Question

Quizplus · Accepted Answer

The water vascular system of echinoderms functions in both locomotion and feeding. It is not involved in nutrient distribution like a circulatory system, nor is it analogous to the gastrovascular cavity of flatworms. While it is not organized bilaterally, it does show some bilateral symmetry in its structure.
