My planaria are regenerating fast I had a head and it is currently a head with a body I started off with 1 whole planaria and now I have 3 whole ones. I am going to try to cut them again and see what happens I will try to get a two headed planaria. I think that the two headed planaria will work if I cut the head down the middle. If the two headed planaria wroks I hop to make an 4 headed planria and see what happens.
