Starfish are colorful organisms that live in the ocean. Starfish usually have five rays with each arm along a radius. The arms radiate from the central disk. Starfishes have many limbs and within these limbs are muscles. Those muscles within the limbs help the starfish move around. The tubes on the starfish stick to different objects in the ocean. The tubes start to suction water and it releases water if it wants to get off any object in the ocean. The suction then stops and it does this process over and over again to get around.
