Lake Malawi contains a greater variety of indigenous species of Cichlid fishes than any other lake in the world. World Wildlife Fund researchers have identified over 500 species to date that are not found anywhere else in the world. That is more than all of the freshwater species found in all the waters of both Europe and North America. The cichlid fishes of Lake Malawi have been crudely lumped into three main groups: Mbuna (pronounced "um-boo-na"), Haplochromines, and Peacocks.
