Xenotilapia Rotundiventralis
''Xenotilapia rotundiventralis'' is a species of cichlid endemic to the African Great Lake Lake Tanganyika where it occurs in the southern and southeastern parts of the lake. It is found in shallow areas with a mainly sandy substrate interspersed with rocks. It forms schools which can number more than one thousand individuals. It feeds exclusively on plankton by picking out individual food items with their protractile mouths. Both sexes mouthbrood although up to in length, the fry are mouthbrooded only by the female. If the young are separated from their parents they can be found among other cichlid broods e.g. ''Lepidiolamprologus elongatus ''Lepidiolamprologus elongatus'' is a species of cichlid endemic to Lake Tanganyika where it prefers rocky areas.

Tetsumi Takahashi
(23 February 1935 – 12 November 1990) was a Japanese avant-garde artist whose multidisciplinary practice included painting, performance, installation and sculpture. Associated with the Anti-Art (''Han-geijutsu'') movement in Japan in the late 1950s and early 1960s, Kudо̄'s provocative art was nourished by lifelong interests in science, sport and everyday objects. His work often presents a radically transformed and grotesque vision of the human body, calling into question its desires and its limits, as well as its future and origins. Never having officially identified with any one group or movement throughout his international career, the artist's body of work evades art historical classification. Biography Early life and education Kudо̄ was born in 1935 in Osaka, Japan to two artist parents, both art teachers. His father, painter Kudо̄ Masayoshi, passed away when Kudō was ten.Doryun Chung (ed.), ''Tetsumi Kudo: Garden of Metamorphosis'', exh. cat., Minneapolis, ...

Kazuhiro Nakaya
is a Japanese marine scientist and ichthyologist. He graduated from Hokkaido University with a BA in 1968 and with a PhD in 1972. He is professor of Marine Environment and Resources at the Marine Laboratory for Biodiversity. He specializes in taxonomy and evolution of sharks, rays, chimaeras, and Lake Tanganyikan fish. He is the author of many articles and books on sharks and fish. In 1995 he was put in charge of dissecting and preparing the 7th specimen of the very rare megamouth shark.

Cichlid
Cichlids are fish from the 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 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 scientifically described, making it one of the largest vertebrate families. 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. 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 aquariu ...

African Great Lake
The African Great Lakes ( sw, Maziwa Makuu; rw, Ibiyaga bigari) are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. They include Lake Victoria, the second-largest fresh water lake in the world by area, Lake Tanganyika, the world's second-largest freshwater lake by volume and depth, and Lake Malawi, the world's eighth-largest fresh water lake by area. Collectively, they contain 31,000 km3 (7400 cu mi) of water, which is more than either Lake Baikal or the North American Great Lakes. This total constitutes about 25% of the planet's unfrozen surface fresh water. The large rift lakes of Africa are the ancient home of great biodiversity, and 10% of the world's fish species live in this region. Riparian countries in the African Great Lakes region include: Burundi, the Democratic Republic of the Congo, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Zambia, Tanzania, and Uganda.

Lake Tanganyika
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 among 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. Etymology "Tanganika" was the name of the lake that Henry Morton Stanley encountered when he was at Ujiji in 1876. The name first originated from the Bembe language when they arrived in South Kivu around the 7th century, they discovered the lake and started calling it “êtanga ‘ya’ni’â” which means “a big river” in their Bantu language. Stanley found also other names for the lake among different ethnic groups, like the Kimana, the Yemba and the Msaga. An alt ...

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

Mouthbrooding
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Perissodus Microlepis
''Perissodus microlepis'' is a species of cichlid endemic to Lake Tanganyika. This species reaches a length of TL. This species can also be found in the aquarium trade. It is a scale-eating 'parasite' on other fish species. It occurs in two distinct morphological forms. One morph has mouth parts twisted to the left, enabling it to eat scales off its victim's right flank. In contrast, the other morph, whose mouth is twisted to the right, eats scales off its victim's left flank. The relative abundance of the two morphs in populations is regulated by frequency-dependent selection Frequency-dependent selection is an evolutionary process by which the fitness (biology), fitness of a phenotype or genotype depends on the phenotype or genotype composition of a given population. * In positive frequency-dependent selection, the fit ....Stewart, T.
