The class Ophiuroidea consists of marine animals characterized by a central disc-shaped body, surrounded by long, thin and often very mobile arms that allow them to move quickly and feed by capturing food particles. Unlike starfish, ophiuroids do not have tube feet and their arms are equipped with specialized structures for locomotion and feeding.
