lake Baikal and lake Tanganyika

Lake Tanganyika in East Africa. It is similar to Baikal origin (rift) and the size of the basin. Tanganyika length of about 650 km, the width of 40-80 km, an area of 34 thousand square kilometers. The maximum depth in the southern part of 1470 m. In terms of water Tanganyika 2 times less. In it are found hippos, crocodiles.Lake Tanganyika is an African Great Lake. It is estimated to be the second largest freshwater lake in the world by volume, and thesecond deepest, in both cases, after only Lake Baikal in Siberia; it is also the world's longest freshwater lake. The lake is divided among four countries – Tanzania, Democratic Republic of the Congo, Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean.The lake holds at least 250 species of cichlid fish and 75 species of non-cichlid fish(LB-host to 1085 species of plants and 1550 species of animals), most of which live along the shoreline down to a depth of approximately 180 metres (590 ft). The largest biomass of fish, however, is in the pelagic zone (open waters) and is dominated by six species: two species of "Tanganyika sardine" and four species of predatory Lates (related to, but not the same as, the Nile perch that has devastated Lake Victoria cichlids). Almost all (98%) of the Tanganyikan cichlid species are endemic to the lake, and Lake Tanganyika is thus an important biological resource for the study of speciation in evolution. Among the non-cichlid fish, 59% of the species are endemic.
