Narcetes Shonanmaruae
''Narcetes shonanmaruae'', the yokozuna slickhead, is a species of marine ray-finned fish, a slickhead belonging to the family Alepocephalidae. It was first formally described in 2021, the description being based on four specimens which were collected below a depth of in Suruga Bay in Japan. Its largest verified size is , however recent footage with a reference has given the fish a much larger estimated length of , however unverified. The specific name references ''Shonan Maru'', the ship the specimens were collected from. The proposed English name, yokozuna slickhead, refers to the highest ranking of sumo wrestler, the yokozuna , or , is the top division of the six divisions of professional sumo. Its size is fixed at 42 wrestlers (''rikishi''), ordered into five ranks according to their ability as defined by their performance in previous tournaments. This is the on ....

Zoology Specimens
A zoological specimen is an animal or part of an animal preserved for scientific use. Various uses are: to verify the identity of a (species), to allow study, increase public knowledge of zoology. Zoological specimens are extremely diverse. Examples are bird and mammal study skins, mounted specimens, skeletal material, casts, pinned insects, dried material, animals preserved in liquid preservatives, and microscope slides. Natural history museums are repositories of zoological specimens Study skins Bird and mammal specimens are conserved as dry study skins, a form of taxidermy. The skin is removed from the animal's carcass, treated with absorbents, and filled with cotton or polyester batting (In the past plant fibres or sawdust were used). Bird specimens have a long, thin, wooden dowel wrapped in batting at their center. The dowel is often intentionally longer than the bird's body and exits at the animal's vent. This exposed dowel provides a place to handle the bird without distu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Masaru Kawato
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yokozuna
, or , is the top division of the six divisions of professional sumo. Its size is fixed at 42 wrestlers (''rikishi''), ordered into five ranks according to their ability as defined by their performance in previous tournaments. This is the only division that is featured on NHK's standard live coverage of sumo tournaments. The lower divisions are shown on their satellite coverage, with only the ''makuuchi'' broadcast having bilingual English commentary. ''Makuuchi'' literally means "inside the curtain", a reference to the early period of professional sumo, when there was a curtained-off area reserved for the top ranked wrestlers, to sit before appearing for their bouts. Wrestlers are considered for promotion or demotion in rank before each grand tournament according to their performance in the one previous. Generally, a greater number of wins than losses (''kachi-koshi'') results in a promotion, and the reverse (''make-koshi'') results in demotion. There are stricter criteria ...

Sumo
is a form of competitive full-contact wrestling where a ''rikishi'' (wrestler) attempts to force his opponent out of a circular ring (''dohyō'') or into touching the ground with any body part other than the soles of his feet (usually by throwing, shoving or pushing him down). Sumo originated in Japan, the only country where it is practiced professionally and where it is considered the national sport. It is considered a ''gendai budō'', which refers to modern Japanese martial arts, but the sport has a history spanning many centuries. Many ancient traditions have been preserved in sumo, and even today the sport includes many ritual elements, such as the use of salt purification, from Shinto. Life as a wrestler is highly regimented, with rules regulated by the Japan Sumo Association. Most sumo wrestlers are required to live in communal sumo training stables, known in Japanese as ''heya'', where all aspects of their daily lives—from meals to their manner of dress—are dic ...

Suruga Bay
Suruga Bay (駿河湾, ''Suruga-wan'') is a bay on the Pacific coast of Honshū in Shizuoka Prefecture, Japan. It is situated north of a straight line from Omaezaki Point to Irōzaki Point at the tip of the Izu Peninsula and surrounded by Honshū to the southwest and west and the Izu Peninsula to the east. Geology Suruga Bay is a place of contrasts. Japan's loftiest peak, Mount Fuji at , rises from the depth of the Suruga Trough running up the middle of the bay, which makes it Japan's deepest. Numerous rivers—especially the major Fuji, the Ōi, and Abe rivers—empty into its western portion, giving that area of the bay a seabed rich in submarine canyons and other geographical features, whereas at the bay's easternmost end, only the Kano River empties into a pocket called Uchiura-wan at Numazu, Shizuoka, where the Izu Peninsula connects to Honshu, giving the water greater transparency and leaving the seabed largely flat except for a number of small rocky islands, some joined ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alepocephalidae
Slickheads, also known as nakedheads or smoothheads, are deep water fishes that belong to the family Alepocephalidae. They are most commonly found in the bathypelagic layer, which is approximately 3000m below the surface. They get their name from the lack of scales on their heads. Similarly, the scientific name is from the Greek ᾰ̓- (''a''-, "not"); λέπος (''lepos'', "scale"); and κεφαλή (''kephalē'', "head"). It has about 22 genera with ca. 96 species. In Japanese they are known as . Description The following characteristics are generally shared by the Alepocephalidae family: Their mouths consist of 80 to 100 razor-sharp teeth, being rather small and feeble. They are shaped in an eel-like elongation, with large eyes, gill rakers that range from moderate to long and numerous, and spineless fins. The single dorsal fin is located posterior to the midpoint of the body and there is no adipose dorsal fin present, there is a pectoral fin ranging from small to rudimenta ...

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
