Detailed explanation-1: -Water vascular system is a unique characteristic of echinoderms. It helps in locomotion, the capture of food and respiration.

Detailed explanation-2: -The water vascular system is a hydraulic system used by echinoderms, such as sea stars and sea urchins, for locomotion, food and waste transportation, and respiration.

Detailed explanation-3: -An echinoderm moves by using many tube feet. Tube feet are small, delicate projections attached along the side of a water-filled tube called a radial canal. Figure 3.85 shows some examples of echinoderm tube feet. Tube feet extend through the small holes in the skeleton to the outside.

Detailed explanation-4: -Echinoderms have a characteristic coelomic water vascular system.

Detailed explanation-5: -Water vascular system is a characteristic feature of the phylum, Echinodermata. It consists of an array of radiating channels, tube feet, and madreporite. The water vascular system helps in locomotion, food capturing, and respiration.
