Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoarcoidei
Zoarcoidei is a suborder of marine ray-finned fishes belonging to the Order (biology), order Perciformes. The suborder includes the wolffishes, Pholidae, gunnels and eelpouts. The suborder includes about 400 species. These fishes are predominantly found in the North Sea (other), boreal seas of the Northern Hemisphere but they have colonised the Southern Hemisphere. Many members of this suborder are Extremophile, extremophiles adapted to deepwater ecosystems (including Hydrothermal vent, hydrothermal vents) and polar waters. Taxonomy Zoarcoidei was first proposed as a taxonomic grouping by the American zoologist Theodore Gill in 1893 as the Superfamily (biology), superfamily Zoarceoidea. The 5th edition of ''Fishes of the World'' classifies the Zoarcoidei as a suborder within the order Scorpaeniformes. Other authorities classify this taxon as the infraorder Zoarcales within the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes ...

Percomorpha
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including Scombroidei, tuna, Syngnathiformes, seahorses, gobies, Cichlidae, cichlids, flatfish, Labridae, wrasse, Perciformes, perches, Lophiiformes, anglerfish, and Tetraodontiformes, pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant Vertebrate, vertebrates. Evolution Percomorpha are the most biodiversity, diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic Era (geology), 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 extinction event, Cretaceous-Paleogene boundary ago. The oldest known percomorph fossils are of the early Tetraodontiformes, tetraodontiforms ''Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slov ...

Platycephalidae
The Platycephalidae are a Family (biology), family of marine ray-finned fish, most commonly referred to as flatheads. They are relatives of the lionfish, and belong to the order Perciformes. Taxonomy Platycephalidae was first proposed as a family in 1839 by the English naturalist William Swainson. The 5th edition of ''Fishes of the World'' classifies this family within the suborder Platycephaloidei in the Order (biology), order Scorpaeniformes. Other authorities differ and do not consider the Scorpaeniformes to be a valid order because the Perciformes is not monophyletic without the taxa within the Scorpaeniformes being included within it. These authorities consider the Platycephalidae to belong to the suborder Platycephaloidei, along with the families Bembridae, Parabembras, Parabembridae, Hoplichthys, Hoplichthyidae and Plectrogeniinae, Plectrogeniidae within the Perciformes. Genera Platycephalidae has the following 17 genera (including about 86 species) classified within it: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpaenoidei
Scorpaenoidei is a suborder of Actinopterygii, ray-finned fishes, part of the Order (biology), order Perciformes, that includes the scorpionfishes, lionfishes and velvetfishes. This suborder is at its most diverse in the Pacific and Indian Oceans but is also found in the Atlantic Ocean. Taxonomy Scorpaenoidei was first named as a suborder in 1899 by the American ichthyologist Samuel Garman as a suborder of the Perciformes. Some authorities still treat the suborder as being part of the Perciformes but the 5th Edition of ''Fishes of the World'' recognises the Scorpaeniformes as a valid order and places this suborder within it. The subfamilies of the family Scorpaenidae are treated as families by some authors. It has been argued by some authors that the suborder is paraphyletic and that a more correct classification is that the grouping, with some differences, be placed on the Superfamily (biology), superfamily Scorpaenoidea. The earliest known member of the suborder is the Ypresian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottoidei
Cottoidei is a suborder of ray-finned fishes which, according to the 5th edition of ''Fishes of the World'', is placed within the order Scorpaeniformes, alongside the scorpionfishes, flatheads, eelpouts, sticklebacks and related fishes. Taxonomy Cottoidei was first proposed as a taxonomic grouping in 1835 by the Swiss-American zoologist Louis Agassiz. The 5th edition of ''Fishes of the World'' classifies the Cottoidei as a suborder of the order Scorpaeniformes. Other workers have found that if the Scorpaeniformes, as delimited in ''Fishes of the World'', is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes but include the zoarcoids and Sticklebacks and allies as the infraorders Zoarcales and Gasterosteales while reclassifying most superfamilies of ''Fishes of the World'' as infraorders. Subdivisions The Cottoidei is divided into the following superfamilies and families: * Superfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notothenioidei
Notothenioidei is one of 19 suborders of the order Perciformes. The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica. Evolution and geographic distribution The Southern Ocean has supported fish habitats for 400 million years; however, modern notothenioids likely appeared sometime after the Eocene epoch. This period marked the cooling of the Southern Ocean, resulting in the stable, frigid conditions that have persisted to the present day. Another key factor in the evolution of notothenioids is the preponderance of the Antarctic Circumpolar Current (ACC), a large, slow-moving current that extends to the seafloor and precludes most migration to and from the Antarctic region. The earliest known notothenioids are the fossils '' Proeleginops'' and '' Mesetaichthys'' from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpaeniformes
The Scorpaeniformes are a diverse Order (biology), order of Actinopterygii, ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320. They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay: a backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the preoperculum (fish), operculum, to which it is connected in most species. Scorpaeniform fishes are carnivore, carnivorous, mostly feeding on crustaceans and on smaller fish. Most species live on the sea bottom in relatively shallow waters, although species are known from deep water, from the midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral fin, pectoral and caudal fins. Most species are less than in length, but the full size range o ...

