What's the magnification? If that was a rotifer in the first few frames, I think what you are seeing is ciliates. O marina is a lot smaller. Unless I'm wrong, which won't be the first time.

They didn't look like ciliates to me but I can check again. Once I get the cultures ramped up I'm going to experiment with 3 different containers to see if it makes a difference:

What was the magnification on that video?

That's a ciliate in the first few frames, not a rotifer. At least, I think so.

I "think" the magnification was 100X. Andy is correct, the big thing was a ciliate. I thought it was a rotifer at first too but I watched it again and looked closer.

That makes sense. My microscope only goes to 40x, and OM look significantly smaller. At 100x they should be the size we see in your video. False alarm.

Definitely Oxyrrhis. Shape and movement are correct.

Woot! Nice and clean looking; no Euplotes visible. I've seen denser, but that's pretty good.

Thanks, I just took a tiny sample off the top.

I hardly ever see any ciliates in my cultures. Probably has to do with the whole being a bazillion miles from the coast.

I'm also a bazillion miles from the coast, but I get occasional ciliates. This time, I think, from Jim W., not that I'm complaining. He's sent much appreciated cultures, and the ciliates are a bonus, in my opinion. Sometimes I get them from rotifers at the university.

I scrapped the flask and am using the 2 different clear containers and they seem to be working fine. I've been feeding RGC every day, or so, and the cultures are thriving. I strain each container every 3-4 days with a 53m sieve to get the yucky stuff out.
