I think I have found microshells according to this definition but the ones
I have are on the larger end of the scale.  How do you find anything so
small that you have to use enlargement to see it?
 
While cleaning "bubble shells" I have found extremely tiny shells inside
which are so small I have been unable to actually see what they look like.
Guess I need to invest in a magnifying glass?  Anyway, I did find several
of these tiny creatures inside many of the bubbles.  Is there a certain
type that normally will be inside a particular type of shell?
