Chrysaora Helvola
''Chrysaora helvola'' is a jellyfish in the family Pelagiidae. Although still recognized as a valid species by the World Register of Marine Species, its taxonomic history is confusing and recent reviews of the genus have not recognized it. Taxonomy '' C. fuscescens'' was described in 1835 by Johann Friedrich von Brandt and three years later he described ''C. helvola'' (a name he preferred), noting that ''C. fuscescens'' was its synonym. This is contrary to the ICZN Code, which states that the oldest name must be used (the younger becomes a junior synonym), but Brandt's publications resulted in confusion and it was only in the 1980s that ''C. fuscescens'' again was recognized as a valid species. Nevertheless, the long history of the name ''C. helvola'' means that it still appears, although recent reviews of the genus have not recognized it.

Johann Friedrich Von Brandt
Johann Friedrich von Brandt (25 May 1802 – 15 July 1879) was a German-Russian natural history, naturalist, who worked mostly in Russia. Brandt was born in Jüterbog and educated at a Gymnasium (school), gymnasium in Wittenberg and the Humboldt University of Berlin, University of Berlin. In 1831 he emigrated to Russia, and soon was appointed director of the Zoological Museum of the St Petersburg Academy of Sciences. Brandt encouraged the collection of native animals, many of which were not represented in the museum. Many specimens began to arrive from the expeditions of Nikolai Alekseevich Severtzov, Severtzov, Nikolai Przhevalsky, Przhevalsky, Aleksandr Fyodorovich Middendorf, Middendorff, Leopold von Schrenck, Schrenck and Gustav Radde. He described several birds collected by Russian explorers off the Pacific Coast of North America, including Brandt's cormorant, red-legged kittiwake and spectacled eider. As a paleontologist, Brandt ranks among the best. He was also an entomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Chrysaora Fuscescens
The Pacific sea nettle (''Chrysaora fuscescens''), or West Coast sea nettle, is a common Plankton, planktonic scyphozoan that lives in the eastern Pacific Ocean from Canada to Mexico. Sea nettles have a distinctive golden-brown bell with a reddish tint. The bell can grow to be larger than one meter (three feet) in diameter in the wild, though most are less than 50 cm across. The long, spiraling, white oral arms and the 24 undulating maroon tentacles may trail behind as far as 15 feet (4.6 m). For humans, its sting is often irritating, but rarely dangerous. ''Chrysaora fuscescens'' has proven to be very popular for display at public aquariums due to their bright colors and relatively easy maintenance. It is possible to establish polyps and culture ''Chrysaora'' in captivity. When provided appropriate aquarium conditions, the medusae do well under captive conditions. Taxonomy Johann Friedrich von Brandt described this species in 1835. The origin of the genus name ''Chrysaora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

ICZN Code
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * Which name must be used in case of name conflicts * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise. The code is meant to guid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysaora Chinensis
''Chrysaora chinensis'', or the Indonesian sea nettle, is a species of jellyfish in the family Pelagiidae. It is native to the central Indo-Pacific region and its sting is considered dangerous. First described by Ernst Vanhöffen in 1888, in 1910 it was considered a variant of '' C. helvola'' and in 1954 it was considered a synonym if it, while other authorities have considered it as a synonym of various other ''Chrysaora'' species. Although the type specimen In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to a ... of ''C. chinensis'' apparently no longer exists, the species of the central Indo-Pacific region is different both from relatives in the northeast Pacific (the region where ''C. helvola'' was described) and those found elsewhere.

Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

Chrysaora
''Chrysaora'' () is a genus of jellyfish, commonly called the sea nettles, in the family Pelagiidae. The origin of the genus name ''Chrysaora'' lies in Greek mythology with Chrysaor, brother of Pegasus and son of Poseidon and Medusa. Translated, ''Chrysaor'' means "he who has a golden armament." Species There are 16 recognized species in the genus ''Chrysaora'': * '' Chrysaora achlyos'' – black sea nettle * '' Chrysaora africana'' * ''Chrysaora agulhensis'' * ''Chrysaora chesapeakei'' - Atlantic bay nettle * '' Chrysaora chinensis'' * ''Chrysaora colorata'' – purple-striped jelly * ''Chrysaora fulgida'' * ''Chrysaora fuscescens'' – Pacific sea nettle * ''Chrysaora helvola'' * ''Chrysaora hysoscella'' – compass jellyfish * ''Chrysaora lactea'' * ''Chrysaora melanaster'' – northern sea nettle * ''Chrysaora pacifica'' – Japanese sea nettle * ''Chrysaora pentastoma'' * ''Chrysaora plocamia'' – South American sea nettle * ''Chrysaora quinquecirrha T ...
