Playing around with my 40x oil objective.
The diatom appears to be Iconella curvula.
The rotifers in this sample are different from most I've seen in other samples. Notice how the cilia freezes. If anyone is a rotifer expert I'd love to know which this is.

Nice videos from a interesting location!
The "rotifer" is a ciliate, as you can see the contractile vacuole.

Of course, thanks for pointing out the contractile vacuole. I've never seen this organism before, whatever it is.

A different video I posted in the ID channel was of a ciliate called stichotricha. It lives in a sleeve. This video was a different organism from the same sample. I'm thinking that this is a stichotricha also, just not sticking out as far.

This is definitely no Stichotricha. has not the typically pointed anterior body.
This looks like a vorticella, opercularia etc they have a kind of discus surrounded with cilia.
It could also be a ciliat living in a house (not visible) Vaginicola, Thuricola etc.

I've seen a million vorticella in my samples, this doesn't come close to any of them. But maybe a different looking type since it's from a new location.
