Because the lower pharyngeal jaw of cichlids exists as two separate pieces, the pharyngeal jaws are better able to grasp prey.

Because the cichlid pharyngeal jaws articulate with the braincase, they can be used for biting as well as for moving food to the back of the throat.

The increased musculature of cichlid pharyngeal jaws allows all of these species to be voracious predators of other fishes.

The toothlike projections from the cichlid pharyngeal jaws have evolved to vary in shape and size depending on the particular lake where a species is located.
