You can compare its size with paramecium in this same video.

This is Frontonia. We don't clearly see the mouth or extrusomes (darkfield is pretty, but not great for ciliate identifications), but the shape and behaviour are unmistakable.

Thanks Bruce.


Frontonia was another of my suspects.
But because only darkfield movie was taken and no mouth or extrusomes were visible, it was the origin of my doubts.
The video has some part using oblique illumination in order to find mouth or extrusomes with no luck.

Thanks again
