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
