Any of y'all know what this fella is?

6 months ago by pebbles to c/microscopy

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.

Have you considered if it could be a bristle worm? I haven't seen them under darkfield, so I'm not very confident at all, but the size is right.

I just looked into that a bit I don't think it is a bristle worm. It seems to have a foot to grab onto stuff with. This foot is really throwing me for a loop. Otherwise I would just think it is a worm of some kind.

Thanks anyways!

Edit: These toes really give me rotifer vibes, but the rest of the fella does not give rotifer vibes.

The feet look really tiny, too tiny to be a water bear? The body is segmented and it looks like a digestive tube, which are all pro water bear signs.

What a mysterious little friend

Yeah the feet don't move like a water bear. I see the resemblance from the top down angles. I'm starting to lean towards it being a larvae of some kind.

This is a picture of a midge fly larvae:

My guy definitely isn't that, but it has the segmented body and foot at the back. So maybe mystery dude is some other insect larvae?
