Starfish are said to have pentaradial symmetry because their body structure is organized around a central axis and typically exhibits five arms or rays extending from this center. This symmetry allows for a balanced distribution of body parts, facilitating movement and feeding in their marine environments. While some species may have more than five arms, the pentaradial form is the most common and characteristic of the class Asteroidea. This symmetry is an adaptation to their lifestyle, allowing them to interact with their surroundings from multiple directions.
