Junior Homonym
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is "valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a '' nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a '' nomen protectum''. :For example: :*Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :* Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotylorhiza Tuberculata
''Cotylorhiza tuberculata'' is a species of jellyfish, of the phylum Cnidaria, also known as the Mediterranean jellyfish, Mediterranean jelly or fried egg jellyfish. It is commonly found in the Mediterranean Sea, Aegean Sea, and Adriatic Sea. Description It can reach in diameter, but is usually less than wide. It seems that this jellyfish's sting has very little or no effect on humans. However it can cause allergies to more sensitive people, these allergies usually involve itching and scratching in the stung area. The cnidarian's smooth, elevated central dome is surrounded by a gutter-like ring. Its marginal lappets are elongated and subrectangular. Each moutharm bifurcates near its base and branches several times. In addition to some larger appendages, there are many short, club-shaped ones that bear disk-like ends. Development ''C. tuberculata'' are the most common jellyfish of their entire order in the Mediterranean Sea. They experience an annual life cycle marked by summer ...

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Cephea
''Cephea'' is a genus of true jellyfish in the family Cepheidae. They are found in the Indo-Pacific and eastern Atlantic oceans. They are sometimes called the crown jellyfish, but this can cause confusion with the closely related genus '' Netrostoma'' or the distantly related species in the order Coronatae. They are also sometimes called the cauliflower jellyfish because of the cauliflower-looking form on top of its bell. Description Habitat Found in tropical, pelagic oceanic regions from the Eastern Central Atlantic to Indo-Western Pacific Lifestyle Lives in a marine environment Relationships Impacts Species According to the ''World Register of Marine Species'', this genus includes the following species: * ''Cephea cephea'' * ''Cephea coerulea ''Cephea'' is a genus of true jellyfish in the family Cepheidae. They are found in the Indo-Pacific and eastern Atlantic oceans. They are sometimes called the crown jellyfish, but this can cause confusion with the c ...

Cotylorhiza
''Cotylorhiza'' is a genus of true jellyfish from the family Cepheidae. The genus is found in the central-east Atlantic, Mediterranean, and western Indian Ocean. Description The genus ''Cotylorhiza'' falls under the family Cepheidae, which includes jellyfish. Species in this genus include '' Cotylorhiza abulacrata, Cotylorhiza erythraea, and Cotylorhiza tuberculata,'' which is the most common species in the genus, as well as in the order '' Rhizostomeae.'' Characterized by eight short oral arms, this genus is pelagic and generally tinted white or yellow and include a sun shade at the top to protect arms and cnidoblasts. First discovered in the Sea of Marmara in the 1700s, the ''Cotylorhiza'' genus had major impacts on species in surrounding areas as it invaded the area. Species reside in pelagic environments in southern European seas, where they impact ecological balances of ecosystem due to resource competitions and rapid reproduction patterns. ''Cotylorhiza'' are among the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marivagia
''Marivagia'' is a monotypic genus of jellyfish, containing only the species, ''Marivagia stellata'', that was first described in 2010 following the discovery of several specimens on the Mediterranean coast of Israel. Etymology The genus name, ''Marivagia'', is derived from the Latin 'mari' (sea) and 'vagus' (wanderer), while the species name is from the Latin 'stella' (star) for the dots and star-burst like pattern on the exumbrella. Identification The earliest specimen of ''Marivagia stellata'' was collected off the coast of Tel Shikmona, at the southern entrance to the port city of Haifa, in 2006. It was photographed, preserved and then sent for identification in Australia, but was lost en route. A larger specimen was collected at nearby Bat Galim on June 29, 2010, while a smaller one was found at Beit Yanai on July 7. Photographs taken in June 2010 off Rosh Hanikra, on the Israeli-Lebanese border, documented live specimens. Characteristics Star-shaped and with a diameter ...

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 opi ...

Jellyfish
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient animal locomotion, locomotion. The tentacles are armed with Cnidocyte, stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex Biological life cycle, life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp (zoology), polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine habitats, marine, but some hydrozoans with a simila ...
