- A pond-side water sample (retentate) was taken on 10/14/2023 using a 10µ dip net to enrich for microorganisms. Air temp 58F.
Small amoeboid organism. Often fan shape, narrow portion trailing, wide portion leading. The leading edge is transparent. Organellar material is concentrated in the trailing portion. This amoeboid looks very similar to images here https://arcella.nl/vannella-sp/. Photos 2 and 3 are for comparison with a larger, pseudopod-baring amoeboid. For a video, see https://youtu.be/yiZ1RHs2vOI.

- A water sample was taken on 09/03/2023 from pond-edge using a 10µ dip net to enrich for microbes. Air temp. 80°F.
Rotifer with spiny lorica. Dead. Foot not visible though the opening in lorica that accommodates the foot is visible. This specimen looks very much like Plationus patulus as seen here https://www.plingfactory.de/Science/Atlas/KennkartenTiere/Rotifers/01RotEng/source/Plationus%20patulus.html.

- A pond-side water sample was taken on 07/31/2023 using a 10µ dip net to enrich for microbes. Air temp. 75°F.
Euglenoid. Relatively unadorned lorica. Exceptionally long anterior flagellum, the length is best appreciated in the videos. In the 2nd video, I think we are viewing the pore through which the flagellum emerges.

Small flagellate with a probing "nose". My scope could not resolve the critter cleanly, but it was fun to chase, after it swam into my field of view. (The 2nd image shows the small, inconspicuous, shadowy figure as it appeared in the 400x field.) I could only see it for a short interval before I lost the ability to track it. For fabulous images and video of R. nasuta, see the observations posted by iNatters @crseaquist and @zookanthos: https://www.inaturalist.org/observations?verifiable=true&taxon_id=881489&place_id=97394&preferred_place_id=1&locale=en-US.
