Pyxichromis Orthostoma
''Haplochromis orthostoma'' is a species of cichlid fish that is endemic to the Lake Kyoga system in Uganda, where only known from Lake Bisina (a medium-sized lake to the east of Lake Kyoga itself) and Lake Nawampassa (a small lake southeast of Lake Kyoga itself and only separated by a thin swamp). Its continued survival in Lake Bisina is questionable as it has not been recorded in recent surveys, but it still survives in Lake Nawampassa. This piscivorous species is peaceful among similar-sized or larger fish, but will rapidly swallow smaller fish with its very large mouth. The largest officially measured specimen was in standard length, although it has been known to reach about in total length.

Haplochromine
__NOTOC__ The haplochromine cichlids are a tribe of cichlids in subfamily Pseudocrenilabrinae called Haplochromini. This group includes the type genus (''Haplochromis'') plus a number of closely related genera such as '' Aulonocara'', '' Astatotilapia'', and '' Chilotilapia''. They are endemic to eastern, southern and northern Africa, except for ''Astatotilapia flaviijosephi'' in the ''Middle East''. A common name in a scientific context is East African cichlids – while they are not restricted to that region, they are the dominant Cichlidae there. This tribe was extensively studied by Ethelwynn Trewavas, who made major reviews in 1935 and 1989, at the beginning and at the end of her career in ichthyology. Even today, numerous new species are being described each year. The haplochromines were in older times treated as subfamily Haplochrominae, However, the great African radiation of pseudocrenilabrine cichlids is certainly not monophyletic without them, and thus they are t ...

Humphry Greenwood
Peter Humphry Greenwood Fellow of the Royal Society, FRS FIBiol (21 April 1927 – 3 March 1995) was an English ichthyologist. Humphry married fellow student Marjorie George (1924 – 2006) in 1950. He was elected a Fellow of the Royal Society in 1985. He was known for his work on the species flocks of cichlids in the African Great Lakes, and for studies of the phylogeny and systematics of teleosts. Tribute The cichlid fish ''Diplotaxodon greenwoodi'' is named for him. Also ''Brachyaetoides greenwoodi'' Bonde, 2008 is named for him. As is ''Enteromius greenwoodi'' (Max Poll, Poll 1967).

Cichlids
Cichlids are fish from the family (biology), family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the Pholidichthys leucotaenia, convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been Binomial nomenclature, scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain Undescribed taxon, undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rift Valley Lakes
The Rift Valley lakes are a series of lakes in the East African Rift valley that runs through eastern Africa from Ethiopia in the north to Malawi in the south, and includes the African Great Lakes in the south. These include some of the world's oldest lakes, deepest lakes, largest lakes by area, and largest lakes by volume. Many are freshwater ecoregions of great biodiversity, while others are alkaline "soda lakes" supporting highly specialised organisms. The Rift Valley lakes are well known for the evolution of at least 800 cichlid fish species that live in their waters. More species are expected to be discovered. The World Wide Fund for Nature has designated these lakes as one of its Global 200 priority ecoregions for conservation. Geology Lake Malawi and Lake Tanganyika have formed in the various valleys of the East African Rift zone. Ecology Lake Kivu's "still waters ... hide another face: dissolved within are billions of cubic meters of flammable methane and more stil ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish '' Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish '' Astroblepus regani'' * ...
