Pleurogramminae
''Pleurogrammus'' is a genus of ray-finned fishes belonging to the Family (biology), family Hexagrammidae, the greenlings, known as atka mackerels. These fishes are found in the northwestern Pacific Ocean. Taxonomy ''Pleurogrammus'' was first proposed as a genus in 1861 by the American biologist Theodore Gill with ''Labrax monopterygius'', which had been Species description, described in 1810 by Peter Simon Pallas, as its type species. The genus was placed in the monogeneric subfamily Pleurogramminae within the family Hexagrammidae by E. P. Rutenberg in 1954. Etymology ''Pleurogrammus'' is a compound of ''pleuro'', which means "side", and ''grammus'', meaning "line", a reference to the five lateral line canals on each flank. Species The currently recognized species in this genus are: Characteristics ''Pleurogrammus'' species have no incision in the dorsal fin, or if precent the incision is not deep. The caudal fin is forked and there are 5 lateral lines on each flankl. The up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hexagrammidae
Hexagrammidae, the greenlings, is a family of marine ray-finned fishes belonging to the suborder Cottoidei in the order Scorpaeniformes. These fishes are found in the North Pacific Ocean. Taxonomy Hexagrammidae was first proposed as a family in 1888 by the American ichthyologist David Starr Jordan. The 5th edition of '' Fishes of the World'' clasifies this family as the only family in the monotypic superfamily Hexagrammoidea within the suborder Cottoidei of the diverse order Scorpaeniformes. Other workers have found that if the Scorpaeniformes, as delimited in ''Fishes of the World'', is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes while reclassifying Hexagrammoidea as the infraorder Hexagrammales. The family Zaniolepididae has been included within the Hexagrammidae, as the subfamilies Zaniolepidinae and Oxylebiinae, but ''Fishes of the World'' and Betancur ''et al'' classif ...

Pelagic Fish
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that do live on or near the bottom, and reef fish that are associated with coral reefs. The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of . About 98% of the total water volume is below , and 75% is below . Moyle and Cech, p. 585 Marine pelagic fish can be divided into coastal (inshore) fish and oceanic (offshore) fish. Coastal pelagic fish inhabit the relatively shallow and sunlit waters above the continental shelf, while oceanic pelagic fish inhabit the vast and deep waters beyond the continental shelf (even though they also may swim inshore). Pelagic fish range in size from small coastal forage fish, such as herrings and sardines, to large apex pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Length
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.

Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

William N
William is a male given name of Germanic origin.Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 276. It became very popular in the English language after the Norman conquest of England 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, Wills, Willy, Willie, Bill, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie or the play ''Douglas''). Female forms are Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the given name ''Wilhelm'' (cf. Proto-Germanic ᚹᛁᛚᛃᚨᚺᛖᛚᛗᚨᛉ, ''*Wiljahelmaz'' > German ''Wilhelm'' and Old Norse ᚢᛁᛚᛋᛅᚼᛅᛚᛘᛅᛋ, ''Vilhjálmr'').

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleurogrammus Monopterygius
The Atka mackerel (''Pleurogrammus monopterygius'') is a mackerel in the family Hexagrammidae. Atka mackerel are common in the northern Pacific ocean, and are one of only two members of the genus ''Pleurogrammus'' - the other being the Arabesque greenling (''Pleurogrammus azonus''). The Atka mackerel was named for Atka Island (''Atx̂ax̂'' in Aleut), the largest island of the Andreanof islands, a branch of the Aleutians. Taxonomy The Atka mackerel was originally described under the genus ''Labrax'', but has since been moved to ''Pleurogrammus''. Both names are attributed to Peter Simon Pallas, who published his description of the fish in 1810, roughly a year before his death.*Mearns, Barbara and Richard - ''Biographies for Birdwatchers'' Atka mackerel were once considered to be synonymous with Arabesque greenlings.Nelson, J.S., 1994. Fishes of the World. Wiley, New York. The combined species would have been called the Okhotsk Atka mackerel, a name now used only for the greenlin ...

Charles Wiliam Metz
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depre ...
