Cut off the head of a three-banded panther worm, and it will grow another — mouth, brain, and all. Cut off its tail, and the same thing happens. Cut it in three pieces, and within eight weeks there’ll be three fully formed worms. Put simply: The three-banded panther worm is one of the greatest of all time when it comes to regeneration, which is why scientists started studying this Tic Tac-sized worm in earnest over the past decade or so to learn exactly how it pulls off such an amazing feat. Such knowledge could eventually lend insights into the possibilities for a similar kind of regeneration process in humans.
