Sea stars have hundreds of hollow, muscular tube feet filled with fluid. These tube feet function in gas exchange, feeding, and in locomotion.
2 Additional Answers Answer for: how do sea stars move
Starfish move by using a water vascular system. Water enters the starfish through a large pore in its underbody and is pushed into its tube feet. The bottom portion of the tube feet expand and push the starfish forward.
Sea stars move by walking on the bottom of the ocean in the sand. They use tons of little feet in unison to move them across the floor and over rocks.
