It doesn't, really. Starfish are remarkable animals for their strange characteristics, but radial symmetry doesn't have significant benefit to the survival of the animal.
Box starfish has pentaradial symmetry.

Most Echinoderms have radial symmetry. Sea Urchins, Starfish, Sand Dollars, etc.

Animals in the phyla Cnidaria and Echidnodermata (for example starfish and jellyfish) have radial symmetry.

Radial symmetry is a type of symmetry where body parts are arranged around a central point, like the spokes of a wheel. Organisms with radial symmetry, such as starfish and jellyfish, can be divided into equal halves in multiple planes passing through the central axis.
like a crab, is equal on both sides radial symmetry is like a starfish
Bilateral Symmetry - Right down an animal (Worm or fish)Radial Symmetry - Symmetry like a circle (E.g - Starfish)Asymmetrical - No symmetry
the special characteristic of starfish are they have an Exoskeleton and Radial symmetry
