What do the pharyngeal jaws of bony fishes do? How is this different from the actions of the anterior jaws (the premaxilla and maxilla)?
What will be an ideal response?
The pharyngeal jaws of some fishes—moray eels, for example—supplement the function of the maxilla and premaxilla by seizing prey and drawing it deeper into the mouth. In other teleosts, such as cichlids, the pharyngeal jaws process food items, biting and crushing them. In contrast, the teeth on the premaxilla and maxilla seize and hold prey but do not process it in preparation for digestion.
