Question

Quizplus · Accepted Answer

The water-vascular system is unique to echinoderms and is responsible for inflating the tube feet, which are used for various functions including locomotion, capturing prey, and gas exchange. The coelom, tubular gut, hydrostatic skeleton, and hemocoel are not unique to echinoderms and do not play a direct role in inflating the tube feet.
