Some Unknown Microbes - Measurements Added

[Mitch640]

I thought I had a nice collection of links to sites with long lists of algae and animals, with pictures, to help me ID the things I find on a slide. But after several hours, I can't positively ID a single one of these, and they are from one slide in just 20 minutes or so. I don't know how you guys do it, other than you've spent a lifetime in the business. Or maybe a photographic memory.

I am still getting my microscope debugged, but just took some shots of my micrometer and added them to these images.

1. This was rather small, not moving at all, and it's a crop of the full frame shot with the 40x. I thought it was a Euglena, but I saw no flagella.


2. This thing was quite large, 40x, although it did not move at all either and had smaller bugs sniffing around it.


3. This I think, is some kind of plant spore. I have found them in my aquarium before, but as yet, have not identified them. 40x and a crop.


4. I think this might be a testate amoeba, although it didn't move either. Not sure why I found so many non movers in this sample, as usually the slide looks like a frat party in full swing.


5. This one was also dead looking. Another testate amoeba shell?

Sorry Mitch but I don't recognize any to give a definitive ID.
The last one could be a Euglypha sp. but I will not be surprised if I am way off.

This was the first time I had seen one of those. I have seen many of the kind that Charles posted awhile back, with the scaled sides and wider mouth, but none quite like this shell.
