After the entire process of fission, the bodywall at the fission site remained a liquid or mucus like consistency for at least two more hours. The following morning, the bodywall had its normal consistency and the wounds at both ends were nearly entirely closed. The fission process took several hours to two days and signs of regeneration appeared two to five weeks after fission.
