Amoeba Polychaos dubium

[Olympusman]

What I had been identifying as Amoeba proteus appears to actually be Amoeba Polychaos dubium. The Wikipedia article at http://en.wikipedia.org/wiki/Polychaos_dubium is quite interesting.
These new shots are 9 images stacked in Zerene Stacker PMAX. Shot with an Olympus A 20X PPL 040 160.17. The relief in the images is caused by shifting a darkfield stop under the condenser slightly off-center.

You do very nice pictuere but I don't no why they are so noise.To remove the noise you can simple use the Topaz De Noise plugin for Photoshop here is the result with your images.
Best regards

Have a look here: http://www.arcella.nl/polychaos
To be sure you have to look for the nucleus and see how it looks like!

I'll give the Topaz plug-in a try. I also think I might be picking up some optical background clutter from my substage condenser. I'm going to try lowering it so it is more out of focus beneath the slide.
Glad to see you tuned in Ferry. We all know you are to go to guy for amoeboids.
I'm pursuing these daily in hope of finding one in division. I noticed something intersting about the environment they live in -- there are absolutely no Micrasterias and a very few Closterium. There as always, many tests from Difflugia, some of them occupied.

I have in all those years never seen a dividing naked amoeba, and I've seen huge numbers! You're always to late, unless you should follow one for hours or days
You can find amoebae everywhere where water is... I find my large amoebae mostly in waters with Micrasterias
If you have any questions, please ask!
