The building blocks of starfish, or sea stars, include specialized cells that form their unique structures. They possess a central disc from which radiate multiple arms, typically five or more, each containing a network of tissues, muscles, and a water vascular system. This system facilitates movement and feeding through tube feet, which are controlled by hydraulic pressure. Additionally, their bodies are supported by a calcareous endoskeleton made of ossicles, providing structural integrity and protection.
