Third Observation

The third observation took place Wednesday, November 9, at 10:00 a.m. I observed the following organisms:



Actinosphaerium sp., identified from D.J. Patterson's Free-Living Freshwater Protozoa




Chaetogaster sp., identified from Kenneth G. Rainis and Bruce J. Russell's Guide to Microlife



Metopus sp., identified from John Lee's Illustrated Guide to the Protozoa








In the anterior image of Chaetogaster, its mouth opening can be observed.

I observed all of the organisms featured here in photos for ths first time in this third observation. I also got another look at several Euclenis sp. (but am not sure which book served as the identifier for this organisms), which had what appeared to be perhaps a double flagella that looked like a pointed tail. I had previously seen one of these appearing to scour the surface of the tank for food.

It seems that the diversity and sheer number of organisms have decreased at this point, but there are still a good number of organisms thriving.
