Hello.
After my last mistake in naming the object on the slide, I decided to approach this issue very carefully.
I found algae on the slide today.
I think this is Tribonema.
That would be from other sources where I found matching pictures.
But that's not the most important thing.
Well, looking in the sample of ciliates (under different magnification) I noticed that inside all segments of these algae something is moving.
For me, this is something very revealing.
And now I have a question: what is moving inside there?
And the second thing.
I used a 100x objective plus immersion oil.
Should the quality of this material be like this because I'm a bit disappointed.
I took a sample from a birdbath in my garden.

Regards
Maciej

I know almost nothing about algae, but that looks like Brownian motion of the tiny particles. No single particle actually goes anyplace, it's just being jostled by random small movements of the molecules around it. The movements should be greater at higher temperatures than at lower ones.

Hello dd5.

I looked at the video as closely as possible on the monitor screen.
The quality is not the best, but as far as I could see, I came to the conclusion that the movements are not ordered.
It's more like a chaotic vibration to me, oscillating about some center of equilibrium.
How to increase the temperature to possibly see the difference in vibrations, I honestly don't know.
Maybe another time.
Anyway, thank you very much for trying to explain this phenomenon.
It's very possible you're right.

Regards
