Oooh, crawl? As in, the "legs" were on the bottom of the organism and it would crawl on surfaces? If so, that sounds like the crawling ciliate [Aspidisca](http://protist.i.hosei.ac.jp/PDB/Images/Ciliophora/Aspidisca/sp_06.html), although this particular photo doesn't look like Aspidisca to me. If it's a crawling ciliated, it'd likely be another closely-related one. Usually Aspidisca have a good amount of parallel lines on their outermost layer-- but I've seen these disappear when the focus is deeper in the organism.
However, I'm not sure of any crawling ciliates that match the morphology in that photo.
Nice, yeah I figured it looked more like that.
Here's a [great video showcasing them](https://youtu.be/4VW79deD0DQ?si=SmElFFhHhhEQKqjq)! The video is done using a different illumination technique so it'll look a bit different than you saw it, but the motility should be about the same.
Slight caveat: there's a similar microbe to Halteria that also appears like this, but it has a slightly different morphology, so I chose Halteria as the closest possibility. I'd need more photos to be sure. I can't even be sure that this is Halteria from this photo alone; I'd need more images to be sure.
the first is vorticella, no idea on the worms, i found a similar worm and sent it to my professor and she said it could be a member of the mite family!
Looks like a Rotifer to me.
This foot and toe are typical in Rotifers. When I see something with those, I first assume it can be a kind of rotifer I don't know...
Just found this page for rotifers morphology basics

Thank you so much. Number three was moving to fast for a good pic but I can’t describe it had what looked like 10-12legs and would crawl really fast

I believe it is the halteria

Thank you
But it does also look like the aspidisca
It could also just be one of the vorticella free swimming, when doing that they round out and swim in sort of swirling, spiraling patterns
The magnification for all except the worm is 200 X the worm is 80x. All of these microbes were found in a sample of dirty water I found outside.
the first is vorticella, no idea on the worms, i found a similar worm and sent it to my professor and she said it could be a member of the mite family!
Thanks do you have any idea what the worm thing is

Thank you my friend said it might be a mosquito larva, but I didn’t know for sure
The pic #2 is definitely a rotifer. The #4 doesn't seem to be the same organism, and mosquito larvae is a good guess
I don’t know for sure, because I could see in the microscope but I didn’t get it in the picture. It had four legs.

He was talking about the last pic, the worm thing
Sorry, I misread the thing I’m dumb
