Another fine ciliate you got me watching, Francisco!
Have you tried slowing them down with some carboxymethyl cellulose or similar?

Hello.
Thanks for your comment.
I have not used products to slow down movement but I want to give it a try. Do they alter the "natural" shape of microorganisms?

I never have either! I don't think they affect morphology - they just thicken the medium. A bit like cooking! You can find references online. Also on YouTube e.g. https://www.youtube.com/watch?v=vowfgDu8Fz4

A very nice, clear video! I can see why you're thinking of Plagiopyla, but the angle and shape of the oral cleft, and the position of the contractile vacuole, mark this as a hymenostome, and most likely Colpidium colpoda. See page 48, here: http://www.wfoissner.at/data_prot/foiss ... _klein.pdf

Thanks Bruce for the correct identification.
