Meeting Abstract 95.4  Tuesday, Jan. 6 14:15  Morphological convergence in durophagous Heroine cichlids CLEMMENSEN, S.F.*; HULSEY, C.D.; University of Tennessee sclemmen@vols.utk.edu Trophic divergence in cichlid fish is linked to shifts in pharyngeal jaw morphology. For instance, in the Heroine cichlids of Central America, the ability to crush hard-shelled mollusks is a convergent phenotype with multiple evolutionary origins. […]
