Fundulopanchax Gardneri
The blue lyretail (''Fundulopanchax gardneri''), also known as the Gardner's killi and formerly as the steel-blue aphyosemion. It is a species of killifish endemic to freshwater habitats in Nigeria and Cameroon. Description Blue lyretails are sexually dimorphic. The males are more colourful than the females and have wavy lines of red spots which run along its body. The outer margins of the dorsal, anal and caudal fins are tinted with yellow. The females are less brightly coloured and have brown spots rather than red. They grow to a maximum total length of . Distribution The blue lyretail inhabits the tributary streams and marshes of the Benue and Cross River basins of Nigeria and Cameroon. Habitat and biology The blue lyretail occurs in both savanna and forested regions. The males are larger, more colourful and have larger extendable fins than the females. The males are territorial. The waterbodies in which this species occurs are of an unpredictable nature and it has evolved ...

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 ...

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 indiv ...

Fish Keeping
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, serving as a branch of agriculture. Origins of fishkeeping Fish have been raised as food in pools and ponds for thousands of years. Brightly colored or tame specimens of fish in these pools have sometimes been valued as pets rather than food. Many cultures, ancient and modern, have kept fish for both functional and decorative purposes. Ancient Sumerians kept wild-caught fish in ponds, before preparing them for meals. Depictions of the sacred fish of Oxyrhynchus kept in captivity in rectangular temple pools have been found in ancient Egyptian art. Similarly, Asia has experienced a long history of stocking rice paddies with freshwater fish suitable for eating, including various types of catfish and cyprinid. Selective breeding of carp into today's popular and completely domesticated koi and fancy goldfis ...

Fundulopanchax Gardneri Nigerianus Makurdi
''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 ...

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 for ...

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 ...

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 ...

Mamfe
Mamfe or Mamfé is a city in and the capital of Manyu, a division of the Southwest Region in Cameroon. It is from the border of Nigeria, on the Manyu River. It has a population of 36,500 (2017 estimate). It is known as a centre for traditional religion (e.g., Obasinjom and Ekpe Society) and traditional medicine. Mamfe used to be known for bad infrastructure within the city limits, especially the roads, but in recent times the roads have been tarred and are currently in good condition. The roads leading in and out of the city have also been tarred e.g., Mamfe - Bamenda, Mamfe - Kumba, Mamfe - Ekok. The Peace Corps has maintained a presence in the Mamfe area since they entered the country in 1962. Since 2017, Mamfe has been a frequent battleground in the Anglophone Crisis. The city saw heavy fighting in December 2017, when the Cameroonian Army battled the Ambazonia Defence Forces for control over Mamfe and the surroundings. In May 2020, separatist fighters assassinated the new ...
