An unusual Albinaria

When land snails become dormant attached to vertical surfaces, they almost always point the apexes of their shells downward. Every now and then, however, one may come across a nonconformist snail sleeping on a wall with its apex up. I presented an example of such a snail in this post.

Here is another one.


These snails are Albinaria lerosiensis. I photographed them in Turkey earlier this month. Both snails had become dormant on the side of a limestone rock for the dry Mediterranean summer. The snail on the left was in the normal orientation with its apex down, while the one on the right had its apex up.

The snail on the right had another idiosyncracy: its apex was missing. Such decollated individuals are occasionally seen among individuals with intact shells.

Which, if any, creatures with an exoskeleton can heal their shells if they break? I assume snails can't but what about lobsters or crabs?
