Starfish exhibit a type of symmetry known as pentameric symmetry, as they typically have five arms arranged around a central disc. This radial symmetry allows them to interact with their environment from multiple directions and aids in their movement, feeding, and reproduction. Unlike bilateral symmetry seen in many animals, the unique structure of starfish contributes to their adaptability in diverse marine habitats. Understanding this form of symmetry is essential in studying their biology, evolution, and ecological roles in ocean ecosystems.
