Identificaciones de syrza

ID is a wild guess. Slow and shaky movement. At least two seen and posted separately.

Found in small grassy puddle with exposed soil on a rainy day. I stirred up the dirt before collecting a small vial of water. Only set up one slide moving the cover glass to two separate bits of water.

I know next to nothing about microscopic organisms and only recognized rotifers, maybe a diatom or two and I am assuming the very quick moving things I couldn't photograph were paramecia. I didn't photograph everything that caught my eye, mostly because it was tricky getting everything in focus with my phone and also tracking down the quick-moving organisms. I wasn't super organized about keeping track of magnification but I mostly shot at 100x with a few shots at 400x.

Observed on my bike ride home from a talk I gave about iNat for the Coral Gables Farmer's Market. I ended up stopping several times to check oaks for galls and other insects and climbed a few trees. Did end up hitting a few vacant lots too.
