Those are about the size of or a bit larger than a freshwater snail
found around here. Sometimes they are called pennywinkles and sometimes
periwinkles. Unlike the New Zealand mud snail these are good news. They
thrive only in the purest springs around here and if they disappear
locals suspect the spring of having gone bad.
Our snails have not yet revealed whether they are metric or not.

As a Bee subscriber, I is quietly proud (as Walt Kelly's Pogo used to say).
So far, I've read no news about any snails being opposed to the use of the
metric system. :)
