- 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.
A euglenid with a single anterior flagellum, hyaline tail section, and a deeply ribbed pellicle (scales!, see comments) reminiscent of euglenoids Lepocinclis fusca and Phacus monilatus. Metabolic movement was not observed. Link to video https://youtu.be/GlnYtTwJ9YI.
