The vast number of ciliates with their many similarities makes identification difficult, and I'm hardly an expert. I did run across another possibility, which looks similar to Prorodon, Holophrya.

I'm assuming that the wedge shaped area towards the bottom of the picture (around 7 o'clock) is part of the oral zone.

Are these ciliates colored? What I'm assuming is the back half of the critter (the upper part of the picture) seems to be packed with something. Perhaps something with chlorophyl.

There are lots of interesting things to see here.
