Continuing Search for Protists

[Don Schaeffer]

I have hopes and aspirations that get in the way of objective judgement here. In the mudpuddle are various suspicious-looking objects. I know the bacteria, especially the strings. But those ovular shapes that simply hang in the water and some circular forms that seem to be moving inside are a question. Are any of these organisms? Or are they all just fragments that broke from or jarred loose from a leaf?
