If a worm is cut in half, will both parts grow back? The answer is "It depends". Worms do have a remarkable capacity to regenerate lost or injured parts, but this capacity is limited. Depending on where the worm was cut, the anterior end may be able to regenerate a new tail. The trail, however, can not regrow a new head.
