Echinoderms, such as starfish and sea urchins, possess a unique cell structure that includes a hard calcareous endoskeleton made of ossicles, providing support and protection. Their bodies are organized into five radial segments, reflecting their pentamerous symmetry, and are covered by a thin layer of epidermal tissue. Echinoderm cells also contain specialized structures like tube feet, which are part of the water vascular system, enabling movement and feeding. Additionally, they exhibit a decentralized nervous system, lacking a central brain, with nerve rings and radial nerves extending into each arm.
