Need some help on this one

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.

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 definitive.

Hi Bill P.,

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?

"A Lacrymeba?"

Yes!.. Gets my vote!...

Interesting video

Thanks to all for commenting.

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 can see in the video.

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."

So I think it will just have to remain one of those odd but unidentified organisms that we run across from time to time. I was pleased to find that I wasn't the only one who found it to be an "odd organism!"
