Question

Quizplus · Accepted Answer

The water vascular system of echinoderms functions in both locomotion and feeding by using water pressure to power tube feet used for movement and to bring in and filter food particles. It is not involved in circulation of nutrients to body cells, is not bilateral in organization, and does not move water through the animal's body during filter feeding.
