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 ...

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] |
Percoidea
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant vertebrates. Evolution Percomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic 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 boundary ago. The oldest known percomorph fossils are of the early tetraodontiforms '' Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slovenia. A higher diversity of early percomorphs is also known from the Campanian of Nardò, Italy, and these also show some level of diversification into modern orders, with representatives of ...

Anthiadidae
Anthias are members of the family Anthiadidae in the order Perciformes. The group has also been called Anthiidae or Anthiinae, but these names are preoccupied by a subfamily of ground beetles in the family Carabidae erected by Bonelli in 1813. Anthias are mostly small, thus are quite popular within the ornamental fish trade. They form complex social structures based on the number of males and females and also their position on the reef itself, and are mainly zooplankton feeders. They occur in all tropical oceans and seas of the world. The first species recognized in this group was described in the Mediterranean and northeast Atlantic and was given name ''Anthias anthias'' by Carl Linnaeus in 1758. Anthias can shoal by the thousands. Anthias do school in these large groups, though they tend toward more intimate subdivisions within the school, appropriately called "harems". These consist of one dominant, colorful male, and two to 12 females — which have their own hierarc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niphonidae
The ara (''Niphon spinosus''), otherwise known as the saw-edged perch or the Dageumbari (다금바리) is a species of marine ray-finned fish from the monospecific genus ''Niphon'' in the Monotypy, monogeneric Family (biology), family Niphonidae. It is found in the Western Pacific Ocean from Japan south to the Philippines where it inhabits rock reefs and inshore waters with rocky sea beds. This species can grow up to in fish measurement, total length. The ara was first formally Species description, described in 1828 by Georges Cuvier in the ''Histoire naturelle des poissons'' which he co-authored with Achille Valenciennes, the Type locality (biology), type locality was given as the Sea of Japan.

Coral Grouper
''Cephalopholis miniata'', also known as the coral grouper, coral hind, coral rock cod, coral cod, coral trout, round-tailed trout or vermillion seabass is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. It is associated with coral reefs and occurs in the Indo-Pacific. Description ''Cephalopholis miniata'' has a body which is 2.6-3.0 times as long in standard length as it is deep. The dorsal profile of the head is flat to slightly convex between the eyes. It has a rounded, finely serrated preopercle, which has a fleshy lower edge. The maxilla extends beyond the rear of the eye. The membranes of the dorsal fin have distinct indentations between the spines. There are 47-56 scales in the lateral line. The dorsal fin has 9 spines and 14-15 soft rays while the anal fin has 3 spines and 8-9 soft rays. The colour of the body is orange-red to reddish brown with many small br ...

Etheostomatinae
Etheostomatinae is a species-rich subfamily of freshwater ray-finned fish, the members of which are commonly known as the darters. The subfamily is part of the family Percidae which also includes the perches, ruffes and pikeperches. The family is endemic to North America. It consists of three to five different genera and well over 200 species. A common name for these fish in southern Indiana is pollywog. Characteristics Species within the Etheostomatinae are all small fish, mostly less than in length, and their bodies are slightly compressed or fusiform in shape. They have two pterygiophores between the first and second dorsal fins which do not have spines and a reduced swimbladder which may be completely lacking. The common name "darter" owes to the behavior of the fish, which dart around their benthic habitat. They are sexually dimorphic; most species have males with bright colors and patterning, particularly when breeding. These colors and patterns are used to attract fema ...

Centrogenyidae
The false scorpionfish (''Centrogenys vaigiensis''), also known as prettyfins, is a species of ray-finned fish, one of three species in the genus ''Centrogenys'', which is the only genus in the Family (biology), family Centrogenyidae. They are pale grey or brown and usually grow no longer than . False scorpionfish are distributed throughout the Indo-West Pacific, bounded by the Ryukyu Islands of Japan to the north and Australia to the south, the Nicobar Islands to the west and New Guinea to the east. Description False scorpionfishes can grow to a maximum length of , but are usually no longer than . The Operculum (fish), operculum (bony covering of gills) has two spines, the lower of which is more conspicuous. False scorpionfish have 36 to 44 lateral line scales. False scorpionfishes have 13 or 14 dorsal fin spines and 9 to 11 branched dorsal rays. The base of the anal fin is short, and has three spines and five segmented rays. The second anal fin spine is the longest. The pectora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latidae
The Latidae, known as the lates perches, are a family of perch-like fish found in Africa, Asia, and the Indian and western Pacific Oceans. Including about 13 species, the family, previously classified subfamily Latinae in family Centropomidae, was raised to family status in 2004 after a cladistic analysis showed the original Centropomidae were paraphyletic. The Latidae are characterised by having dorsal fins that are incompletely separated, or if they are separated, a few isolated spines will be found between the anterior and posterior parts of the fin. Their caudal fin is normally rounded. All species have a vertebral column made up of 25 vertebrae. Many species in this family are important food fishes, and some have been introduced outside their native ranges to provide fishing stocks. The freshwater Nile perch, a fierce predator, has become infamous, as its introduction into Lake Victoria in the 1950s has wrought devastation on the native fishes of the lake, causing the ext ...

Centropomidae
''Centropomus'' is a genus of predominantly marine fish comprising the family Centropomidae. The type species is '' Centropomus undecimalis'', the common snook. Commonly known as snooks or ''róbalos'', the ''Centropomus'' species are native to tropical and subtropical waters of the western Atlantic and eastern Pacific Oceans. Prior to 2004, the subfamily Latinae, which contained three genera, was placed within the Centropomidae; this has since been raised to the family level and renamed Latidae because a cladistic analysis showed the old Centropomidae to be paraphyletic. This has left ''Centropomus'' as the only remaining genus in this family. These are popular game and food fish. Dating from the upper Cretaceous, the centropomids are of typical percoid shape, distinguished by having two-part dorsal fins, a lateral line that extends onto the tail, and frequently, a concave shape to the head. They range from in length and are found in tropical and subtropical waters. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyly
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. 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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
