Observed an organism in water sample and amazed to observe such a tiny creature , thanks to Foldscope. Dear Manu Prakash, as suggested by you it may be Rotifer, i sat with the sample again could able to find similar one and recorded its movement in detail. attaching the videos without editing , may be useful to observe their behavior.

I tried to track for more than 3 hrs with time lapse also, it stopped moving and slowly the slide started drying and  dried completely. I am enclosing a screenshot of all videos i recorded. Unable to enclose more than one video, hence enclosing other videos in different posts
