Wonderful. From a stack?

Yes, from an image stack of 24 photos, using Helicon Focus.

Here is the stack of micrographs the image was derived from

Looks like it escaped from the Burgess Shale:
That's just uphill from you, right?

Re: An intriguing freshwater specimen.
I've seen a bunch of what appear to be the same creature (rotifers?) in water from a pond in Wisconsin. Side profile more or less like that of a streamlined turtle. Any idea of the function of the two "crash bars" in the front?
Is this a fresh, but dead, specimen? Mine moved quickly enough so I couldn't have gotten a sequence of frames to stack (well, especially since I don't have a camera on my microscope yet). Your image has far more detail that what I've seen peering at these things through my microscope.
Thanks for posting this!

I've seen similar as well and also did not get any images, but I think you're right that it's a rotifer.FredH wrote: ↑Thu May 18, 2023 6:28 pmI've seen a bunch of what appear to be the same creature (rotifers?) in water from a pond in Wisconsin.

Re: An intriguing freshwater specimen.
Although bdelloids are the most familiar, rotifers come in a wonderful variety of shapes. This one is Platyias. I imagine the spines on the front and back are to make it just that much harder for something to swallow.
