Umbridae
Umbridae is a family of fish in the order Esociformes, which contains pike, pickerel, and mudminnows. 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, l ...

Esociformes
The Esociformes () are a small order of ray-finned fish, with two families, Umbridae and Esocidae. The pikes of genus '' Esox'' give the order its name. This order is closely related to the Salmoniformes, the two comprising the superorder Protacanthopterygii, and are often included in their order. The esociform fishes first appeared in the mid-Cretaceous — early products of the Euteleostei radiation of that time. Today, they are found in weed-choked freshwater habitats in North America and northern Eurasia. Esocidae The three extant esocid genera ('' Esox'', '' Novumbra'', and ''Dallia'') together comprise a holarctic distribution. Two additional genera have been described from fossils dating to the Cretaceous of North America. Umbridae ''Umbra'' remains the only extant species in this family, and can be found in eastern North America and Europe. Three additional genera have been described from fossils dating from the Paleocene of Europe; however, genetic studies on t ...

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).

Dallia
''Dallia'' 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. Species Three species in this genus are recognized: ''Dallia admirabilis'' Chereshnev, 1980 (Amguema blackfish) ''Dallia delicatissima'' Smitt, 1881 (Pilkhykay blackfish) ''Dallia pectoralis The Alaska blackfish (''Dallia pectoralis'') is a species of freshwater fish in the esocid family ( Esocidae) of order Esociformes.

Esocidae
Esocidae is a family of fish in the order Esociformes, 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''. Fossil specimens from the Mesozoic in North America have been assigned as two additional genera in this family. Distribution Esocidae has a holarctic distribution. Species in the genus ''Esox'' can be found in Eurasia and North America, while ''Dallia'' has a more restricted range in Alaska and eastern Siberia. Of extant esocids, ''Novumbra'' has the most restricted range of all, being found only on the Olympic Peninsula in Washington state. Fossils of esocids ''Estesesox'' and ''Oldmanesox'' have been recovered in North America. '' Estesesox'' fossils have been described from the Lance, Hell Creek, Oldman, Foremost, and Milk River Formations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Esox
''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'' has been present in Laurentia (which later became North America) and Eurasia since 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. Pikes 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 . Etymology The generic name ''Esox'' (pike fish) derives from the Greek ἴσοξ (''ee-soks'', a ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Eastern United States
The Eastern United States, commonly referred to as the American East, Eastern America, or simply the East, is the region of the United States to the east of the Mississippi River. In some cases the term may refer to a smaller area or the East Coast plus Illinois, Wisconsin, Indiana, Mississippi, and their border states. In 2011, the 26 states east of the Mississippi (in addition to Washington, D.C. but not including the small portions of Louisiana and Minnesota east of the river) had an estimated population of 179,948,346 or 58.28% of the total U.S. population of 331,745,358 (excluding Puerto Rico). New England New England is a region of the United States located in the northeastern corner of the country, bounded by the Atlantic Ocean, Canada and the state of New York, consisting of the modern states of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut.

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
