Anomalochromis Thomasi
''Anomalochromis'' is a genus of fish in the family Cichlidae, containing the single species ''Anomalochromis thomasi'', the African butterfly cichlid. It is a small cichlid growing to a length of . The natural habitat of ''A. thomasi'' is Sierra Leone, Liberia and Guinea, mainly in smaller streams. The fish are typically found in slightly acidic, oxygen rich water with other west African cichlid genera such as '' Hemichromis'' and '' Pelvicachromis''. This species is found in forest streams, shaded by dense overhanging vegetation where the water is heavily stained with tannins from decaying organic matter and is coloured like tea. In these streams the temperature of the water can approach in the dry season. It can also occur in streams in forest edge habitats. Under stress or when disturbed ''A. thomasi'' can bury itself in the mud, occasionally down to . They form pairs which spawn into the substrate. These pairs are territorial, the female selects a laying site on a leaf or f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

English People
The English people are an ethnic group and nation native to England, who speak the English language, a West Germanic language, and share a common history and culture. The English identity is of Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Romans, and the partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al. Genomic signals of migration and continuity in Britain before the Anglo-Saxons.

Taxa Named By Humphry Greenwood
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] |
Fish Described In 1916
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a vertebrate, true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemichromini
Hemichromini is a tribe of African cichlid 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 ...s. The group consists of 14 species of freshwater fish from two genera: one species in '' Anomalochromis'' and the remaining in '' Hemichromis''.

Type (biology)
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 anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the '' Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Gün ...

Territoriality
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvicachromis
''Pelvicachromis'' is a genus of small (), brightly coloured cichlids from tropical West Africa and Central Africa. They typically inhabit soft, acidic water ( pH 5.6 – 6.9). All species form monogamous pairs and use caves as spawning sites. Most are easily spawned in captivity with adequate water quality. Species There are currently 11 recognized species in this genus: * '' Pelvicachromis drachenfelsi'' Lamboj, Bartel & dell’Ampio, 2014 * '' Pelvicachromis humilis'' Boulenger, 1916 * '' Pelvicachromis kribensis'' Boulenger, 1911 * '' Pelvicachromis pulcher'' Boulenger, 1901 (Rainbow Kribensis) * '' Pelvicachromis roloffi'' Thys van den Audenaerde, 1968 * '' Pelvicachromis rubrolabiatus'' Lamboj, 2004 * '' Pelvicachromis sacrimontis'' Paulo, 1977 (Often mislabelled as ''P. pulcher'') * '' Pelvicachromis signatus'' Lamboj, 2004 * '' Pelvicachromis silviae'' Lamboj, 2013 * '' Pelvicachromis subocellatus'' Günther, 1872 * ''Pelvicachromis taeniatus'' Boulenger, 19 ...
