Fundulopanchax Sjostedti
''Fundulopanchax sjostedti'', the blue gularis, golden pheasant gularis or red aphyosemion, is a species of toothcarp endemic to the Niger delta. It is only found in Nigeria and Cameroon. It is named after the Swedish naturalist Bror Yngve Sjöstedt (1866–1948) who collected the type specimen close to a waterfall by the Ndian River, in the Ndian department in Cameroon's Southwest Region. Description This species expresses sexual dimorphism. The males are more colourful and larger than the females, expressing very attractive colours. They outsize all other members of their genus, attaining lengths of . It's a powerful and predatory species, feeding on invertebrates as well as small fish. However it's not the largest species of killifish; note for example the Gulf killifish The Gulf killifish (''Fundulus grandis'') is one of the largest members of the genus ''Fundulus''; it is capable of growing up to 7" in length, whereas the majority of other ''Fundulus'' reach a maxi ...

Cyprinodontiformes
Cyprinodontiformes is an order of ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii. The families of Cyprinodontiformes can be informally divided into three groups based on reproductive strategy: viviparous and ovoviviparous (all species give live birth), and oviparous (all species are egg-laying). The live-bearing groups differ in whether the young are carried to term within (ovoviviparous) or without (viviparous) an enclosing eggshell. Phylogenetically however, one of the two suborders – the Aplocheiloidei – contains oviparous species exclusively, as do two of the fou ...

Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English.

Type (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 almost al ...

Southwest Region (Cameroon)
The Southwest Region or South-West Region () is a region in Cameroon. Its capital is Buea. , its population was 1,553,320. Along with the Northwest Region, it is one of the two Anglophone (English-speaking) regions of Cameroon. Various Ambazonian nationalist and separatist factions regard the ''Sud-Ouest'' region as being distinct as a polity from Cameroon. Administration The region is divided into six divisions or departments: Fako, Koupé-Manengouba, Lebialem, Manyu, Meme, and Ndian. These are in turn broken down into subdivisions. Presidentially appointed senior divisional officers () and subdivisional officers () govern each respectively. Ambazonian separatism Separatists from the Ambazonia administration regard both the Nord-Ouest (Northwest) and Sud-Ouest (Southwest) regions as being constituent components of their envisaged breakaway state. Geography The region was notable for having the first English-speaking university in Cameroon (the University of Buea). Towns i ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Killifish
The Gulf killifish (''Fundulus grandis'') is one of the largest members of the genus ''Fundulus''; it is capable of growing up to 7" in length, whereas the majority of other ''Fundulus'' reach a maximum length of 4". Therefore, ''F. grandis'' is among the largest minnows preyed upon by many sport fish, such as flounder, speckled trout, and red drum. ''Fundulus'' derives from the Latin meaning "bottom," and ''grandis'' means "large". The Gulf killifish is native to the Gulf of Mexico from Texas to Florida and the eastern coast of Florida and the Caribbean Sea in the Atlantic Ocean. Threats to the survival of the Gulf killifish include extreme changes in salinity, changes in temperatures, and toxic events such as the hypoxic dead zone in Louisiana and the Deepwater Horizon oil spill. The Gulf killifish is currently being used to test the effects of oil and oil dispersants on the physiology of marine species affected by these substances. This is significant to conservation biolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fundulopanchax
''Fundulopanchax'' is a genus of killifish living in near-coastal fresh water streams and lakes in Western Africa. All species were previously biologically classified as members of the genus ''Aphyosemion'', with the exception of ''Fundulopanchax avichang'', ''F. gresensi'' and ''F. kamdemi'', which were all scientifically described after the major revision of the ''Aphyosemion'' complex. Etymology The name ''Fundulopanchax'' is composed of the names of two other genera of killifish, '' Fundulus'' Lacépède (1803), which was the genus the type species was originally placed in and '' Panchax'' Valenciennes (1846), as this genus is somewhat intermediate between ''Fundulus'' and ''Aplocheilus'' in characters. Species There are currently 26 recognized species in this genus: * ''Fundulopanchax amieti'' ( Radda, 1976) (Amiet's lyretail) * ''Fundulopanchax arnoldi'' (Boulenger, 1908) (Arnold's killi) * ''Fundulopanchax avichang'' Malumbres & Castelo, 2001 * ''Fundulopanchax ...
