Paul:
 
Though this is addressed to Paul, the answer to the following question
should be of interest to a number of people on CONCH-L
 
A while ago, you had a most complete listing of what species can be
found where in Cape Cod and environs.  This will appear in Internet HSN
in October.  My wife, after reviewing the issue for errors on my part
asked a simple question.  What do the molluscs who live in the splash
zone on intra tidal areas do when it is freezing in your arctic
conditions?  One would suppose they would freeze solid, expand and break
the shell without some means of protection.
 
It is hard for tropical people such as us to imagine such a rich source
of species as you listed in your area, though we lived most of our pre
middle age lives in the New York/New England area.
