Yes, most starfish can regrow an arm (also known as a ray) if it is lost. However, a single arm will not grow into a new starfish. From what I have learned, as long as a part of the central point of the sea star still attached, the starfish can completely regrow. So, it is also possible for 2 halves to grow into 2 new starfish.

Starfish will shed their legs as a defense against predators. It will give up a leg in order to get away. A starfish will grow a new leg to replace one that has been lost.
