I found this nice rotifer in my small pond. I think it could be C. catalina, because its feet are at 90° from its body. Please correct me if I am wrong.
Cephalodella catalina?

Re: Cephalodella catalina?
Nice shot!
But it can not be C. catalina, as this species has a frontal eyespot. Your little friend has a cervical eyespot (at the posterior side of the "brain").
With nearly all Cephalodellas it is impossible to make a sure diagnosis without analyzing the trophi thoroughly. But this would mean to remove all soft tissues chemically to have a good view to all pieces of the trophi. As far as I can see the details in your video, I would guess Cephalodella doryphora Myers, 1934 but I'm far from sure.

Thank you for your clear comment Michael. I will change the name to Cephalodella only.
