Starfish tend to have pentamerous radial symmetry. In other words, the typical starfish has five lines of symmetry throughout their body. Some species have more lines because they have more arms.
Radial symmetry
Bilateral Symmetry - Right down an animal (Worm or fish)Radial Symmetry - Symmetry like a circle (E.g - Starfish)Asymmetrical - No symmetry
a starfish has a rotational symmetry because it rotates back to itself 90 degrees which is 1/4 of a turn.
Pentaradial symmetry is a form of symmetry in which an organism can be divided into five identical parts around a central axis. This type of symmetry is commonly found in echinoderms, such as starfish and sea urchins. Unlike bilateral symmetry, where organisms can be divided into two mirrored halves, pentaradial symmetry allows for multiple orientations in the environment. It plays a crucial role in the ecological adaptability and locomotion of these marine animals.
Pentaradial symmetry is a form of symmetry commonly found in certain marine animals, particularly echinoderms like starfish and sea urchins. It refers to a body plan that can be divided into five equal parts around a central axis. This type of symmetry is distinct from bilateral symmetry, which has a left and right side. Pentaradial symmetry allows these organisms to interact with their environment from multiple directions, enhancing their adaptability in aquatic habitats.

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.
