FISH SPECIES
Discover fish with recorded distributions in Africa, across inland lakes, ancient river systems and coastal waters.
01 / NATURAL HISTORY
African ichthyofauna is famous for the rapid adaptive radiation of Rift Lake cichlids alongside archaic, relic lineages like lungfish and bichirs. These species demonstrate remarkable evolutionary resilience across dramatic tropical dry and wet cycles.
02 / LIFESTYLE
In the Great Rift Valley lakes (Victoria, Tanganyika, and Malawi), hundreds of cichlid species partition microscopic spatial zones—from rock-scraping mbuna to shell-dwelling dwarfs and scale-eating specialists. In contrast, riverine species navigating the Congo and Nile systems endure massive seasonal water level drops, with some surviving dry periods through aestivation or facultative air-breathing.

04 / FIELD NOTES
The Great Lakes of East Africa witnessed explosive evolutionary radiations where a few ancestral species diverged into hundreds of ecologically specialized species in remarkably short geologic time spans.
Certain species, like the African lungfish, can burrow into muddy riverbeds and secrete a protective mucous cocoon to aestivate for months until rains restore the waterway.
