Cichlid fishes in lakes of the East African Rift. The lakes in this area are believed to support and sustain about 2, 000 different species of these fish, each with different ecological and morphological characteristics such as body size. These lakes form a fragmented landscape that bio-geographically isolates the different species of cichlid fish from one another, allowing them, and many of the organisms they live with, to evolve separately.
