Locomotion. In the sea star, water enters the system through a sieve plate. Eventually it is pumped into many tube feet, expanding them. When the foot touches a surface, the center withdraws, producing suction that causes the foot to adhere to the surface. By alternating the expansion and contraction of it's many tube feet, a sea star moves slowly along.
