Complete Biofilm Surface

[Don Schaeffer]

Somehow the biofilm itself is not visible. My looped wire which picks up biofilm picked it up for these samples. But it is a lively biome. There is a range or organisms from medium-sized protists to bacteria. I even briefly saw a round protists with stabbing capabilities. There are a lot of small ovular floaters in the sample.
