Answer 2

Answer:The primary difference between arthropods and echinoderms is their covering. Arthropods have a tough, non-living outer shell called exoskeleton, which protect their soft bodies while echinoderms have living endoskeletons, which develop within the deeper skin or body tissues and act as their protective covering.
