I should be able to identify the larger creature, maybe an isopod, but I can't. Is 0045 some kind of worm? I am not sure of the scale.

The ciliate and bacteria sequence was very interesting.

Thanks for the images and videos!

I wasn't sure what to expect for pods. I didn't find any alive. Lots of ostrocod shells however. They must stay in the top couple inches. I did expect a lot more nematode worms but only found one alive.

Seems like by about 3" down in at least a deeper sand bed and at least in that sample bacteria really starts to reign. Lots of detritus was expected as I do not vacuum or clean the sand bed myself.

Wasn't nearly as many ciliates as I expected either. Only found a few and that one at the end I wonder if the bacteria was the root cause of death or just a symptom. They quickly started to disperse soon after movement stopped.

0045 was the only really healthy cyanobacteria strain I found. Only saw a few others and as seen in another pucture/video were quite clear.

The pictures and video of the ciliate were very interesting. I assume that it was the same one? The yellow was the bacteria, I think?

As you can tell from my question about 0045, I clearly can't identify much.

Questions are always good. The pictures and video are the same. 20 and 40x objectives were used. I first saw it and noticed it had an odd "coating" of some kind. The darkfield really made that stand out as the greenish yellow specks. After the ciliate stopped moving is when I realized it was bacteria as they started drifting off.
