The eating of scales and the skin surrounding the scales provides protein rich nutrients that may not be available elsewhere in the niche. [71] Fish jaws normally show bilateral symmetry. An exception occurs with the scale-eating cichlid Perissodus microlepis. The jaws of this fish occur in two distinct morphological forms. One morph has its ...
