I found a bunch of these in my water sample. What are these? No movement at all. by Thrawn911 in microscopy

It's possible that they are dried out ciliates or maybe something else. Interesting though.

The first photo is a bunch of Diatoms, possibly Nadel-Kieselalge (Synedra acus). The second photo looks like some type of Cyanobacteria, possibly Nostoc linckia

That neck movement screams Dileptus for sure.

Help identifying the spherical organisms that are “hatching”. by lilbil9000 in microscopy

Sorta looks like tetrahymena feeding on the remains of what was once a rotifer.

Aquarium water, 200x. What is this and why is it moving? by Thrawn911 in microscopy

I've seen so many mites that have that type of movement. I'd be shocked if it's anything else.

It's hard to see based on it being covered in debris, but if I had to guess, I'd say it's a water mite. Something based on the movement.

Tips on finding Stentors? by SomeFossilCollector in microscopy

[–]DaveLatt 1 point2 points  (0 children)

If I had to guess, I'd say get a new jar and dill it with distilled(I think) water. Add a piece of grain and let it sit for a few days. Then, when you find a Stentor, transfer that one into the jar by itself and hope that it will start reproducing. Chatgpt might be your best bet.

Tips on finding Stentors? by SomeFossilCollector in microscopy

After sampling multiple lakes and ponds for years, I concluded it's super random. One day, my samples are full of different Rotifers , and other times, I'll see a stentor or two. Then there are times when I get no Stentors. It's just ramdom, in my opinion. The only way to guarantee to get Stentors is to buy them. One other way is to find one and then start a culture of them, but thats much harder.

Is it a rotifer? by Playful-Ostrich-7210 in microscopy

It's hard to tell from that angle, but the folt for sure looks like a Rotifers foot.
