How long would it probably take for a starfish with a 5 inch long leg to regrow half of its leg?

Dear multiple man:

From my experiences with sea stars, I've found that the length of time for regeneration varies quite a bit depending on species, however, to regrow half of its leg, (assuming the amputation doesn't kill the animal), I would guess it would take at least 1 year for the average sea star with a 5 inch long leg. The regenerating leg probably won't ever look quite as long as the other legs (more properly called "rays"). I hope this helps! Thanks for asking!
