Cichlid
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 haplochrom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudocrenilabrinae
The Pseudocrenilabrinae are a subfamily in the cichlid family of fishes to which, according to a study from 2004, includes all the Middle Eastern and African cichlids with the exception of the unusual '' Heterochromis multidens'' and the Malagasy species. This subfamily includes more than 1,100 species. Previous authors recognized additional African subfamilies, e.g. the Tilapiinae of Hoedeman (1947), Tylochrominae of Poll (1986), or Boulengerochrominae of Tawil (2001). This subfamily includes the cichlids from the African Great Lakes, such as the utaka and mbuna in Lake Malawi, and various species from Lake Victoria and Lake Tanganyika. The Pseudocrenilabrinae tribes Haplochromini and Oreochromini are widespread in Africa and also found in the Middle East, while Chromidotilapiini, Hemichromini and Tylochromini are primarily West and Central African. The remaining tribes are largely or entirely restricted to Lake Tanganyika. Systematics Apart from the tribes mentioned in ...

It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use Robert (surname), as a surname. Another commonly used form of the name is Rupert (name), Rupert. After becoming widely used in Continental Europe, the name entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Cross River (Nigeria)
Cross River (native name: Oyono) is the main river in southeastern Nigeria and gives its name to Cross River State. It originates in Cameroon, where it takes the name of the Manyu River. Although not long by African standards its catchment has high rainfall and it becomes very wide. Over its last to the sea it flows through swampy rainforest with numerous creeks and forms an inland delta near its confluence with the Calabar River, about wide and long between the cities of Oron on the west bank and Calabar, on the east bank, more than from the open sea. The delta empties into a broad estuary which it shares with a few smaller rivers. At its mouth in the Atlantic Ocean, the estuary is wide. The eastern side of the estuary is in the neighboring country of Cameroon. The major tributary of Cross River is the river Aloma, coming from Benue State to merge with Cross River in Cross River State. Cross River State is connected with a major highway to its sister state Akwa Ibom. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population.

Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.
