Sample of scum from the turtle pond. Sample obtained from BBB Lily Pad pond, 4/8/19 @ 6:50 pm by sticking falcon tube into pond.

Domain: Eukarya. I can see a membrane-bound nucleus. 140x magnification. Organism is about 3 micrometers.

What exactly are the organisms? We can use a better (real) microscope to look at the sample to determine this.
