“Like all cichlids, oscars possess teeth not only in their jaws but a set of pharyngeal teeth as well. Teeth in the jaws are small and used for grasping while those in the throat (the pharyngeal teeth) manipulate and process prey items.The type and arrangement of teeth on the pharyngeal jaw plates are one of many important characters useful to systematists in deciphering the evolutionary relationships of cichlids and much study on this important feature has been published.”
