Konia (fish)
''Konia'' is a small genus of critically endangered cichlids endemic to Lake Barombi Mbo in western Cameroon. Although generally recognized as distinct, the genus is very close to ''Sarotherodon''.Martin; Cutler; Friel; Touokong; Coop; and Wainwright (2015). Complex histories of repeated gene flow in Cameroon crater lake cichlids cast doubt on one of the clearest examples of sympatric speciation. Evolution 69-6: 1406–1422. The ''Konia'' species are threatened because of pollution and sedimentation due to human activities. They are potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas. ''Myaka'', ''Pungu'' and ''Stomatepia'' are three other equally threatened genera of cichlids that also are endemic to Lake Barombi Mbo. Species There are currently two recognized species in this genus: * ''Konia dikume'' Trewavas, 1972 (Dikume) * ''Konia eisen ...

Ethelwynn Trewavas
Ethelwynn Trewavas (5 November 1900 – 16 August 1993) was an ichthyologist at the British Museum of Natural History. She was known for her work on the families Cichlidae and Sciaenidae. She worked with Charles Tate Regan, another ichthyologist and taxonomist. Academic studies and career She received her bachelor's degree and Board of Education Certificate in Teaching in 1921 from Reading University, and then worked as a teacher before being employed by the King's College of Household and Social Science as a part-time demonstrator, spending most of her time on research. She was taught by Dr. Nellie B. Eales when associated with the Freshwater Biological Association. She met Charles Regan and was employed by him as his assistant until hired by the British Museum (Natural History) as Assistant Keeper in 1935. She was appointed Deputy Keeper of Zoology in 1958, and retired in 1961. She served as the senior scientist in the Fish Section of the British Museum (Natural Histo ...

Pungu
The pungu (''Pungu maclareni'') is a species of cichlid endemic to Lake Barombi Mbo in Cameroon where it prefers shallow waters of about in depth. It feeds on invertebrates, sponges, diatoms and macrophytes. This species can reach a length of SL. It is currently the only known member of its genus, nested within the ''Sarotherodon''.Martin; Cutler; Friel; Touokong; Coop; and Wainwright (2015).

Fish Described In 1962
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Oreochromini
Oreochromini is a tribe of cichlids in the Pseudocrenilabrinae subfamily that is native to Africa and Western Asia, but a few species have been widely introduced to other parts of the world. It was formerly considered to be part of the tribe Tilapini but more recent workers have found that the Tilapini ''sensu lato'' is paraphyletic. Despite this change, species in Oreochromini are still referred to by the common name tilapia and some of the most important tilapia in aquaculture —certain species of ''Oreochromis'' and ''Sarotherodon''— are part of this tribe. In contrast, several species have small ranges and are seriously threatened; a few are already extinct ('' Tristramella sacra'') or possibly extinct (''Oreochromis ismailiaensis'' and '' O. lidole''). Cichlids in the tribe ''Oreochromini'' are mouthbrooders, carrying the eggs and fry in their mouths instead of placing them in a nest. The numerous ''Oreochromis'' species are maternal mouthbrooders, meaning only the femal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Konia Eisentrauti
The konye (''Konia eisentrauti'') is a critically endangered species of fish in the family Cichlidae. It is endemic to Lake Barombi Mbo, a crater lake in western Cameroon.

Konia Dikume
The dikume (''Konia dikume'') is a critically endangered species of fish in the family Cichlidae. It is endemic to Lake Barombi Mbo in western Cameroon. Description The dikume is a silvery coloured fish with faint vertical barring. It grow to a maximum length of 11.2 cm. The most distinguishing feature of this species is that when freshly caught the capillaries swell with blood, particularly at the base of the fins, and oozes out to stain the fishes otherwise silvery skin. Distribution and habitat It is endemic to Lake Barombi Mbo, a volcanic crater lake with a diameter of just 3 miles in western Cameroon where only the top 40 metres contains enough dissolved oxygen to sustain vertebrate life. Habits The dikume is an invertebrate feeder which specialises in feeding on the larvae of the mosquito ''Chaoborus spp''. To reach this food source the dikumbe must spend time in water that is so deep that it is deoxygenated, the high levels of hemoglobin in its blood are an adaptati ...

Stomatepia
''Stomatepia'' is a genus of cichlids endemic to Lake Barombi Mbo in western Cameroon. Although generally recognized as distinct, the genus is very close to ''Sarotherodon''. The ''Stomatepia'' species are all recognized as critically endangered by the IUCN because of pollution and sedimentation due to human activities. They are potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas. '' Konia'', ''Myaka'' and ''Pungu'' are three other equally threatened genera of ciclids that also are endemic to Lake Barombi Mbo.

Myaka
The myaka (''Myaka myaka'') is a critically endangered species of cichlid endemic to Lake Barombi Mbo in western Cameroon. It prefers open, deeper waters where it feeds on phytoplankton and small insects, only venturing into shallower waters to spawn. This species can reach a length of SL. It is currently the only known species in the genus ''Myaka'', but it is very close to ''Sarotherodon''.Martin; Cutler; Friel; Touokong; Coop; and Wainwright (2015).
