Hyperprosopon Ellipticum
''Hyperprosopon ellipticum'', the silver surfperch, is a species of surfperch native to the Eastern Pacific Ocean. They are one of three species in the genus Hyperprosopon. They may also be known as mojarra ovalada in Mexico. Etymology ''Hyperprosopon'' comes from the greek words "hyper" for "above" or "over," and "prosopon" for "face" or "snout," in reference to the upturned mouth of the species in the genus. The specific name ''ellipticum'' refers to its elliptical, oval-like body outline. Description The body of the Silver surfperch is oval and strongly compressed. The head is small and the mouth is moderately large. The body is silvery with dusky (brownish to gray) coloration on the back, and can have faint dusky bars on the sides. The tail is usually pink with an occasional orange spot on the Fish fin, anal fin. This species can reach a length of fish measurement, TL, but most are under . They can weigh up to .

Hyperprosopon Argenteum
''Hyperprosopon argenteum'', the walleye surfperch, is a species of surfperch native to the Eastern Pacific Ocean. It may also be known as the bigeye perch and chinese pompano. They are one of three species in the genus Hyperprosopon. Description The body of the Walleye surfperch is oval and strongly compressed. The head is small and the eyes are large. The mouth is small and slanted upwards. Its normal colouration is silver with faint dusky shading on the back, and may possess broken, vertical bars on its side. The Walleye surfperch can be distinguished from other surfperch, especially the similar silver surfperch (''H. ellipticum,'') by the distinctive black tips on the pelvic fins, as well as black borders on the tail and anal fins. This species can reach a length of in total length, but are often under . Range Walleye surfperch are found in the Eastern Pacific Ocean from Vancouver Island, British Columbia, Canada to Central Baja California, Mexico, including Guadalupe ...

Hyperprosopon Anale
The spotfin surfperch (''Hyperprosopon anale'') is a species of ray-finned fish from the surfperch Family (biology), family Embiotocidae. It occurs along the western coast of North America from Oregon to Baja California where it occurs in waters down to . It is viviparous and grows to a total length of .

Surfperch
The surfperches are a family of percomorph fishes, the Embiotocidae. They are mainly found in northeast Pacific Ocean (as far south as Baja California), but a few species (genera '' Ditrema'' and '' Neoditrema'') are found in the northwest Pacific, and the tule perch is found in freshwater habitats in California, United States. The largest species in the family, are the barred surfperch (''Amphistichus argenteus'') which reaches up to and , and the rubberlip surfperch (''Rhacochilus toxotes'') which grows to and . They are viviparous fishes, in which the embryo is nourished directly by the mother, as well as the yolk. This gives the family its scientific name, from Greek ''embios'' meaning 'persistent' and ''tokos'' meaning 'birth'. This means the mother fish gives live birth instead of laying eggs. The only known fossil member of the family is '' Eriquius'' from the Late Miocene of California. See also * List of fish families This is a list of fish families sorted alph ...

William Peters Gibbons
William is a masculine given name of Germanic origin. It became popular in England after the Norman conquest in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will or Wil, Wills, Willy, Willie, Bill, Billie, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie). Female forms include Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the German given name ''Wilhelm''. Both ultimately descend from Proto-Germanic ''*Wiljahelmaz'', with a direct cognate also in the Old Norse name ''Vilhjalmr'' and a West Germanic borrowing into Medieval Latin ''Willelmus''. The Proto-Germanic name is a compound of *''wiljô'' "will, wish, desire" and *''helmaz'' "helm, helmet".Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford Unive ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walleye Surfperch (Hyperprosopon Argenteum) And Silver Surfperch (Hyperprosopon Ellipticum)
The walleye (''Sander vitreus'', synonym ''Stizostedion vitreum''), also called the walleyed pike, yellow pike, yellow pikeperch or yellow pickerel, is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a color morph that was once found in the southern Ontario and Quebec regions, but is now presumed extinct. However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification. In parts of its range in English-speaking Canada, the walleye is known as a pickerel, though the fish is not related to the true pickerels, which are members of the family ''Esocidae''. It is also sometimes called a dory in British ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
