Paratilapia
''Paratilapia'' is a genus of cichlids generally restricted to Madagascar. These are large, dark cichlids densely covered in light spots. An additional very poorly known species from the Congo River basin in mainland Africa is sometimes also placed in the genus, but this is highly questionable and arguably it is better placed in the "Wastebasket taxon, wastebasket genus" ''Haplochromis'' for the time being.Greenwood (1979). ''Towards a phyletic classification of the 'genus' Haplochromis (Pisces, Cichlidae) and related taxa.'' Bulletin of the British Museum (Natural History) Zoology 35(4): 265-322 Taxonomy Phylogenetic analyses of DNA sequence and Morphology (biology), morphological data have hitherto been unable to resolve the relationships of the genus to satisfaction. For example, sequence data from mtDNA MT-RNR2, 16S rRNA and Cytochrome c oxidase, COI disagree regarding its placement, (2004): Molecular phylogeny and biogeography of the Malagasy and South Asian cichlids (Teleo ...

Paratilapia Polleni
''Paratilapia polleni'' is a medium-sized cichlid endemism, endemic to Madagascar. It is also a popular fish for display at public aquarium, aquaria. It is sometimes referred to by the common names starry-night cichlid, polleni cichlid, and black diamond cichlid, while ''marakely'' (black fish) is one of its native names. This species is probably the only known member of its genus, as its current congener, ''P. toddi'', from the African mainland, doubtfully belongs to this genus. Its Specific name (zoology), specific name honours François Pollen (1842-1888), a Netherlands, Dutch naturalist and merchant, who collected the Type (biology), type when visiting Madagascar with fellow Dutch naturalist and explorer Douwe Casparus van Dam (1827-1898). Morphology ''P. polleni'' is a laterally compressed, full-bodied fish. Like most cichlids, it resembles a perch-type fish in shape, hence the Taxonomy (biology), taxonomic designation perciformes - 'perch-like'. Males in captivity devel ...

Ptychochrominae
The Ptychochrominae are a subfamily in the cichlid family of fish. It includes about 14 species. They are restricted to lakes and rivers in Madagascar, and the majority are threatened. Most cichlid genera native to Madagascar are included in this subfamily; the only exceptions are '' Paretroplus'' (subfamily Etroplinae) and ''Paratilapia'' (sometimes included in the Ptychochrominae, but likely belongs in its own subfamily).

Cichlid Genera
Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, order Cichliformes. At least 1,760 species have been scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Cichlids have the largest number of endangered species among vertebrate families, most in the haplochromi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 (1834–1969), 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 ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants.

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...
