A starfish has many identifying features. It is a small disc with five arms. The body is very flexible with groups of papulae. It has spines on the upper surface in one or more longitudinal rows. In oblique rows are the ventro-lateral spines just outside the adambulacrais.
Some starfish can shed an arm and grow a new one later if a predator has caught an arm in its mouth.Some, but very few,can grow an entire body from a single ray.
At the end of each arm or ray on a starfish, there is a structure known as the tube foot, which is part of the starfish's water vascular system. These tube feet are used for locomotion, feeding, and gripping surfaces. Additionally, there are sensory organs called eyespots located at the tips of each arm, allowing the starfish to detect light and dark. Together, these features help the starfish navigate its environment and interact with its surroundings.

vascular system requires water in order to survive
Starfish are most recognized for having five arms, as most species of it do. However, they also have five canals on the underside of each of the arms which enable them to feed themselves and move.
A starfish becomes a fossil through a process called fossilization, which typically begins when the starfish dies and its soft tissues decompose. If the starfish is quickly buried by sediment, such as mud or sand, in a suitable environment, the hard parts, like its calcareous plates, can be preserved. Over time, minerals seep into the remains, replacing organic material and creating a rock-like structure that retains the starfish's shape and features. This process can take thousands to millions of years, resulting in a fossil that can be studied by paleontologists.
Yes they can
Sure, starfish larvae are planktonic. Adult starfish are not.
Sharks, fish and manta rays are predators of the starfish. Larger starfish also prey on and attack smaller starfish.
