Extract

All living organisms possess mechanisms for obtaining nutrition. Many invertebrates also possess movable mouthparts capable of capturing prey or particulate food (e.g., polychaetes, cephalopods, arthropods and echinoderms). All living vertebrates have specialized mouthparts, and as far as we know all fossil agnathans had them also, but movable jaws supported by an internal skeleton are absent in living and fossil agnathans.
