Frenemy In A Sentence, An Echinoderm has eyespots which can detect light much like how humans use eye organs to detect light for our ability to see. Instead, the thin walls of their tube feet allow oxygen to diffuse in and wastes to diffuse out. The main difference between Nematoda and Annelida is that Nematoda has a cylindrical body with tapered ends whereas Annelida has a cylindrical body, which is segmented. Body Structure Water-vascular system The water-vascular system is a system of fluid-filled, closed tubes that work together to enable echinoderms to move and get food.
