Liparis Antarcticus
''Liparis antarcticus'' is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes. This species lives in the demersal zone and can be found in the Southeast Pacific Ocean by Chile, and it is the only known species from the genus '' Liparis'' to live in the Southern Hemisphere. ''L. antarcticus'' is known only from its holotype A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described.

Frederic Ward Putnam
Frederic Ward Putnam (April 16, 1839 – August 14, 1915) was an American anthropologist and biologist. Biography Putnam was born and raised in Salem, Massachusetts, the son of Ebenezer (1797–1876) and Elizabeth (Appleton) Putnam. After leaving college, Ebenezer had for a short time engaged in fitting young men for college, but soon went into business in Cincinnati as a commission merchant, a line in which he was successful. Recalled to Salem by his father's death in 1876, Ebenezer married there and devoted himself to the study and cultivation of plants and fruits, and involved himself in the Democratic Party in his county. Although frequently offered office, Ebenezer never accepted, except to serve as alderman in the so-called "model-government" of Salem when that town was first chartered as a city, and as postmaster of Salem. Frederic's early studies were at private schools, and with his father at home. He became curator of ornithology at the Essex Institute in Salem in 1856 ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Liparidae
The snailfishes or sea snails (not to be confused with invertebrate sea snails), are a family of marine ray-finned fishes. These fishes make up the Liparidae, a family classified within the order Scorpaeniformes. 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 are found at depths ranging from shallow coastal waters to more than , including in seven ocean trenches. Taxonomy The snailfish family, Liparidae, was first proposed by the American biologist Theodore Gill in 1861. The 5th edition of ''Fishes of the World'' classifies this family within superfamily Cyclopteroidea, part of the suborder Cottoidei of the order Scorpaeniformes. Other authorities do not recognise this superfamily and classify the two families within it, Cyclopteridae and Liparidae, within the infraorder Cottales alongside the sc ...

Demersal Zone
The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. The demersal zone is just above the benthic zone and forms a layer of the larger profundal zone. Being just above the ocean floor, the demersal zone is variable in depth and can be part of the photic zone where light can penetrate, and photosynthetic organisms grow, or the aphotic zone, which begins between depths of roughly and extends to the ocean depths, where no light penetrates. Fish The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (''Gadus morhua'') is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (''Clupea harengus'') is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel. Two types of fish inhabit the demersal zone: those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Pacific Ocean. Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of , sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández Islands, Juan Fernández, Isla Salas y Gómez, Desventuradas Islands, Desventuradas, and Easter Island, and claims about of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish language, Spanish. Conquest of Chile, Spain conquered and colonized the region in the mid-16th century, replacing Incas in Central Chile, Inca rule; however, they Arauco War ...

Liparis (fish)
''Liparis'' is a large genus of snailfish from the northern hemisphere. They are very common in temperate and cold waters. Chernova (2008) has proposed that the genus should be subdivided into five subgenera: ''Liparis'', ''Neoliparis'', ''Lycocara'', ''Careliparis'', and ''Lyoliparis''. The generic name is from Ancient Greek λιπαρός (''liparos'', " oily"). Species There are currently 60 recognized species in this genus: * '' Liparis adiastolus'' Stein, C. E. Bond & Misitano, 2003 * '' Liparis agassizii'' Putnam, 1874 * '' Liparis alboventer'' ( Krasyukova, 1984) * ''Liparis antarcticus'' Putnam, 1874 * '' Liparis atlanticus'' ( D. S.

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Villa Puerto Edén
Villa Puerto Edén is a Chilean hamlet and minor port located in Wellington Island, in Natales commune, Última Esperanza Province, Magallanes Region. It is considered one of Chile's most isolated inhabited places together with Easter Island and Villa Las Estrellas. The village is known for being the home of the last Kawéshkar people. Owing to the large tidewater glaciers caused by the region’s super-high precipitation, it is only accessible by sea, on the Navimag ferry from Puerto Montt in the north, or Puerto Natales in the south. There is also a monthly boat from Caleta Tortel. The population is 176 (2002 census). Owing to the extraordinarily humid climate the village has no roads, with only pedestrian boardwalks connecting the houses and shops. A weekly transport boat takes local fish and shellfish products (the latter mainly mussels) to markets. Margarita Vargas López, a member of the Chilean Constitutional Convention, was born and raised in Villa Puerto Edén. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Última Esperanza Province
Última Esperanza (, meaning "Province of the Last Hope") is one of four provinces in the southern Chilean region of Magallanes and Antártica Chilena. The capital is Puerto Natales and it is named after Última Esperanza Sound. A section of its border with Argentina in the Southern Patagonian Ice Field is under dispute. Administration As a province, Última Esperanza is a second-level administrative division of Chile, which is further divided into two communes (''comunas''): Puerto Natales and Torres del Paine. The province is administered by a presidentially appointed governor. Ana Ester Mayorga Bahamonde was appointed governor by president Sebastián Piñera. Noted features Within this province, the noted Torres del Paine National Park, Cerro Torre and Cerro Chaltén is located, comprising some of the most spectacular mountain peaks of South America. Also part of the biggest non-polar glacier, the Southern Patagonian Ice Field is within Última Esperanza. Cueva del ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Frederic Ward Putnam
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
