Ctenopoma Multispine
''Ctenopoma multispine'', known as the many-spined ctenopoma or climbing perch, is an African freshwater fish. It is up to long and occurs in the Lufira River, Lualaba River, Upemba River, Luapula-Moero in the Democratic Republic of the Congo, Upper Zambezi in Zambia and Okavango River-Lake Ngami in Angola and Botswana. It is also known from the Kafue, rivers of coastal Mozambique, Cuanza River in Angola, and southern tributaries of the Congo River system. It may be found in well-vegetated riverine backwaters, floodplain lagoons, swamps, and isolated pans. This cryptically coloured species feeds on a wide range of prey, including smaller fish, crustaceans, and insects, and hunts by slow stalking. Adults gather in large groups to breed, after which eggs are scattered in suitable places, with no further parental care. The species is capable of surviving in warm, shallow water and may move across high ground in search of better sites in wet weather or at night. This can occur in ...

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he greatly increased the Berlin Museum's herp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuanza River
The Kwanza River, also known as the Coanza, the Quanza, and the Cuanza, is one of the longest rivers in Angola. It empties into the Atlantic Ocean just south of the national capital Luanda. Geography The river is navigable for about from its mouth, located south of Luanda. Its tributaries included the Cutato and Lucala. History The river's navigable lower course was the original route of Portugal invasion into northern Angola. The Capanda Dam in Malanje Province was finished in 2004, providing hydroelectric power to the region and assisting its irrigation. The Cambambe Dam and the Lauca Dam were also constructed on the river. The Caculo Cabaça Hydroelectric Power StationCaculo Cabaça Dam is under construction with estimated completion in 2024. The ''Barra do Kwanza'', the mouth of the river is gradually being developed for tourism, including a golf course. The Church of Nossa Senhora da Victoria stands near the banks of the Kwanza River in Massanganu, Province of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Africa
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...

Ctenopoma
''Ctenopoma'' is a genus of climbing gouramies native to Africa. ''Microctenopoma'' has been included in ''Ctenopoma'' in the past; in contrast to that genus, ''Ctenopoma'' species are egg scatterers with no parental care. Species The 18 currently recognized species in this genus are: * ''Ctenopoma acutirostre'' Pellegrin, 1899 (leopard bush fish or spotted ctenopoma) * ''Ctenopoma argentoventer'' ( C. G. E. Ahl, 1922) (silverbelly ctenopoma) * ''Ctenopoma ashbysmithi'' Banister & R. G. Bailey, 1979 * ''Ctenopoma gabonense'' Günther, 1896 * ''Ctenopoma garuanum'' ( C. G. E. Ahl, 1927) * ''Ctenopoma houyi'' ( C. G. E. Ahl, 1927) * ''Ctenopoma kingsleyae'' Günther, 1896 (tailspot ctenopoma) * ''Ctenopoma maculatum'' Thominot, 1886 * ''Ctenopoma multispine'' W. K. H. Peters, 1844 (many-spined ctenopoma) * ''Ctenopoma muriei'' (Boulenger, 1906) (ocellated labyrinth fish) * ''Ctenopoma nebulosum'' S. M.

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 ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Type Locality (biology)
In biology, a type is a particular 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 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 scientific name of every taxon is almos ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichodinidae
Trichodinidae is a family of ciliates of the order Mobilida, class Oligohymenophorea. Members of the family are ectoparasites (or, alternatively, ectocommensals) of a wide variety of aquatic organisms, including fish, amphibians, hydrozoans, molluscs and crustaceans. Suggestion from an anonymous editor: Trichodina actually infect Hydra too, so someone needs to add that in, along with a citation. Genera The family consists of four genera. * ''Dipartiella'' Stein, 1961 * '' Paratrichodina'' Lom, 1963 * ''Trichodina Trichodina is a genus of ciliate alveolates that is ectocommensal or parasitic on aquatic animals, particularly fish.
