Sea urchins primarily move using their tube feet, which are part of their water vascular system. These tube feet are extended and retracted to create a gripping motion on surfaces, allowing the sea urchin to crawl along the ocean floor. Additionally, they can use their spines for limited movement and protection, but their primary method of locomotion relies on the coordinated action of their tube feet.
