Anabantiformes
The Anabantiformes , collectively known as Labyrinth fish. are an order of air-breathing freshwater ray-finned fish with two suborders, five families (Channidae, Aenigmachannidae, Anabantidae, Helostomatidae, and Osphronemidae) and having at least 207 species. In addition, some authorities expand the order to include the suborder Nandoidei, which includes three families - the Nandidae, Badidae and Pristolepididae - that appear to be closely related to the Anabantiformes. The order, and these three related families (classified as ''incertae sedis'' by the 5th edition of ''Fishes of the World''), are part of a monophyletic clade which is a sister clade to the Ovalentaria, the other orders in the clade being Synbranchiformes, Carangiformes, Istiophoriformes and Pleuronectiformes. This clade is sometimes referred to as the Carangaria but is left unnamed and unranked in ''Fishes of the World''. This group of fish are found in Asia and Africa, with some species introduced in U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channidae
The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. They have suprabranchial organs, which are primitive forms of labyrinth organs, that develop when they grow older. The two extant genera are '' Channa'' in Asia and '' Parachanna'' in Africa, consisting of more than 50 species. They are valuable as a food source and have become notorious as an intentionally released invasive species. These fish have been kept as pets but as they get larger, people let them go into ponds, lakes, and rivers, making these fish invasive. Description The various species of snakeheads differ greatly in size; dwarf snakeheads, such as '' Channa orientalis'', do not surpass in length. Most other snakeheads reach between .

Aenigmachannidae
''Aenigmachanna'' is a genus of ray-finned fish in the order Ananbantiformes. It is the only genus in the family Aenigmachannidae, or dragon snakeheads. It contains two species, both of which are largely restricted to subterranean habitats in southwestern India, namely in the Western Ghats foothills in the state of Kerala. Both of the species in this genus display a unique array of traits that distinguish them from their closest living relatives, the true snakeheads in the family Channidae. These include a much longer and more slender body, numerous scales, a very long anal fin, and a lack of ability to maintain buoyancy. Molecular analyses indicate that they split off from Channidae around 34 or 109 MYA. This may indicate that Aenigmachannidae is a uniquely Gondwanan lineage, and if the higher end of estimations is correct, it may have survived the breakup of the Gondwanan supercontinent around 120 MYA. They are unique among cavefish for being one of the few cave-dwelling m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Channa Micropeltes
''Channa micropeltes'', giant snakehead, giant mudfish or toman harimau, is among the largest species in the family Channidae, capable of growing to in length and a weight of . It is native to the fresh waters of Southeast Asia (South Indian populations are now regarded as a separate species, '' C. diplogramma''),Benziger A, Philip S, Raghavan R, Anvar Ali PH, Sukumaran M, et al.

Other names include ''xal mas'' (শাল মাছ) in Assamese, red snakehead, redline snakehead, and ''ikan toman'' (where ''ikan'' is fish in Malay and Indonesian). Biology The young of the ''C.micropeltes'' are red in color, with orange and black lateral stripes appearing after about two months. As the giant snakehead matures, it loses its st ...

Channa
''Channa'' is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many ''Channa'' species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized ''Channa'' species are among the most common staple food fish in several Asian countries, and they are extensively cultured.Kumar, K., R. Kumar, S. Saurabh, M. Sahoo, A.K.

Parachanna
''Parachanna'' is a genus of snakeheads native to freshwater habitats in tropical Africa. Three recognized extant (living) species are in this genus, but a phylogenetic study from 2017 indicates that a fourth, currently undescribed species also exists. One fossil species, '' Parachanna fayumensis'' Murray, 2006 dated to the Upper Eocene and Lower Oligocene is known from the Jebel Qatrani Formation of the Fayum Depression, Egypt. Species The three recognized extant species in this genus are: * '' Parachanna africana'' ( Steindachner, 1879) (African snakehead) * '' Parachanna insignis'' (Sauvage Sauvage, French for "savage" may refer to: ; as a surname: * Catherine Sauvage (1929–1998), a French singer and actress * Cyrille Sauvage (born 1973), a French racing driver * Frédéric Sauvage (1786–1857), a French boat builder who carried ..., 1884) (brown snakehead) * '' Parachanna obscura'' ( Günther, 1861) (obscure snakehead) References * Freshwater fish genera ...

Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Ray-finned Fish Suborders
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 Actinopter ...
