I see these objects often. Not always in this color (also in grreen) and do not know what it is. It could be some kind of testate amoebe, but I never saw any movement. I hope someone knows.

Re: Frontonia atra
Yes, I used oblique illumination.
@75RR: I made this small pond to attract birds for bird photography. Works fine. And yes, from time to time I see a frog there. I didn't see dragonflies.

Re: Frontonia atra
Yes, it looks like some kind of dance. There were four or five present in the sample and they all made about the same kind of movement. I have seen that in more species.

Re: Frontonia atra
No, but her is one. Its a prefabricated plastic pond. Its really small, about 1.3x1 meter and about 50 cm deep. I made about 4 years ago and never cleaned it. Never added new water. Sometimes it almost dries out and sometimes it splills over.

Frontonia atra
I found this large ciliate in my small pond. Given the shape, the dark color, the place of the CV and the macronucleus and the trichocysts I think it is Frantonia atra. Lenght of this ciliate is around 270 microns.

Re: A thought about size
I like 75rr's notion of just getting used to mm and microns. Yes, A kind of 'notion'or 'feeling' will come with time, or at least we think it will, because we get used to the terminology and develop some king of 'feeling' about it. In astronomy its the contrary: trying to comprehend how large thing...

Hi Don, I saw your video and to me these small creatures look more like flagellates. Sometimes a flagella is visible.

Re: Need Help to ID
I will give it a try. The video has not enough information - at least not for me - to ID to the species level. 1. Rotifer 2. Algae, looks like a volvox species, but I am not sure. 3. Looks like an euglenas species. 4. A flatworm. 5 and 6. Cyclops 7. Ciliate: Paramecium. Not clear which species. 8. T...

Litonotus duplostriatus
My North Sea sample is full of Pleurostomatidae at the moment. When I started observing this sample I only found very few, but now, after about ten days, its the most abundant ciliate of which I see at least 15 in every slide I observe. two days ago I found this nice one. I think it is Litonotus ple...

Very nice technique. Alas, I don't have photoshop. Tried with PaintshopPro, but didn't work.

Two Pleurostomatidae from the North Sea
These two look like Lotonotus, but there are some differences from the Litonotus species I have already seen. I could not find them in the keys I use to identify ciliates. They are relatively small: 50-55 microns. The first one (first video) isn't very stretchy (or does not show it). The second one ...

Re: Comparative sizes of bacteria and ciliate
I observed spirochaetes some time ago. They can be as large as 500 microns (the ones I saw were 3-5 microns) . It is also possible that the bacteriae in your video are actually a chain of smaller bacteriae.
