Thanks Jim. Zackenkrone Radertierchen is German and maybe translate as "prong crown". I somehow like these vernacular names since I usually cannot remember the latin names ;)

Great catch
I have yet to see one of them - is your sample from a pond or a river?

Thanks 75RR. It is from a "Koi" pond where I took a sample of algea. Seem they have a stable population there. When I first started microscopie in 2015, I also find some of them.

Still the same pond...the rotifiers genus Collotheca are always impressive to watch because of their size and the huge crown funnel with its long eyelashes.
Hope you like also the fotos:

Thank you Don, Luis and 75RR for your nice comments.

Don, I have used DIC (video with old Zeiss and the recent fotos with Olympus BX DIC)

Nice work!

I was expecting just a little more of Satie and that Rotifer. Nice combination.
