text: Here a diagram of an asteroid with cutaways to show internal anatomy illustrates the major features, including the mesoderm-derived water vascular system, a hydraulic system that drives the distinctive tube feet used for feeding and locomotion, five radial nerves that run along each arm/ambulacrum linked by a nerve ring, and the mesoderm-derived skeleton.
text: The numerous tube feet of asteroids are used in locomotion; asteroids with suckered feet may use them to exert a continuous pull on the valves of shellfish (e.g., oysters, mussels) until muscles holding the valves tire and open slightly, allowing the asteroid to insert its stomach.
text: The tube feet on the upper surface are often long and filamentous and apparently used for respiration, while the lower tube feet usually have suckers and are utilized in locomotion.
text: The tube feet often have suction cups on their tips and are used for locomotion in most echinoderms; they also function in feeding, respiration, and sensory reception.

text: The mouth of regular echinoids is surrounded by sensory tube feet, and tube feet farther from the mouth are used in locomotion.
