Ovalentaria
Ovalentaria is a clade of ray-finned fishes within the Percomorpha, referred to as a subseries. It is made up of a group of fish families which are referred to in ''Fishes of the World's'' fifth edition as'' incertae sedis'', as well as the orders Mugiliformes, Cichliformes, and Blenniiformes. It was named by W. L. Smith and T. J. Near in Wainwright ''et al.'' (2012) based on a molecular phylogeny, but the authors suggested that the group was united by the presence of demersal eggs that are attached to a substrate. Some authors have used the ordinal name Stiassnyiformes for a clade including Mugiloidei, Plesiopidae, Blenniiformes, Atherinomorpha, and Cichlidae, and this grouping does appear to be monophyletic. Classification In the 5th edition of'' Fishes of the World'', the Ovalentaria are classified as: * ''incertae sedis'' ** Family Ambassidae (Asian glassfishes) ** Family Embiotocidae (surfperches) ** Family Grammatidae (basslets) ** Family Plesiopidae (roundheads) ** F ...

Cichliformes
Cichliformes is an order of fishes. Its members were previously classified under the order Perciformes, but now many authorities consider it to be an independent order within the subseries Ovalentaria. Families There are two families within the Cichliformes; the convict blennies are a small family consisting of a single genus and two species, while the cichlids are one of the largest vertebrate families with over 202 genera and more than 1700 species. It is molecular data which placed the two seemingly dissimilar families in the same taxon. The families are: * Pholidichthyidae D.S. Jordan, 1896 (Convict blennies) * Cichlidae Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted thi ...

Plesiopidae
The longfins, also known as roundheads or spiny basslets, are a family, Plesiopidae, which were formerly placed in the order Perciformes but are now regarded as being ''incertae sedis'' in the subseries Ovalentaria in the clade Percomorpha. They are elongated fishes, found in the Indian Ocean and western Pacific Ocean. Classification In some classifications, the genus ''Notograptus'' is split in its own family, Notograptidae, but FishBase is followed here. There are two subfamilies within the Plesiopidae and the genera are as follows: *Subfamily Acanthoclininae Günther, 1861 ** Genus ''Acanthoclinus'' Jenyns, 1841 ** Genus ''Acanthoplesiops'' Regan, 1912 ** Genus ''Beliops'' Hardy, 1985 ** Genus ''Belonepterygion'' McCulloch, 1915 ** Genus ''Notograptus'' Günther, 1867 * Subfamily Plesiopinae Günther, 1861 ** Genus '' Assessor'' Whitley, 1935 ** Genus ''Calloplesiops'' Fowler and Bean, 1930 ** Genus '' Fraudella'' Whitley, 1935 ** Genus '' Pa ...

Grammatidae
Grammatidae is a small family of ray-finned fishes which were formerly placed in the order Perciformes but are now regarded as being ''incertae sedis'' in the subseries Ovalentaria in the clade Percomorpha. They are commonly known as basslets. They are marine fish found in the tropical western Atlantic Ocean. They are characterized in part by a broken or absent lateral line. The largest species reach around 10 centimeters in maximum length. Some basslets are colorful and are kept in marine aquaria. There are two genera: * '' Gramma'' * ''Lipogramma'' A number of other species may be called "basslets", in particular members of Serranidae, where they may be called "fairy basslets".

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Polycentridae
Leaffishes are small fishes of the family Polycentridae. According to FishBase, it only includes the genera '' Monocirrhus'' and '' Polycentrus'' from fresh and brackish water in tropical South America. Although included in the Asian leaffish family Nandidae by FishBase, most recent authorities place the African '' Afronandus'' and '' Polycentropsis'' in Polycentridae.Collins, R.A., R. Britz, and L. Ruber (2015). Phylogenetic systematics of leaffishes (Teleostei: Polycentridae, Nandidae). J Zoolog Syst Evol Res 53(4). Polycentridae were formerly placed in the order Cichliformes but are now regarded as being ''incertae sedis'' in the subseries Ovalentaria in the clade Percomorpha. All of these fishes are highly specialized ambush predators that resemble leaves, down to the point that their swimming style resembles a drifting leaf (thus the common name leaf fish); when a prey animal - such as an aquatic insect or smaller fish - comes within range, the fish attacks, swallowing the p ...

