Wolga spinifera rotifer....video

Hello
Small rotifer known - to me -
It has a size of about 60um
It has a curious appendage on the back that I had not seen in other rotifers
I would appreciate your help in identification
Identified with the help of Michel Verolet

Nice find Francisco. Can't help with the ID though, but the foot looks similar to other rotifers I have seen. I've never seen anything like that other pointed thing though.

Hi Mitch
Thanks for your comment
Certainly, the "feet" of the rotifers (those) are similar (they change shape and size). What intrigues me is the small appendage located on the back

I wonder if the "appendage" is actually some other organism, either parasitic or just attached. It seems oddly asymmetric, appearing on just one side of the left/right center of the rotifer.

Hello Rik
Thank you for your interest
The parasite attack is a good choice
I have seen repeatedly infested rotifers and ciliates.
On this occasion, I think without total security, there is no parasite.

After watching the video a second time, I saw the star thing, at the beginning of the video. Did you get more shots of that too?

Hi Mitch
The star of the first I think is Anthophysis vegetans

Wow, that's amazing. I see something new every day. Very nice finds you are getting.

By the way, My new video camera was delivered last week, and it was the wrong one. I had to send it back and am now waiting for another one, which should be here Monday.

Thanks Mitch
The world of microorganisms is fantastic
I am many years in the study and observation of these bodies and still surprising me with each water sample that I put under the microscope

Hola Francisco
It is not easy !If you have found it in the sea , it could be Wolga spinifera.But i don't know this rotifer and it is not easy to see the lorica and the foot opening.
best regards
Michel

Thank you very much for your information Verolet
Indeed, the rotifer was located in salt water
I appreciate the help of an expert in rotifers as Michel Verolet
