Convergent evolution of hypertrophied lip phenotypes in cichlids fishes. This phenotype has arisen independently in a number of cichlid lineages inhabiting regions ranging from the Nicaraguan Rift Lakes (Amphilophus labiatus), South America (Crenicichla tendybaguassu), Lake Tanganyika (Lobochilotes labiatus), Lake Victoria (Haplochromis chilotes), and Lake Malawi (Cheilochromis euchilus, Eclectochromis ornatus, Placidochromis “Mbenji fatlip”, and Placidochromis milomo). The lineages containing hypertrophied lips from these disparate geographic settings outside of Lake Malawi are well established as phylogenetically independent [79]. However, it is unclear if the hypertrophied lip phenotype has arisen convergently multiple times or alternatively only once within Lake Malawi
