I found this creature in my North Sea water sample. I has 'toes' (or maybe one toe) like a rotifer, but I cannot find a rotifer species that looks like it (downloaded a marine rotifer key). It has cilii, so it also looks like a ciliate. It could also be some kind of marine ostracod, although it does not look like swimming freshwater ostracods and its also smaller. Length of this creature is about 40 microns.
Ciliate from the North Sea; Orthotrochilia?

Re: Unknown from the North Sea
I have been searching the internet more thouroughly and I think I found it. It is a ciliate, probably Orthotrochilia, maybe O. sinca

That "toe"(podite) is characteristic of dysteriids. Orthotrochilia is one, but there are others...Dysteria, Trochilia, etc. At a glance, this looks more like Dysteria, to me, but I haven't looked at the literature.
