In march I got some very sick snails from a father of a little girl, she didn't take for her snails anymore (she kept them in a basket on the balcony without soil, water or food), so he carried 14 snails to my place, otherwise he wanted to put them to the garbage. One of them was a subadult Arch. puylaerti, she didn't grow all the time and the last few weeks the was very inactive and didn't want to eat.

Before I was going to freeze her I wanted to wash her and then....the snail fell out of the shell, it looks like this, I never saw this before:
