Starfish with three regenerating
rays.

Among the amazing abilities of starfish is a remarkable talent for regeneration. A starfish that loses a ray can grow a whole new one, given time. Most species can only regenerate if the central part of the body is intact, but a few species can grow back even from a single ray. Those species, like Linckia, will regenerate several whole starfish from a single starfish that gets torn apart. |
