Esocoidei
The Esocoidei () is a small suborder of freshwater 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 Salmonoidei, the two comprising the order Salmoniformes. The esociform fishes first appeared in the late Cretaceous — early products of the Euteleostei radiation of that time. They diverged from their sister group 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 order, Esociformes. However, as phylogenetic studie ...

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] |
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 ...

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 ...

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 ...

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 ...

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.

Cretaceous–Paleogene Extinction Event
The Cretaceous–Paleogene (K–Pg) extinction event, also known as the K–T extinction, was the extinction event, mass extinction of three-quarters of the plant and animal species on Earth approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs. Most other tetrapods weighing more than also became extinct, with the exception of some ectothermic species such as sea turtles and crocodilians. It marked the end of the Cretaceous period, and with it the Mesozoic era, while heralding the beginning of the current era, the Cenozoic. In the geologic record, the K–Pg event is marked by a thin layer of sediment called the Cretaceous–Paleogene boundary, K–Pg boundary or K–T boundary, which can be found throughout the world in marine and terrestrial rocks. The boundary clay shows unusually high levels of the metal iridium, which is more common in asteroids than in the Earth's crust. As originally proposed in 1980 by a team of scientists le ...

Charles Lucien Bonaparte
Charles Lucien Jules Laurent Bonaparte, 2nd Prince of Canino and Musignano (24 May 1803 – 29 July 1857) was a French naturalist and ornithology, ornithologist, and a nephew of Napoleon. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte (cardinal), Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp. Lucien was a younger brother of Napoleon I of France, Napoleon I, making Charles the emperor’s nephew. Born in Paris, he was raised in Italy. On 29 June 1822, he married his cousin, Zénaïde Laetitia Julie Bonaparte, Zénaïde, in Brussels. Soon after the marriage, the couple left for Philadelphia in the United States to live with Zénaïde's father, Joseph Bonaparte (who was also the paternal uncle of Charles). Before leaving Italy, Charles had already discovered a Old World warbler, warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new Wilson's storm-petrel ...
