Brittle stars are echinoderms belonging to the class Ophiuroidea. They have a central disc and long, flexible arms made up of ossicles, which are small calcareous plates that provide support and structure. Their bodies are composed of a soft tissue covering that allows for flexibility and movement. Additionally, their unique anatomy includes a water vascular system that aids in locomotion and feeding.
