Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish ''Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish ''Astroblepus regani'' * ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cichlidae
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater a ...

Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the '' Schindleria brevipinguis'' to the marlin in the genus '' Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters ( Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or co ...

Ecuador
Ecuador ( ; ; Quechuan languages, Quechua: ''Ikwayur''; Shuar language, Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechuan languages, Quechua: ''Ikwadur Ripuwlika''; Shuar language, Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's Capital city, capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous peoples in Ecuador, Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was Spanish colonization of the Americas, colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it ...

Andinoacara
''Andinoacara'' is a genus of fish in the family Cichlidae. The genus was described in 2009.Musilova, Rican and Novak, 2009''Phylogeny of the Neotropical cichlid fish tribe Cichlasomatini (Teleostei: Cichlidae) based on morphological and molecular data, with the description of a new genus''.Journal of Zoological Systematics and Evolutionary Research, Volume 47 Issue 3, Pages 209 - 304 (August 2009) Before this the members of ''Andinoacara'' were placed in the " catch-all" genus ''Aequidens'' although they are not closely related to the other members of this genus. The genus ''Andinoacara'' is restricted to freshwater habitats in northwestern South America (Trinidad and the Orinoco Basin west to the Pacific coast of South America as far south as Peru) and southern Central America ( Costa Rica and Panama). There are no members of the genus in the Amazon Basin. Species There are currently eight recognized species in this genus:Eschmeyer, W.N., & R. Fricke, eds. (2013). Catalog of Fis ...

Taxa Named By Charles Tate Regan
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
