This is a large rotifer so it was necessary to provide a "fly over" view. It was pinned down by the coverglass, making it easier to film. The video starts at the anterior end where the corona and its cilia are found. These cilia sweep food into the mouth of the rotifer, where the ingested food is processed by the mastax. This rotifer is covered by a mucilaginous coating with bacteria. The stomach in the middle of the organism also contains oil droplets. At the posterior end is the forked foot. Many other structures in this complex organism are also visible.

Very nice details, Tim.
I like those fiber-like structures a lot. Was it so calm the whole time?

Hi Javier, glad you liked the video. In this particular case, the rotifer was pinned down a bit by the coverglass but these rotifers generally are attached to some substrate. They are thus easier to photograph/take videos. The other structures that you noticed are the muscle fibers of this critter.
