Oreo (fish)
Oreosomatidae, the oreos, are a family of marine fish. Most species are found in the Southern Hemisphere, inhabiting continental slopes down to about deep. Most of then are 43 cm at most, with the largest species reaching a length of 60 cm. Though they are small, they often have incredibly elongated lifespans, probable result of living in the deep sea (a trait shared with other unrelated fishes like the orange roughy) with the warty oreo being able to live up to 210 years, which puts it at one of the longest living vertebrates on Earth. They borrow their name from the Greek ''oreos (''mountain) and ''somas'' (backs) for the shape of their backs. They are very flattened vertically-laterally, with 5 to 8 rays in their dorsal fin A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Dow Fisher Gilchrist
John Dow Fisher Gilchrist (1866–1926) was a Scottish ichthyologist, who established ichthyology as a scientific discipline in South Africa. He was instrumental in the development of marine biology in South Africa and of a scientifically based local fishing industry. Education and career Gilchrist was born in Anstruther, Fife, Scotland in 1866. His early education was at Madras College, St Andrews, Scotland. He studied at the University of St Andrews and the University of Edinburgh, graduating with a Bachelor of Science (BSc) and a Master of Arts (MA). He was awarded an 1851 Exhibition scholarship for advanced studies and research, which enabled him to study feeding in marine fishes. After further studies at the University of Munich and the University of Zurich he obtained his PhD in geology at Jena University in 1894. He studied marine biology in Naples, Monaco and the Isle of Man before returning to teach zoology at the University of Edinburgh. During his three months at Nap ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

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 cl ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
