Bright field observation using a Wraymer microscope (model BX-3500TL, Osaka, Japan) equipped with a Floyd-2 HDMI ethernet digital camera (Wraymer, Osaka, Japan). The accuracy of the scale bar, which was set according to the guidance of the manual of the software (Spectman) provided for the camera, was confirmed by using a stage micrometer glass slide (1 div. = 10 µm; Wraymer, Osaka, Japan) at each magnification.

- A pond-side water sample (retentate) was taken on 01/06/2024 using a 10µ dip net to enrich for microorganisms. (The shoreline had a layer of ice about 1/4" thick that needed to be breached in order to accommodate the dipnet. The retentate contained a lot of sediment due to the shallow depth and disturbance caused by the net.) Air temp 35F.
Large (≥250µ long when near completely extended), colorless euglenoid. Long anterior flagellum. An amazing contortionist (metabolic motion), see 1-6 sequence image 2 (be sure to enlarge).

Very small heliozoan (~10µ diamter). Actinophrys does have marine members, but I don't know how small they are. Another possibility is Ciliophrys, a small marine actinophrid heliozoan, https://www.arcella.nl/ciliophrys-infusionum/ and https://www.researchgate.net/publication/296882090_Taxonomy_and_Phylogeny_of_Heliozoa_III_Actinophryids.
From one of the main tidal channels of the salt marsh, a water sample was taken on 11/10/2021 using a 10 micron dip net to enrich for microorganisms.
