Limia Vittata
The Cuban limia (''Limia vittata''), also known as banded limia, Cuban molly, Cuban topminnow or tabai is a species of livebearing freshwater fish from the family Poeciliidae. The species is native to Cuba where it was endemic but it has been introduced to Hawaii. Description The Cuban limia is olive-green in background colour and has a bluish-grey back, silvery flanks marked with black-edged scales and a white belly. There is a yellow patch close to the vent in fenmles. In the males have the dorsal fin and the anal fin are normally yellow-orange in colour marked with blue-black spots. The females have colorless fins which are marked with a few scattered, black freckles. The females grow to over twice the size of the males which can have a total length of , and females reach . In structure it is a rather robust species, depressed towards the rear with a rounded tail and it has a compressed head which has a small, oblique mouth with a protruding lower jaw and a protractile upper j ...

Alphone Guichenot
Antoine Alphonse Guichenot (31 July 1809 in Paris – 17 February 1876 in Cluny) was a French zoologist who taught, researched, and participated in specimen collecting trips on behalf of the ''Muséum national d'histoire naturelle'' (Paris), including an extensive biological survey of Algeria. His primary fields of research included fish and reptiles. He is credited with describing the ichthyological genera ''Agonomalus'', ''Neosebastes'' (gurnard scorpionfishes) and '' Glossanodon''.Publications: University series, Volumes 36-40 by Stanford University He also described numerous new species, including the , ''Correlop ...

Sailfin Molly
The sailfin molly (''Poecilia latipinna'') is a species of fish of the genus ''Poecilia''. They inhabit fresh, brackish, salt, and coastal waters from North Carolina to Texas and the Yucatán Peninsula of Mexico. Taxonomy The sailfin molly was originally described in 1821 as ''Mollienesia latipinna'' by the naturalist Charles Alexandre Lesueur, who based his description upon specimens from freshwater ponds in the vicinity of New Orleans, Louisiana. However, Lesueur described other collections of the sailfin molly as ''Mollienesia multilineata'' in 1821, the same year in which he described ''M. latipinna''. This conflict created confusion and eventually necessitated a ruling by the International Commission on Zoological Nomenclature (ICZN). In 1959, the ICZN placed precedence on the name ''Mollienesia latipinna'' Lesueur 1821. In a landmark definitive work on poeciliid fishes, Donn Rosen and Reeve Bailey (1959) noted the priority of ''Poecilia'' by Marcus Elieser Bloch and Johan ...

Synonyms (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Limia
''Limia'' is a genus of livebearing fishes belonging to the Cyprinodontiform family Poeciliidae, which includes other livebearers such as platys, swordtails (genus ''Xiphophorous''), guppies and mollies (genus ''Poecilia''). They are found in fresh and brackish water. Of the 21 described ''Limia'' species, 17 are endemic to Hispaniola, one is found on both Hispaniola and Jamaica, and the Cayman Islands, Cuba, and Venezuela have an endemic species each. Limia are popular in aquaria among more advanced hobbyists. Origin and evolution Two schools of thought on the origin of the genus exist. The first suggests that Limia arose from colonization by a seawater-tolerant species that crossed over shallow waters from the North or South American mainland. The strongest evidence for this model is that of the approximately 60 species of freshwater fish in the Antilles, all of them are secondary division freshwater fish. This indicates the ancestors of all fish present on the islands a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Cubans
Cubans ( es, Cubanos) are people born in Cuba and people with Cuban citizenship. Cuba is a multi-ethnic nation, home to people of different ethnic, religious and national backgrounds. Racial and ethnic groups Census The population of Cuba was 11,167,325 inhabitants in 2012. The largest urban populations of Cubans in Cuba (2012) are to be found in Havana (2,106,146), Santiago de Cuba (506,037), Holguín (346,195), Camagüey (323,309), Santa Clara (240,543) and Guantánamo (228,436). According to Cuba's Oficina Nacional de Estadisticas ONE 2012 Census, the population was 11,167,325 including: 5,570,825 men and 5,596,500 women. Source. European In the 2012 Census of Cuba, 64.1% of the inhabitants self-identified as white. Based on genetic testing (2014) in Cuba, the average European, African and Native American ancestry in those auto-reporting to be white were 86%, 6.7%, and 7.8%.

Zoologist
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the ancient world, but after the fall of the Western Roman Empire ...

French People
The French people (french: Français) are an ethnic group and nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily the descendants of Gauls (including the Belgae) and Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norse also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such as Bretons in B ...

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] |
Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, bu ...

Fishkeeping
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.

Gambusia
''Gambusia'' is a large genus of viviparous fish in the family Poeciliidae (order Cyprinodontiformes). ''Gambusia'' contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats. The type species is the Cuban gambusia, ''G. punctata''. The greatest species richness is in Mexico, Texas, and the Greater Antilles, but species are also found elsewhere in the eastern and southern United States, the Bahamas, Central America, and Colombia. ''Gambusia'' species are often called topminnows, or simply gambusias; they are also known as mosquitofish, which, however, refers more specifically to two species, '' G. affinis'' and '' G. holbrooki'', which are often introduced into ponds to eat mosquito larvae. As a consequence, they have been introduced widely outside their native range, and frequently become invasive, threatening local species. They are only occasionally kept in aquariums, due to th ...
