This is a free-swimming individual, but as it did not appear to have basal cilia, I do not think it was a telotroch. The shape was exactly similar to the adult stalked form.
This individual spent a lot of time facing upwards and moving around in circles and this gave me an opportunity to try and get some plan view shots showing the cilia.

Your english is fine Bernhard. I was thinking the same thing about the nuclei. Everytime I see a vorticella the nucleus is the first thing I look for, why I don't know. I suppose that it is just that it stands out so well in the lorica with its "C" shape and appears sky blue at low magnifications. I have always wondered how it would look from various angles and so that is probably why it is the first thing I look for.
