A major axis of feeding diversity in ray-finned fishes concerns a trade-off between force application and the speed at which the jaw can open and expand. Furthermore, a complex feeding apparatus, consisting of numerous mobile components, has allowed fishes to occupy a variety of trophic niches in aquatic systems. This research seeks to understand the evolution of feeding motions in a diverse assemblage of African cichlids from lakes Malawi and Tanganyika, where species vary in feeding apparatus morphologies and diets. We used geometric morphometrics to compare cranial/jaw shapes with patterns of kinesis produced during suction feeding strikes.
