Please help with identification of 3 organisms
Hello everyone!
I was looking at a soil sample that mostly had what looked to be diatoms in it. However, there were three organisms I saw that I hadn't seen before. All of these photos attached below were taken at 400x magnification on a light microscope.
1. This circular one, there were two that I saw. It is dark brown on the outside with a lighter shade of brown on the inside. It was immobile. Here is a picture:
Here's another picture, perhaps it shows the colors better:
(my apologizes for the poor quality of this photo)
From the second photo, it almost looks like a seed, but it was invisible to the naked eye.
2. Here is a second organism, the big circular one that looks like it is crushed:
3. And lastly, this organism that is clear and on top of what looks to be a diatom:
(I apologize for the poor quality of this photo, I wasn't able to use my camera at that moment so I had to use my phone)
Thank you so much!

Re: Please help with identification of 3 organisms
I can't understand the dark ones at all. They don't look like organisms. The bottom looks like two things, one of which may be a rotifer.
Re: Please help with identification of 3 organisms
Thank you, Don! I was suspecting rotifer for the last image (it is on top of the other organism, which I believe is a diatom), yet I do not see many distinct rotifer features and I feel like rotifers are bigger.
The dark circles are definitely a puzzle for me too, they look almost like seeds but would a seed be microscopic? I do not see microbe features on them. Maybe someone will know!

Re: Please help with identification of 3 organisms
At that scale they could be seeds. What magnification did you use?
Re: Please help with identification of 3 organisms
I used 400x magnification. I was looking around the forum and accidentally happened to come across this book that someone linked: https://www.amazon.com/PICTORIAL-ATLAS- ... oks&sr=1-2
If you look at the bottom left of the front cover, there is an image that closely resembles my picture. So perhaps it is a seed!

Re: Please help with identification of 3 organisms
It's a pretty small seed then. It may be a spore.
Re: Please help with identification of 3 organisms
I think we figured out the dark circle, then, although I wonder what species of seed it is. The other two organisms are still a mystery!
Re: Please help with identification of 3 organisms
Hmm, the first three look a lot like a squashed & 'popped' pollen-grain, if they're between about 20-40µ diameter..
