Transitions between biting and suction feeding generated using stochastic character mapping on a phylogeny of 56 Tanganyika and Malawi cichlids. Individual cichlid images are, from top: Placidochromis electra (suction feeder), Labeotropheus trewavasae (biter), Rhamphochromis longiceps (biter), Eretmodus cyanostictus (biter), Trematochromis benthicola (suction feeder), Neolamprologus helianthus (suction feeder), Neolamprologus longior (suction feeder), Chalinochromis brichardi (biter), Lepidiolamprologus lemairii (suction feeder). Each node in this phylogeny is fully supported (posterior probability >0.99). (Online version in colour.)
