Cichlid (IMAGE) Georgia Institute of Technology Caption Cichlids are found in freshwater habitats worldwide. Biologist J. Todd Streelman studies the varieties from Lake Malawi in Africa because species possess very similar genomes but drastically different forms, functions and behaviors. Streelman's lab combines study of the ecology, genomics and development of these fishes to understand how organisms evolve diversity. Credit J.
