Variation in the diet and feeding morphology of polyphenic Lepomis macrochirus
Abstract:Bluegill Lepomis macrochirus showed variation in their diet and trophic morphology based on habitat. Pelagic L. macrochirus feed almost exclusively on cladocerans; littoral L. macrochirus feed on a variety of benthic invertebrates, molluscs, cladocerans and insects. Fish from the littoral habitat had wider pharyngeal jaws, which probably allowed them to crush gastropods and process benthic invertebrates.
