Crested Bigscale
''Poromitra crassiceps'', commonly called the crested bigscale (also called large-headed midnight fish, crested melamphid, or one-horned melamphaid) is a species of deep sea fish in the ridgehead family. While the fish with the common name crested bigscale in Alaskan waters had formerly been identified as ''P. crassiceps'', it is now believed that Alaskan crested bigscales are actually ''Poromitra curilensis'', and that ''P. crassiceps'' is restricted to the Atlantic Ocean. As a result of this mis-identification, ''P. crassiceps'' is occasionally identified as the largest ridgehead - while specimens of ''P. curilensis'' as large as 18 cm SL have been found, the maximum length of ''P. crassiceps'' is 14.8 cm SL. Although almost no light penetrates to the deep sea from the surface, the crested bigscale has evolved features that make it practically invisible. Like other deep sea fish, it needs to avoid being seen by predators, some of which hunt for prey by creating their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deep Sea Fish
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridgehead
Ridgeheads, also known as bigscales, are a family (Melamphaidae, from the Greek ''melanos'' lackand ''amphi'' y both sides of small, deep-sea stephanoberyciform fish. The family contains approximately 37 species in five genera; their distribution is worldwide, but ridgeheads are absent from the Arctic Ocean and Mediterranean Sea. Although the family is one of the most widespread and plentiful of deep-sea families, none of its members are of interest to commercial fishery. These fish are named for their large scales and pronounced cranial ridges, as well as for their typically dark brown to black coloration. Ridgeheads are the largest and most diverse family of their order. Description Typical of the Stephanoberyciformes, the melamphid body is robust, oblong, subcylindrical, and slightly compressed laterally. The head is large and scaleless, with its profile either bluntly rounded or with a sharp frontal angle; it is conspicuous for its prominent ridges, which are covered ...

Poromitra Curilensis
''Poromitra'' is a genus of ridgeheads. The 22 known species of Poromitra have been divided into five species groups according to variation in preopercle anatomy. A Poromitra curilensis specimen from the Shirshov Institute of Oceanology, obtained on October 7, 1968, marks the first discovery of a Poromitra member in the southeastern Pacific Ocean. Species There are currently 21 recognized species in this genus: * ''Poromitra atlantica'' (Norman, 1929) * ''Poromitra capito'' Goode & T. H. Bean, 1883 * ''Poromitra coronata'' ( Gilchrist & von Bonde, 1924) * ''Poromitra crassa'' Parin & Ebeling, 1980 * ''Poromitra crassiceps'' ( Günther, 1878) (Crested bigscale) * ''Poromitra cristiceps'' ( C. H. Gilbert, 1890) * ''Poromitra curilensis'' Kotlyar, 2008 * ''Poromitra decipiens'' Kotlyar, 2008 * ''Poromitra frontosa'' (Garman, 1899) * ''Poromitra gibbsi'' Parin & Borodulina, 1989 * ''Poromitra glochidiata'' Kotlyar, 2008 * ''Poromitra indooceanica'' Kotlyar, 2008 * ''Poromitra juc ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Copeia
''Ichthyology & Herpetology'' (formerly ''Copeia'') is a quarterly peer-reviewed scientific journal covering research in ichthyology and herpetology that was originally named after Edward Drinker Cope, a prominent American researcher in these fields. It is the official journal of the American Society of Ichthyologists and Herpetologists. According to the ''Journal Citation Reports'', ''Copeia'' has a 2021 impact factor of 1.857, ranking it 65th out of 176 journals in the category "Zoology". History On December 27, 1913, John Treadwell Nichols published the first issue of ''Copeia''. This issue consisted of a single piece of paper folded to form four pages of information with five articles. The cover of the pamphlet bore the inscription: "Published by the contributors to advance the science of coldblooded vertebrates." In 2020, the American Society of Ichthyologists and Herpetologists voted to rename the journal, Ichthyology & Herpetology. Name change The journal was na ...
