Paraliparis Membranaceus
''Paraliparis membranaceus'' is a species of snailfish only known from a single specimen of 57 mm standard length collected in Sarmiento Channel in the fjordlands of southern Chile. This species is similar to '' Paraliparis molinai'' but differs in details of dentition and pectoral fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish.

Albert Günther
Albert Karl Ludwig Gotthilf Günther Fellow of the Royal Society, FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen am Neckar, Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snailfish
The Liparidae, commonly known as snailfish or sea snails, are a family of marine scorpaeniform fishes. Widely distributed from the Arctic to Antarctic Oceans, including the oceans in between, the snailfish family contains more than 30 genera and about 410 described species, but there are also many undescribed species. Snailfish species can be found in depths ranging from shallow surface waters to greater than 8,000 meters, and species of the Liparid family have been found in seven ocean trenches. They are closely related to the sculpins (family Cottidae) and lumpfish (family Cyclopteridae). In the past, snailfish were sometimes included within the latter family. Description The snailfish family is poorly studied and few specifics are known. Their elongated, tadpole-like bodies are similar in profile to the rattails. Their heads are large (compared to their size) with small eyes; their bodies are slender to deep, tapering to very small tails. The extensive dorsal and anal ...

Standard 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 (shark Sharks are a group of elasmobranch fish characterize ...

Sarmiento Channel
Sarmiento Channel is a principal Patagonia channel, which extends in a north–south direction. It begins with the Guia Narrows (''Angostura Guía'') and is located in Magallanes y Antártica Chilena Region. The kawésqar people sailed its waters from around 6,000 years ago until end of 20th century, as they inhabited its coasts. The channel is named after Pedro Sarmiento de Gamboa, who was a Spanish explorer who navigated the region's waterways between 1579 and 1580. This elongated water passage begins immediately south of the Guía Narrows at and terminates at the southern tip of Victoria Pass at , where it joins to Smyth Channel. During the first 65 nautical miles, it runs in a general south-southeasterly direction, and is flanked by Chile mainland on the east and Esperanza, Vancouver and Piazzi islands on the west. Then it turns abruptly eastward for about 4 nmi, where the channel's name changes to Farquhar Pass. It then resumes its general SSE course, merging with Colling ...

Fjord
In physical geography, a fjord or fiord () is a long, narrow inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Alaska, Antarctica, British Columbia, Chile, Denmark, Germany, Greenland, the Faroe Islands, Iceland, Ireland, Kamchatka, the Kerguelen Islands, Labrador, Newfoundland, New Zealand, Norway, Novaya Zemlya, Nunavut, Quebec, the Patagonia region of Argentina and Chile, Russia, South Georgia Island, Tasmania, United Kingdom, and Washington state. Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjords when ...

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after ...

Paraliparis Molinai
''Paraliparis'' is a genus of fish in the family Liparidae, the snailfishes. It is found in benthic, benthopelagic and pelagic habitats in all the world's oceans. ''Paraliparis'' species have one pair of nostrils and lack a pseudobranch or ventral suction disc. The generic name means "resembling ''Liparis''."

Pectoral 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 ...

Fish Described In 1887
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...
