Beautifull!!

I use this key http://www.wfoissner.at/data_prot/Foissner_Berger_1996_375-482large.pdf and this one https://apps.who.int/iris/bitstream/handle/10665/40066/16583_eng.pdf;sequence=1 , both downloadable pdf's. And the work of Kahl. Bruce Taylor provided the links to downloadable pdf's of his books some...

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.

Beautifull and sparkling!

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.

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.

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.

Very nice video. I never saw this species before.

Very nice Wes.

Nice video's!

Nice creature. I see them often in my samples. I think it's a copepod nauplius.

Contrasty, colorfull and sharp. Very nice photographs.

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...

I am not sure but it is certainly possible.

Beautifull!!

I once wrote an article about that for a Dutch magazine about astronomy. Very interesting topic.

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

Nice photographs Don. I never saw this species before. How did you find out what is is?

Thanks Bruce. There are always more possibilities then I am aware of when ID-ing. Makes it difficult, but also interesting.

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...

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...

Microscopy and astronomy have always interested me. Astronomy is great but you are at Mother Nature mercy. Not so with microscopy. I retired exactly ten years ago and didn't even miss my work for one minute. I am also an amateur astronomer (and a mountainbiker and a bird watcher/photographer). What...

Interesting project Don.

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

EDIT: maybe I found it.....will try tomorrow.

Beautifull!!

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 ...

Thanks again Bruce.

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.

I found this very nice ciliate (I think it is a ciliate, but I am not sure about that) in my North Sea sample. No clue what (family, genus, species) it is. Never saw something that looks like it in my fresh water samples. Length is about 220 microns.

I found another Euplotes in my North Sea sample. With a 40 micron length it is smaller then the former one (57 microns). This one also has algae in its body, but it looks like at least some are - partly - digested. Between 40 en 44 seconds an algea is being swallowed.
