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.

That's awesome.

I'm hopefully close to done with some major work projects that has lasted over 2 years now. Will still have tons of work but it will not be like what I've been through. Another month or so. Hopefully be back to posting more and using the microscope more.

This is truly fascinating! I'm impressed on one hand, and terrified on the other lol. Some of those critters look awfully nasty! But the entire thing is pretty cool.

Oh, just wait for this new creepy crawly that I'm currently uploading. Very cool and scary looking. IF this thread doesn't make you go wash your hands every time you put them in your tank I don't know what else will.

Found this very cool looking Dorvilleidae from a sample I took from my ATS.

Interesting. Do you know the approximate size of the worm?

It was rather large. I could see it as a tiny strand on the slide. I'd say around 1mm to 2mm in length. In a couple videos it was visited by an ostracod and a copepod with eggs which were smaller in comparison. The above picures were 10x and 20x with the picture of the ostracod at 20x.

Okay, 20x isn't all that magnified.

Cell proliferation dynamics and morphological differentiation during regeneration in Dorvillea bermudensis (Polychaeta, Dorvilleidae).

Paulus T1, Müller MC.




"The anterior blastema transforms into the head, while the posterior forms the pygidium and persists as a proliferation zone; four or numerous segments are formed by intercalation between the former anterior or posterior blastema and the amputee. "

That thing was huge. Was fat and happy until I mess it up. I kept checking back on it every 1 hour or so but the slide finally dried out the last time I check on it. From the paper I linked to last night said it would take 16 hours or so for the regeneration process but it was fascinating to watch the start of it.

Video 3 of the play list has the finally split off of the back end .

My ATS is my favorite place to pull samples from. Easy to get to and always something to find.

Found a ostracod full of eggs for the first time and one of them was nearly fully developed another getting there. Very cool. Also, followed around a little peramecium in there stirring up a bunch of coccus bacteria.


little diatom action first.
