.... is that what that is?! Using the Google-search engine
one obtains hundreds of websites concerning cryptbiosis
(aka anhydrobiosis) in microscopic animals... however I kept
running across some obscure ichthyology syndrome with the
same name... huh!

GH: This may be an investigation of cryptobiosis in "spores".

I've read most of that.

comparatively little high-tech modern research has been done
on the subject.
