How many Number of arms and what shape of arms do asteroidea have?

Answer 1

Asteroidea, commonly known as sea stars or starfish, typically have five arms, but some species can have more, ranging from 5 to 40 arms. The arms are generally radiating from a central disc and have a distinct star-like shape. The structure allows them to move efficiently and capture prey, and their arms are equipped with tube feet for locomotion and feeding.
