What in the world is an "Ewig's Gastroverm"? It is mentioned as
occuring down to 20,000 feet on a COA page of Extreme Molluscan Facts.
Funny thing is, the only other place i can find it - or "gastroverm"
for that matter - is where i copied this factoid while tuning up a Man
and Mollusc page: http://manandmollusc.net/amazing_facts.html - a bit
too circular for my comfort!!
