Esociformes
The Esocoidei () is a small suborder of freshwater Actinopterygii, ray-finned fish, one of two suborders in the order Salmoniformes. It contains two families, Umbridae and Esocidae. The pikes of genus ''Esox'' give the order its name. This order is closely related to the Salmonidae, Salmonoidei, the two comprising the order Salmoniformes. The esociform fishes first appeared in the late Cretaceous — early products of the Euteleost, Euteleostei radiation of that time. They diverged from their sister group Salmonidae, Salmoniformes about 110 million years ago, with the extant species having evolved from a common ancestor that lived about 90 million years ago. Today, they are found in weed-choked freshwater habitats in North America and northern Eurasia. Taxonomy In the past, they were often placed in the order Salmoniformes as the suborder Esocoidei. During the early 21st century, due to their morphological divergence from Salmoniformes, they were instead treated as their own or ...

Esocidae
Esocidae is a family of ray-finned fish in the order Salmoniformes, which contains pike, pickerel, and mudminnows. While the family traditionally only contained the genus ''Esox'', recent genetic and paleontological research have recovered ''Novumbra'' and ''Dallia'' as members of the family Esocidae, being closer related to ''Esox'' than ''Umbra (fish), Umbra''. Fossil specimens from the Mesozoic in North America have been assigned as two additional genera in this family, although they may actually be more basal. Taxonomy The family is classified as follows: * Family Esocidae ** Subfamily Dalliinae David Starr Jordan, Jordan, 1885 *** Genus ''Dallia'' Tarleton Hoffman Bean, Bean, 1880 ** Subfamily Esocinae Constantine Samuel Rafinesque, Rafinesque, 1815 *** Genus ''Esox'' Carl Linnaeus, Linnaeus, 10th edition of Systema Naturae, 1758 *** Genus ''Novumbra'' Leonard Peter Schultz, Schultz, 1929 Classification ''Esox'' is the youngest genus, with ''Dallia'' and ''Novumbra'' br ...

Dallia
''Dallia'' (Blackfish) is a genus of mudminnows native to Russia and Alaska. Molecular data indicates the genus is more closely related to ''Esox'' and ''Novumbra'' than ''Umbra.'' ''Dallia'' diverged from ''Novumbra'' + ''Esox'' approximately 66 million years ago. The genus was named after American naturalist William Healey Dall. Species Three species in this genus are recognized: * '' Dallia admirabilis'' Chereshnev, 1980 (Amguema blackfish) * '' Dallia delicatissima'' Smitt, 1881 (Pilkhykay blackfish) * '' Dallia pectoralis'' T. H. Bean, 1880 (Alaska blackfish) Mitochondrial sequence data was examined from ''D. pectoralis'' and ''D. admirabilis'' and did not indicate that speciation within the genus in Russia; however, genetic isolation within Alaska for populations of ''D. pectoralis'' could be high and associated with karyotype differences. Fossil remains of ''Dallia'' are known from the Late Miocene near Homer, Alaska, suggesting they were found further south in the p ...

Esox Lucius1
''Esox'' is a genus of freshwater fish commonly known as pike or pickerel. It is the type genus of the family Esocidae. The type species of the genus is ''Esox lucius'', the northern pike. ''Esox'' have a fossil record extending back to the Paleocene. Modern large pike species are native to the Palearctic and Nearctic realms, ranging across Northern America and from Western Europe to Siberia in North Asia. Pike have the elongated, torpedo-like shape typical of predatory fishes, with sharply pointed heads and sharp teeth. Their coloration is typically grey-green with a mottled or spotted appearance with stripes along their backs, providing camouflage among underwater weeds, and each individual pike marking patterns are unique like fingerprints. Pikes can grow to a maximum recorded length of , reaching a maximum recorded weight of 67lb 8oz. Etymology The generic name ''Esox'' (pike fish) derives from the Greek ἴσοξ (''ee-soks'', a large fish) and appears to be cognate wit ...

Salmoniformes
Salmoniformes (, lit. "salmon-shaped") is an Order (biology), order of Actinopterygii, ray-finned fishes native to the temperate and subarctic Northern Hemisphere. It contains two suborders: Salmonoidei (containing only the Salmonidae) and Esocoidei (containing pikes and mudminnows). In addition, potential fossil members of the group, dating back to the Late Cretaceous, are also known from Europe and Africa. Both large-sized members of this order (Salmonidae and Esocidae) are important food and Game fish, sport fish of the Northern Hemisphere. Taxonomy The relationship between Salmon, salmons, Pike (fish), pikes, and Umbridae, mudminnows has long been well-attested based on phylogenetic and morphological studies, and all three groups were long placed in the Salmoniformes. In the early 21st century, pikes and mudminnows were split from the Salmoniformes and placed into their own order, Esociformes. However, as recent studies have reaffirmed their close relationship, more recent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonidae
Salmonidae (, ) is a family (biology), family of ray-finned fish, the only extant member of the suborder Salmonoidei, consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids". The family includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), Salvelinus, char, Thymallus, graylings, freshwater whitefishes, taimens and lenoks, all coldwater fish, coldwater mid-trophic level, level predatory fish that inhabit the subarctic and cool temperate waters of the Northern Hemisphere. The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the eponym of the family and order names. Salmonids have a relatively primitive appearance among teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies with rounded fish scale, scales and forked caudal fin, tail fins, and their fish jaw, mouths contain a si ...

Northern Pike
The northern pike (''Esox lucius'') is a species of carnivorous fish of the genus ''Esox'' (pikes). They are commonly found in brackish water, moderately salty and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike (Plural, : pike) in Great Britain, Ireland, most of Eastern Europe, Canada and the United States, U.S., although in the Midwestern United States, they may just be called a Northern. Pike can grow to a relatively large size. Their average length is about , with maximum recorded lengths of up to and maximum weights of . The International Game Fish Association, IGFA currently recognises a pike caught by Lothar Louis on Greffern Lake, Germany, on 16 October 1986, as the all-tackle world-record holding northern pike. Northern pike grow to larger sizes in Eurasia than in North America, and in coastal Eurasian regions than inland ones. Etymology The northern pike gets its common name from its resemblance to the ...

Umbridae
Umbridae is a family of ray-finned fish in the order Salmoniformes. The single living genus, '' Umbra'', occupies weed-choked freshwater habitats in eastern North America and eastern Europe. While the family traditionally contained the genera ''Umbra'', '' Novumbra'', and '' Dallia'', recent genetic and paleontological research have recovered this grouping as paraphyletic, with ''Novumbra'' and ''Dallia'' being moved to the family Esocidae. Distribution Umbridae contains three extant species, all within the genus ''Umbra'': '' Umbra pygmaea'', '' Umbra limi'', and '' Umbra krameri''. ''U. pygmaea'' can be found across the eastern United States and southeastern Canada. ''U. limi'' ranges throughout the Great Lakes region and Mississippi River basin of North America. ''U. krameri'' can be found in the Danube and Dniester River basins of Europe. ''Umbra ''spp. are most commonly found in the Atlantic coast regions of North America, along the marshy, low-oxygen areas of the Mississ ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
