I am thinking that there was not enough detail in the video to allow for a definitive identification. Bruce Taylor said he thought it was,""some kind of haptorid." The Micscape contributor on protists, Richard Howey, said, "I'm afraid I won't be much help on this one; it's is indeed an odd organism....

Nice images, seb!

I watched Amphileptus for hours and haven't seen it eat anything. I really enjoyed your video as it is the first time I see the way it eats. Thanks. I had never seen it eat until recently when my samples happen to have lots of Vorticella. I think that's the secret, there has to be lots of Vorticell...

Is there no evidence of flagella? No, I did not see any flagella on either of the two organisms I observed. Bruce Taylor said that it is some type of Haptorid, but beyond that he wasn't sure. I can't convince myself that it's a Lacrymaria because of the body shape and the ameoboid-like movement you...

Thanks to all for commenting.

My guess is a "shape-shifting" amoeba.. It just has the amoeba look to me..

Yep, it has an Amoeba look to me as well. But it also has a Lacrymaria look. A Lacrymeba?

Look for all the world like an amoeba doing a very credible impersonation of a lacrymaria. Exactly! Thus my puzzlement. I'm guessing that it IS Lacrymaria, just not Lacrymaria olor. There are several species of Lacrymaria, so maybe it's one of them? I'll post on this thread if I learn anything defi...

Reminds me of Lacrymaria, but I've never seen this Amoeba-like movement in Lacrymaria. Also, never saw the extreme neck extension characteristic of Lacrymaria with this organism.

Clear and clean with nice detail. And a good shot of the valve closing and opening.

Nice photos, Jim. I have seen that first organism but had never ID'ed it. Thanks.

I would also vote for adding more water for a more uplifting story, though I understand it is not always possible. To be totally transparent, I had the phrase, "the fragility of life" in my mind and wanted to use it in the video. Ending the video with that phrase seemed too negative to me so I thre...

Bill, I'm not critiquing you or your videos. They are very interesting, and please continue to post them! I'm just saying that you could have added more water and maybe the egg would had an opportunity to hatch, resulting in more uplifting story (but I have no idea what the expected time for a roti...

Interesting video. Why didn't you add water to stop crushing of the egg? I also think that methylcellulose (suggested many times on this forum) helps to prevent crushing by slowing evaporation and raising viscosity. About tardigrades. I keep reading (in popular press) how tough they are, but I'm sk...

Thanks BillT and Francisco!

An excellent video, Francisco! Very clear and detailed. I always watch when I see a cell about to complete a division. By the way, I put a link to a video of yours (Thuricola) on the Facebook Amateur Microscopy forum today in a thread about this organism. Hope you don't mind.

Very nice pics! It seems to me that those alga cells must have something to do with reproduction.

Nice video, Francisco. I have not seen this organism in my samples, so now I have another critter to look for.

Very nice, seb! I like the Rheinberg illumination.

This is one of those sessile rotifers that attaches itself to a spot and stays there for life. Here's a link: http://www.micrographia.com/specbiol/ro ... ss0100.htm

Nice video, Francisco. That's one of my favorite pond water creatures.

Thanks seb and Francisco!

Very nice images!

Nice photo!

Sure looks like division to me. Sometimes I try to follow this until the division completes but it can take quite a while. Sorry, but I don't have a clue about the ID. There is a small group of protists and rotifers that I've learned to ID at the genus level, but not much beyond that.

JimT wrote:Really fantastic video. As you said when I asked about them in early August,

Isn't that always the way? You see your first one and then they pop up every where.

Now they even show up on videos

Yep, those Testudinella rotifers are everywhere! Thanks, JimT.

And thank you for watching and commenting.

Nice images, billporter...thanks. I Have images from our Canada/US St.Lawrence River..I sense the very same species..and similar magnification of image capture. I enjoy the music you imbue a lot of your flicks with, billporter. This time I was certain in the brief start the the music was: "Only Liv...
