Cichlidae, a diverse family of fishes, have repeatedly evolved a specialized form of parental care known as mouthbrooding, where parents protect their eggs or fry in their mouth. Some mouthbrooders have evolved larger, elongated heads in order to maximize buccal cavity volume, to allow the largest brood possible, while also maintaining hydrodynamic efficiency and respiratory function. We therefore hypothesized that cichlids with different parental care behavior will also differ morphologically. Based on a previous study in Lake Tanganyikan cichlids we also predicted that rates of shape evolution would be slower in mouthbrooding cichlids. We compared the effect of parental behavior on morphology in 62 African and 99 South American cichlid species. Data on parental care were gathered from FishBase and the literature. We quantified body and head shape variation on preserved specimens using two distinct methods, traditional linear measurements and geometric morphometrics. Phylogenetic comparative methods were used to test for significant differences in head and body shape, disparity, and rates of evolution between species with different parental behavior. Preliminary results opposed our initial predictions, revealing few shape differences among parental care types and showing that the rate of morphological evolution is significantly faster in mouthbrooders, whereas disparity is greater in non-mouthbrooding species.
