Re: wetland microscopy, harsh temperature swings, hardy communities.

These flatworms are quite muscular..and the light field of the stage sends them off view rapidly, reminds me of chasing eels in a barrel. The ciliate epibonts favor the posterior end of these flatworms.

I notice the multitude of Ostracod carry no epibionts at all, unusual to me for this wetland site in winter. I see the flatworms carry their epibiont ciliates.
