Interesting Stentor for ID

I found this Stentor in my pond water microorganism aquarium. The undulating rounded ridges along its side were something interesting to me. Is there any way to identify this? Also, at the beginning you'll see a piece of it separate as it gets wrapped around debris. Is this part of its reproduction or was this a damaged portion?
UPDATE: Apparently this is Stentor roeseli, and the strange undulations and cilia structure along the side is part of its asexual reproduction process.

Hi macnmotion, nice video! I have seen the same thing and I didn't know what to make of it at first. It is the formation of a new mouth as part of cell division in Stentor.

Thanks. I love your video, now I wish I had continued observing the Stentor!

Yes, exactly! S. roeselii in an early stage of division (vermiform macronucleus, no cortical pigments).

Amazing videos !
Only a few years ago such work would have been near-impossible.
