collected by François Péron off New South Wales. The genus ''Prionurus'' is the only genus in the tribe Prionurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamiles in the family Acanthuridae. Etymology ''Prionurus'' means "sawtail" a reference to the 3 to 7 immobile keeled bony plates on each side of the caudal peduncle. Species There are currently seven recognized species ...

Paracanthurus
''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 (leading to confusion with the Atlantic species '' Acanthurus coeruleus''), royal blue tang, hippo tang, blue hippo tang, flagtail surgeonfish, Pacific regal blue tang, and blue surgeonfish, hepatus tang, Indo-Pacific blue tang, regal blue surgeonfish, wedge-tailed tang, wedgetail blue tang. It is most closely related to genus '' Zebrasoma'', with which it forms a sister group. Description ''Paracanthurus hepatus'' has a royal blue body, yellow tail, and black "palette" design. Its length at first sexual maturity is 149.2 mm. Adults typically weigh around and males are generally larger than females. The back has a broad black area that encloses at the tip of the pectoral, creating a blue oval on each side of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, ...

Naso (fish)
''Naso'' is a genus of marine ray-finned fishes belonging to the Family (biology), family, Acanthuridae, the unicornfishes, surgeonfishes and tangs. The fishes in this genus are known commonly as unicornfishes because of the "rostral protuberance", a hornlike extension of the forehead present in some species. Unicorn fish are popular with spearfishermen and may be cooked by grilling them whole. Unicornfish primarily live around coral reefs and eat mostly algae. This genus is distributed across the Indo-Pacific from Africa to Hawaii. Taxonomy ''Naso'' was first proposed as a genus in 1801 by Bernard Germain de Lacépède when he Species description, described ''Naso fronticornis'' as a new species from Jeddah and Mauritius. Lacépède's name was an unnecessary replacement of ''Chaetodon unicornis'' described by Peter Forsskål in 1775 from Jeddah. In 1917 David Starr Jordan designated ''Naso fronticornis'' as the type species of the genus ''Naso''. ''Naso'' is the only genus in t ...

Zebrasomini
Zebrasomini is a tribe of marine ray-finned fishes belonging to the family Acanthuridae and it is one of three tribes in the subfamily Acanthurinae. Taxonomy Zebrasomini was first proposed as a taxon in 1933 by American ichthyologist Richard Winterbottom, Winterbottom delineated it as consisting of the two genera ''Zebrasomus'' and ''Paracanthurus'', alongside the monotypic tribe Prionurini and with the remaining two Acanthurine genera, ''Acanthurus'' and ''Ctenochaetus'', being classified in the tribe Acanthurini. These tribes make up the subfamily Acanthurinae which with the subfamily Nasinae make up the family Acanthuridae. Genera There are two genera within the tribe Zebrasomini: * ''Paracanthurus'' Bleeker, 1863 * '' Zebrasoma'' Swainson, 1839 Characteristics The Zebrasomini was defined by Winterbottom using similarities in the osteology of the skull between the two genera and in comparison to the other two Acanthurine tribes, they also have no scales on their larvae.
