The trouble is, we are all fishing in the same pond and I prefer to post something (relatively) new in this forum. Impossible.

But this one was new to me. In the farm land on the other side of the street there were patches of rainwater, on some places more than 20 cm deep. and because there was a lot of rain there was water for more than a month, maybe two. We had friends over with children and the youngest son took a bit of algae. When we examined it at home we found Lacrymaria olor. I had not seen it for a very long time. But the next day it was gone. So I started to collect the water but did not find Lacrymaria anymore. But there were many other interesting organisms, Euglenophytes, ciliates, rotifers, etc.
Last week it started to freeze so the source is now covered with ice and snow. But I am happy that I could collect many organisms so near my house (50 meters).
I have no idea what kind of ciliate this is. I have not found it yet in my books. Does anyone have a suggestion?
Photographed with a Zeiss 25X planapo. My favourite objective because it gives quite o.k. DIC. Better contrast than all my other objectives. Although I still have to enhance the contrast a bit. (old equipment) The pictures are a bit the same. One with slightly darker background.
