The cichlids are a large group of fish known for their ability to rapidly adapt, diverge and speciate in response to environmental changes as they did in the East African lakes when presented with a new range of potential ecological niches to fill.
In this paper a team led by scientists at the American Museum of Natural History, the City University of New York, and Fordham University, have shown that rock-dwelling cichlids of the genus Teleogramma are diversifying in a very sort stretch near the mouth of the Congo River in Africa. The final 200-mile stretch of the Congo River is exceptional in depth, speed, and turbulence, forming the world’s most extreme rapids.
