How a young starfish may differ from the adult starfish?

Young starfish, or larvae, differ significantly from adult starfish in both appearance and lifestyle. While adults exhibit the characteristic radial symmetry and distinct arms, young starfish are often bilaterally symmetrical and may have a more gelatinous, free-swimming form. Additionally, the larvae primarily float in the water column, relying on plankton for nourishment, whereas adults are benthic, feeding on small invertebrates and detritus on the ocean floor. This transition from a pelagic to a benthic lifestyle marks a significant developmental change as they mature.
