It was huge(based on the micro world). The medium collected was soaked moss on side of stream with tap(well water) added. Sample was infested with Rotifers among other microbes. I have a cell phone video of it but not able to load. Photo was extracted from video. Movement seemed to be coming from 2 legs just right behind the head, looked like it was doing the dog paddle but legs was in sync(both moving same direction at same time) and quite fast. I am new to the micro world only had microscope like 3 months. I know it is not a single or multi cell microorganism, many times bigger than a nematoid, just amazing what ya find.
