Andrew,
  I originally meant the question in the sense that Harry answered it:
what is the largest and smallest gastropod, bivalve, etc. in various
regions.  I was not thinking of largest numbers of taxa or species
diversity.  Sorry for the confusion.
  I also realize that some may not consider some organisms as belonging to
a certain continent.  The giant squids may have been caught far enough
from a coast that someone might consider them pelagic or bethnic organisms
and not belonging to a particular continental fauna.  I leave such fine
points up to the person answering the question.

Regards,
Charlie
