The movement of the starfish Starfish is an animal does not have a solid surface on the outside of the spine, but does not adhere to the muscles. Starfish movement by water (the water vascular system) the structure of the system consists of a water pipe.
Recycling the mad Wright (madreporite) is the inlet grille is right behind a starfish.
Pipe rings (ring canal) is a pipe around the mouth. Connect to a small tube called the stone canal, it tube from the registry a mad Wright.
Guidance pipe RADIUS (radial canal) is a pipe that is separated from the water pipe along the radial ring.
Thiofit (tube feet) is a structure that resembles a small pipe. There are a lot of the bottom of the trunk on top of the inflation bulb fit looks a thio. Called the maphu Villa (ampulla) thio fit each have.
A small pipe. Connection to pipe horizontal illumination.
Mobile mechanism of a starfish with a pipe system. Occurs when the water flows into the water way. Recycling the past pipe come right into the ring radial and vertical pipes have an maphu Villa. When muscular contraction at the water-pressure maphu Villa into a fit, stretch fit make thio thio long out to tap the floor below. At the same time, the valve will close within the maphu Villa to prevent water flowing back out to the side pipes. After that, the muscular contraction of the thio fit. Make.
There are shorter, so size fit thio push water back into action again at po maphu Villa. Stretching and shrinking of thiofit multiple causes-voltage until the Starfish can move. In addition, at the end of the other side of the suction plate fit like thio (sucker) acting on the adhesion to the substrate while the starfish is moving help moving.
