Do worms regenerate?
An earthworm can regenerate its head and its tail. An example is, if you go dig a earthworm out from the ground and chop it in half then its head will grow a new tail and the tail will grow a new head. Eventually there would be two earthworms. If you cut an earthworm into four piece's then after a few weeks or even months there would be four earthworms. So if you think that if you cut an earthworm you are killing it you are wrong. But if you cut an earthworm into too many piece's, example twelve then you will kill the worm, and after that there is no way to bring it back to life.
How do animals reproduce by fragmentation?
Animals like sponges and coral colonies naturally fragment and reproduce. Many species of annelids and flat worms reproduce by this method. The animal splits and the two parts remake lost organs and tissues. The splitting is not preceded by the development of the tissues to be lost. Prior to splitting, the animal may develop furrows at the zone of splitting. The headless fragment has to regenerate a complete head.
