CT_ Posted August 27, 2021 Share Posted August 27, 2021 (edited) I had to max out my microscope (3x*10x so not much) and the digital zoom to get this photo but these little guys are swimming around in my moss jar. They're maybe 400um long. shaped like a football mated with a clam and where they split legs come out and are used to swim around. To the upper right you can see a slightly smaller and flatter water flea thats out of focus but decided to show up for the photo shoot.

Guppysnail Posted August 27, 2021 Share Posted August 27, 2021 (edited) The size make me think of paramecium the legs a protozoan with flagella. Edited August 27, 2021 by Guppysnail Link to comment Share on other sites More sharing options...
CT_ Posted August 27, 2021 Author Share Posted August 27, 2021 It's definitely got a shell and I'm pretty sure its some multicellular animal Link to comment Share on other sites More sharing options...
