Any of y'all know what this fella is?

This is it next to a rotifer.

I'm almost done with a microbes /w music video and I just cannot find any leads on this fella. I'm not so versed in microscopy though. I found this guy in a stream. I got a good amount of soil and moss in the sample. There also happens to be an invasive snail population in that stream called a mud snail.

I could try to upload a video somewhere of it if any of y'all think that would help.
