Eretmodus is a genus of cichlids endemic to Lake Tanganyika in East Africa.
There are currently two recognized species in this genus: [1]
Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared between four countries – Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.
Neolamprologus similis is a shell-dwelling cichlid endemic to Lake Tanganyika where it is only known along the shores of the Democratic Republic of the Congo. N. similis is copper coloured with vertical white stripes running from the head to near the base of the tail. It can reach up to 5 centimetres (2.0 in) in total length. It is a popular freshwater aquarium fish.
Cyphotilapia is a small genus of African cichlids endemic to Lake Tanganyika, with C. frontosa being roughly confined to the northern half of the lake and C. gibberosa roughly to the southern half. They have a distinctly banded pattern, bulbous foreheads when mature and can reach up to 33 cm in length.
Cyprichromis is a genus of cichlids with five species. They are also known as the herring cichlids or sardine cichlids, since they form large schools in the open water of Lake Tanganyika. Of the known species, only C. microlepidotus has been recorded outside Lake Tanganyika.
Neolamprologus is a genus of cichlids endemic to eastern Africa with all but one species, Neolamprologus devosi from the Malagarasi River, occurring in Lake Tanganyika. It is the largest genus of cichlids in Lake Tanganyika and also the largest genus in the tribe Lamprologini, which includes Altolamprologus, Chalinochromis, Julidochromis, Lamprologus, Lepidiolamprologus, Telmatochromis and Variabilichromis. The latter is a monotypic genus doubtfully distinct from Neolamprologus.
Gnathochromis is a small genus of cichlid fish endemic to the Lake Tanganyika basin in East Africa.
Ophthalmotilapia is a small genus of four cichlid species endemic to Lake Tanganyika in East Africa.
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.
Grammatotria lemairii is a species of cichlid endemic to Lake Tanganyika in East Africa where it prefers areas with sandy substrates. This species can reach a length of 26 centimetres (10 in) TL. It is currently the only known member of its genus. The species is occasionally kept as an aquarium fish. The specific name honours Lieutenant Charles Lemaire (1863-1925) who was the leader of the Congo Free State Expedition, which collected specimens of fishes at Lake Tanganyika, including the type of G. lemairii.
Interochromis loocki is a species of cichlid endemic to Lake Tanganyika in East Africa. It is a widespread but rare species living on rocky substrates in 2–3 m (7–10 ft) of water. This species can reach a length of 10.5 centimetres (4.1 in) TL. It is currently the only known member of its genus.
The featherfin cichlid is a species of cichlid endemic to Lake Tanganyika where it is found off rocky slopes. It feeds on plankton. This fish can reach a length of 21 centimetres (8.3 in) TL. It can also be found in the aquarium trade. This is currently the only species recognized in the genus by FishBase, but genetics and morphology suggest there are two valid species. The second is frequently called C. foae in the aquarium trade, but a review of the type specimen is needed to clarify if this is the correct name.
The Tanganyika clown, also known as the striped goby cichlid, is a small species of fish in the family Cichlidae. It is found in the Tanzanian and Zambian shorelines of Lake Tanganyika.
The spotfin goby cichlid is an African species of cichlid endemic to Lake Tanganyika where it is only known from the northern end of the lake. They live amongst pebbles in the surf-zone. This species can reach a length of 7 centimetres (2.8 in) TL. This species can also be found in the aquarium trade. Although presently considered the only species in the genus, another undescribed species is known from the Lukuga River.
Stanleya neritinoides is a species of freshwater snail, an aquatic gastropod mollusk in the family Paludomidae.
Platythelphusa is a genus of freshwater crabs endemic to Lake Tanganyika. It has been placed in a number of families, including a monotypic family, Platythelphusidae, as well as Potamidae and its current position in the Potamonautidae, and has also been treated as a subgenus of Potamonautes. It forms a monophyletic group, possibly nested within the genus Potamonautes, which would therefore be paraphyletic. The genus is the only evolutionary radiation of crabs to have occurred in a freshwater lake, and it occurred recently, probably since the Pliocene. This parallels the better known radiation of cichlid fishes in Lake Tanganyika. Only one other species of freshwater crab is found in Lake Tanganyika, Potamonautes platynotus.
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).
Eretmodini is a tribe of African cichlids. It contains five species of freshwater fish endemic to Lake Tanganyika. They are small fish with reduced swim bladders that are found near the bottom in the turbulent, coastal surf zone. They are mouthbrooders.
Supradapedon is an extinct genus of hyperodapedontine rhynchosaur from mid-late Triassic deposits of Tanganyika Territory, Tanzania. It is known from the holotype SAM-11704. The holotype and only specimen of Supradapedon was first assigned to a species of Scaphonyx, Scaphonyx stockleyi. This species was reassigned to its own genus by Sankar Chatterjee in 1980 and the type species is Supradapedon stockleyi. One study, Langer et al. (2000), concluded that Supradapedon is a synonym of Hyperodapedon and referred it to Hyperodapedon sp. However, the provisional validity of this genus has been commonly accepted since.
Cichlidogyrus jeanloujustinei is a species of monopisthocotylean monogenean in the family Dactylogyridae. It is a parasite of the gills of the fish Eretmodus marksmithi in Lake Tanganyika, Burundi.
Eretmodus marksmithi is a small species of fish in the family Cichlidae. It is found in the northern two thirds to three-fourths of Lake Tanganyika.
