The type of symmetry exhibited by starfish is known as radial symmetry. This arrangement allows starfish to be divided into multiple identical sections around a central axis, typically exhibiting five arms. Radial symmetry is advantageous for organisms like starfish that are primarily sessile or slow-moving since it enables them to interact with their environment from all directions. It also plays a key role in their feeding mechanisms and locomotion, as it allows for efficient movement and the ability to access food sources.