Pomacentridae
Pomacentridae is a family of ray-finned fish, comprising the damselfishes and clownfishes. This family were formerly placed in the order Perciformes but are now regarded as being ''incertae sedis'' in the subseries Ovalentaria in the clade Percomorpha. They are primarily marine, while a few species inhabit freshwater and brackish environments (e.g., '' Neopomacentrus aquadulcis'', '' N. taeniurus'', '' Pomacentrus taeniometopon'', ''Stegastes otophorus''). They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria. Around 385 species are classified in this family, in about 31 genera. Of these, members of two genera, ''Amphiprion'' and ''Premnas'', are commonly called clownfish or anemonefish, while members of other genera (e.g., ''Pomacentrus'') are commonly called damselfish. The members of this family are classified in four subfamilies: Amphiprioninae, Chrominae, Lepidozyginae, and Pomacentrinae. Etymology Th ...

Atherinomorpha
The Atherinomorpha is a clade of fishes in the superorder Acanthopterygii, the ray-finned fishes, consisting of three orders. The clade is ranked as an infraseries within the subseries Ovalentaria, which in turn is ranked within the wider Percomorpha clade. Characteristics The species within the infraseries Atherinomorpha are generally small fishes which normally grow no longer than , although some needlefishes from the order Beloniformes can grow as long as . The testes of the males are of the restricted spermatogonial type, in which the testes change to reflect a seasonal pattern of reproduction. The females lay demersal eggs with filaments on the chorion. They may or may not have spines in their fins but where these are present they are generally weak. The number of vertebrae is normally less than 24. The pelvic fins are positioned abdominally, subabdominally, or thoracically and may be connected to the pleural rib by a ligament. Ctenoid scales may be present but this is rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mugilidae
The mullets or grey mullets are a family (Mugilidae) of ray-finned fish found worldwide in coastal temperate and tropical waters, and some species in fresh water. Mullets have served as an important source of food in Mediterranean Europe since Roman times. The family includes about 78 species in 20 genera. Mullets are distinguished by the presence of two separate dorsal fins, small triangular mouths, and the absence of a lateral line organ. They feed on detritus, and most species have unusually muscular stomachs and a complex pharynx to help in digestion. Classification and naming Taxonomically, the family is currently treated as the sole member of the order Mugiliformes, but as Nelson says, "there has been much disagreement concerning the relationships" of this family. The presence of fin spines clearly indicates membership in the superorder Acanthopterygii, and in the 1960s, they were classed as primitive perciforms, while others have grouped them in Atheriniformes. They a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opistognathidae
Opistognathidae, the jawfishes, are a family of fishes which have been classified within the order Perciformes, suborder Percoidei but many authorities now classify this family within the clade Ovalentaria and consider that its affinities within that clade are uncertain, i.e. it is ''incertae sedis''. The family includes about 80 species. They are native to warmer parts of the Atlantic, Pacific and Indian Oceans, where found from the shallows to depths of a few hundred meters. The species level taxonomy is complex and the family includes several undescribed species. Physically similar to blennies, most jawfish species are small fish (up to ) with an elongated body plan. A few species, for example the aptly named giant jawfish (''O. rhomaleus''), reaches about . Their heads, mouths, and eyes are large in size relative to the rest of their bodies. Jawfishes possess a single, long dorsal fin with 9-12 spines and a caudal fin that can be either rounded or pointed. Jawfishes typicall ...

Ambassidae
The Asiatic glassfishes are a family, the Ambassidae, of freshwater and marine fishes that were formerly classified in the order Perciformes, but most authorities consider this order to be paraphyletic and that the Ambassidae are of uncertain affinities, ''incertae sedis'', but within the subseries Ovalentaria. The species in the family are native to Asia, Oceania, the Indian Ocean, and the western Pacific Ocean. The family includes eight genera and about 51 species. The largest species reaches a maximum size around 26 cm (10 in). Many of the species are noted for their transparent or semitransparent bodies. Several species are used as aquarium fish, noted for their transparent bodies. The Indian glassy fish (''Parambassis ranga'') is transparent, but showier specimens that had been injected with artificial coloring were sold as novelty pets in the 1990s. Since then, these "painted fish" have become much less popular, with more fishkeepers seeking naturally pigmente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blenniiformes
Blenny (from the Greek and , mucus, slime) is a common name for many types of fish, including several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", grouped under the order Blenniiformes; its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of ''Fishes of the World'' divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes. Families The six "true blenny" families are: * Blenniidae Rafinesque, 1810 - combtooth blennies, including the sabre-toothed blennies * Chaenopsidae Gill, 1865 - pikeblennies, tubeblennies and flagblennies * Clinidae Swainson, 1839 - clinids, inclu ...
