In some cases freezing isn't the solution - but one must try to see what
happens. I had some shells cracked the same way - some bivalves with
lamellae, some landnails and the worse was two Pleurotomaria... their top
just came off!
When I travel I use alcohol which is the easiest way. Sometimes it is not so
good to use it in small Marginellas or any other transparent shell since you
don't want any animal left inside.
The problem is that in some Countries you don't find alcohol to use. The
solution is...Vodka, aguardiente, or similar spirit drink. I had to use
Aguardiente in Ecuador since I could not find alcohol. Of course the hotel's
maid were looking weird at us every time she had to clean the room and had
to pick several empty bottles....
