If so, any hint about the species?

Notice the pentagonal-hexagonal fields of the pellicle.

Thank you very much!

Re: Is this Ophryoglena?
Yes, it is almost certainly Ophyroglena. I didn't see the mouth (a very distinctive feature of the genus), but the overall appearance of the thing, and its slow, rotating movement, are typical. They are tissue-eaters (histophages), and this one has been feeding well. It is very plump, and full of food. The polygonal structures we see are not in the pellicle, but in the closely-packed, envacuolated contents of the cytoplasm (like soap bubbles, they can become somewhat polygonal when pressed together). I don't see any features that would help identify a species.
Re: Is this Ophryoglena?
This is what I was afraid of. I knew that it would be impossible to determine this ciliate beyond gender but I had to try. Thanks again, Bruce, the information you provided about polygonal fields is very interesting.
