Answer

Tube feet.

Download to view full explanation

Urchins use specialized structures called tube feet to filter water into their water vascular system. These tube feet are part of the water vascular system, which is a network of fluid-filled canals and structures that helps in locomotion, feeding, and respiration in echinoderms like sea urchins. The tube feet are thin, elongated structures that extend from the body of the urchin. They have a muscular base called the ampulla, which is connected to the water vascular system. The ampulla can contract and relax, allowing the tube feet to extend or retract. To filter water, the tube feet have a specialized structure called the podium at their tip. The podium has a small opening called the madreporite, which serves as the entrance for water into the water vascular system. The madreporite is a sieve-like structure that filters out debris and prevents large particles from entering the system. When the urchin wants to filter water, it contracts the ampulla, creating a pressure difference that draws water into the tube feet through the madreporite. The water then flows through the canals of the water vascular system, distributing nutrients, oxygen, and waste products throughout the body of the urchin. In summary, urchins use their tube feet, specifically the podium with the madreporite, to filter water into their water vascular system. This system plays a crucial role in various physiological processes, allowing the urchin to survive and thrive in its aquatic environment.
