Cut off this worm’s head, and it will grow back with the same memories

The planarian is just a little, flat worm that lives in dark places, like the bottom of ponds. It has one secret skill, though, and it’s a good one: The planarian is incredibly good at regenerating. It can grow back its tail. It can grow back its head. It can grow back its body from either of those shorn-off bits. If you snip off both its head and tail, one worm can become three worms. And all three may share the same memories.
