Earthworms have a special ability, if they are cut into two sections, they not only die but over a few days they will turn into perfect numbers of broken pieces.

The reason is that when broken into several sections, the muscle part in the spot is broken immediately while shrinking and forming new cells connecting the wound, a part of the undifferentiated cells in the body quickly goes away. to "reinforcement" , along with new cells to form regenerating germs.

At the same time, the cellular organization in the trachea of ​​the nervous system organs and blood vessels in the worm, through rapid multiplication and division in large amounts in regenerating germs. Shortly after, the first part of the head grow a new head, the tail of a tail grows a new tail, a earthworm has turned into many complete earthworms according to the amount of rupture.

Where earthworms are broken down into many complete worms called "rebirth", in addition to worms, there are also leech species regenerating like that. The lower the animals, the greater the regeneration capacity.
