The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.

First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.

In this case, when a flatworm is cut in half, we can see the following events happen:

  1. At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.
  2. The ends will not be different if the cut is done accurately, but it may differ slightly.
  3. After several days, the ends will present some deformations and will lose the straight shape caused by the blade.
  4. Deformations are extremely similar and change similarly.
  5. When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.

This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.
