How many radial canals does the starfish have?
The radial canals carry water to the ampullae and provide suction to the tube feet.
What is the function of the ring canals on a starfish?
The ring canals in a starfish are part of its water vascular system, which is crucial for locomotion, feeding, and gas exchange. These canals circulate seawater throughout the starfish's body, allowing it to control the hydraulic pressure in its tube feet. By contracting and relaxing muscles, the starfish can extend or retract its tube feet, enabling movement and the ability to grasp and manipulate objects. Overall, the ring canals play a vital role in the starfish's ability to interact with its environment.
What do the semi-circular canals do?

Why are starfish hard to pull of rocks?
Echinoderms (which include starfish) have a water vascular system associated with movement in some species and feeding in others. Water is pumped around the system through the ring canal, lateral canals, radial canals, ampulla, podium and to the sucker feet. This water vascular system has a vacuum effect allowing the starfish to suction its many feet to the substrate and release them at its own will.
