Name: Multiple Man
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!