Serranidae
Serranidae is a large family (biology), family of fishes belonging to the order Perciformes. The family contains about 450 species in 65 genera, including the sea basses and the groupers (subfamily Epinephelinae). Although many species are small, in some cases less than , the giant grouper (''Epinephelus lanceolatus'') is one of the largest bony fishes in the world, growing to in length and in weight. Representatives of this group live in tropical and subtropical seas worldwide. Characteristics Many serranid species are brightly colored, and many of the larger species are caught commercially for food. They are usually found over reefs, in tropical to subtropical waters along the coasts. Serranids are generally robust in form, with large mouths and small spines on the gill coverings. They typically have several rows of sharp teeth, usually with a pair of particularly large, canine (tooth), canine-like teeth projecting from the lower jaw. All serranids are carnivorous.

Percidae
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains nearly 250 species in 12 genera. The perches and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family. Despite the widespread and speciose nature of this family, the vast majority of its species diversity is within the darters, which are restricted to eastern North America, and the majority of which have small ranges. Excluding the darters, this family contains only 20 species. In Europe, percids were likely a more ecologically dominant group in the past than now, with the immigration of cyprinids to Europe during the Miocene causing a decline in their importance. Characteristics The family is characterised by ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Velvetfish
The red velvetfish (''Gnathanacanthus goetzeei'') is a species of marine ray-finned fish, it is the only species in the monotypic genus ''Gnathanacanthus'' and monogeneric family Gnathanacanthidae. This species is endemic to the inshore waters of western and southern Australia. Taxonomy The red velvetfish was first formally described in 1855 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker with the type locality given as the Derwent River near Hobart in Tasmania. Bleeker classified this new species in the monotypic genus ''Gnathanacanthus''. and in 1893 Theodore Gill classified that genus within the monogeneric family Gnathanacanthidae, The 5th edition of ''Fishes of the World'' classifies the family within the suborder Scorpaenoidei which in turn is classified within the order Scorpaeniformes. Other authorities place the Scorpaenoidei within the Perciformes. A recent study placed the genus ''Gnathanacanthus'' into an expanded stonefish clade, the Synanc ...

Percoidei
Percoidei is a suborder of bony fishes in the order Perciformes. Many commercially harvested fish species are considered to be contained in this suborder, including the groupers, Serranidae, seabasses and perches. Divisions The following classification is based on ''Eschmeyer's Catalog of Fishes'': * Suborder Percoidei ** Family Serranidae William Swainson, Swainson, 1839 (sea basses) ** Family Anthiadidae Felipe Poey y Aloy, Poey, 1861 (fairy basslets or streamer basses) ** Family Epinephelidae Pieter Bleeker, Bleeker, 1874 (groupers) ** Family Liopropomatidae Poey, 1867 (painted basslets) ** Family Grammistidae Bleeker, 1857 (soapfishes) ** Family Percidae Constantine Samuel Rafinesque, Rafinesque, 1815 (perches and Etheostomatinae, darters) ** Family Niphonidae David Starr Jordan, Jordan, 1923 (Ara groupers) ** Family Trachinidae Rafinesque, 1815 (weeverfishes) ** Family Bembropidae Charles Tate Regan, Regan, 1913 (flatheads or duckbill flatheads) Former classification Unti ...

Gasterosteoidei
Gasterosteoidei is a suborder of ray-finned fishes that includes the sticklebacks and relatives, the 5th edition of ''Fishes of the World'' classifies this suborder within the order Scorpaeniformes. Systematics Gasterosteoidei is treated as a suborder within the order Scorpaeniformes in the 5th edition of ''Fishes of the World'', but in other phylogenetic classifications it is treated as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order Zoarciformes. Indostomidae is included within Gasterosteoidei in ''Fishes of the World but according to Betancur ''et al'' its inclusion in the clade renders it paraphyletic and they classify that family within the monotypic suborder Indostomoidei within the Synbranchiformes. Historically, Gasterosteoidei was treated as a suborder within the order Gasterostiformes and often included the sea horses, pipefishes and their relatives as suborder Syngnathoidei, with the sticklebacks a ...
