Starfish, or sea stars, float due to their unique anatomy, which includes a water vascular system that helps manage buoyancy. They have a central disc and arms filled with fluid that can adjust their internal pressure, allowing them to maintain stability in the water. Additionally, their lightweight, calcified structure and the presence of gas-filled spaces in their tissues contribute to their ability to float. However, starfish are generally more adept at crawling along the ocean floor than floating freely.
The buoyant force of the starfish is greater than the force of gravity. This is due to the shape and area of the starfish. It is all physics!

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.
there are cusion starfish, reef starfish, spiny starfish and fire brick starfish in new zealand.
It is called toilet water.
Yes they can
Sure, starfish larvae are planktonic. Adult starfish are not.
