Meet Moritz. He also has a few buddies, but they are cowards and jump in the water as soon as you approach.
Moritz came to the “Sanctuary” half dead, with a crushed shell. About 30 % of it was smashed and pressed down. Since he was found in a horse enclosure, it’s possible he got stepped on.
The shell was pulled up, cleaned, then glued shut and covered with a sterile cover and fabric. Luckily his lungs were not damaged, which could have happened very easily.
Today the borders of the hole are almost not visible anymore.
