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 ...

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 ...

Umbra (fish)
''Umbra'' is a genus of mudminnows native to Europe and North America. It is the only extant member of the family Umbridae. Phylogenetic evidence suggests the North American and European clades split between the Late Cretaceous or early Paleogene, making this a rather ancient group. Species The currently recognized species in this genus are: * '' Umbra krameri'' Walbaum, 1792 (European mudminnow) * '' Umbra limi'' ( Kirtland, 1840) (central mudminnow) * ''Umbra pygmaea'' ( DeKay, 1842) (eastern mudminnow) The following fossil species are also known: * †'' Umbra euronota'' Schwarzhans ''et al''., 2024 - Middle Miocene of Ukraine otolith">otolith.html" ;"title="nowiki/>otolith">nowiki/>otolithref name=":1"> * † ''Umbra irtyshensis'' Sytchevskaya, 1968 * †'' Umbra irtyshensis">''Umbra irtyshensis'' Sytchevskaya, 1968 * †''Umbra longidorsalis'' Böhme, 2004 - Early Miocene">Umbra longidorsalis">Umbra irtyshensis">''Umbra irtyshensis'' Sytchevskaya, 1968 * †''Umbra lon ...

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] |
Novumbra
''Novumbra'' is a genus of mudminnows (family Umbridae) native to Oregon and Washington state, USA. Molecular data suggests that this genus is more closely related to ''Esox'' than '' Dallia'' and '' Umbra''. ''Novumbra'' diverged from ''Esox'' roughly 65 million years ago in the Paleocene The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), .... Species Two species in this genus are recognized: *'' Novumbra hubbsi'' L. P.

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 ...

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 ...

Umbra Pygmaea
The eastern mudminnow (''Umbra pygmaea'') is a species of freshwater fish belonging to the family Umbridae. It is native to eastern North America, but has been introduced to Europe. It feeds primarily on insect larvae and other small aquatic invertebrates. Description It is an elongated, stout-bodied fish, brown or yellow-green in color, with about 10 or more dark, narrow, lateral stripes separated by pale spaces, although there is no lateral line on the fish. The pelvic fin lies somewhat farther back on the body, such that it rests below the dorsal fin. The body is elongated, and the maximum size of the fish is . Distribution and habitat The native range of the eastern mudminnow is from New York to Florida, and found as west as Georgia. It has also been introduced to Europe, where it can be found in France, Belgium, Germany, the Netherlands, Denmark, and Poland. It is generally found in still or slow-moving waters, often in dense vegetation, often over heavily vegetated s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbra Limi
The central mudminnow (''Umbra limi'') is a small fish in the family Umbridae of the order Esociformes. It is found in central and eastern North America in productive waters. It is fairly tolerant of low oxygen concentration In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: '' mass concentration'', '' molar concentration'', '' number concentration'', ...s and, as a result, it is sometimes the only, or one of a very few, fish species present in waters susceptible to winter or summer kill. Description The central mudminnow lives in slow-moving water around ponds, lakes, and streams in central North America, and ranges in length from 51–102 mm. It burrows tail-first in mud and can tolerate low oxygen levels, allowing it to live in waterways unavailable to other fishes. Its coloration matches this habitat, being brownish above with mottled sides and a pale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Esox
''Esox'' is a genus of freshwater fish commonly known as pike or pickerel. It is the type genus of the family (biology), 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.
