Your photo is appears to be missing a stalk like the bug in this photo. These are commonly called stalked ciliates. There are thousand species of stalked ciliates. I took these photos using a phase contrast microscope at 400x magnification. All these are different species of stalked ciliates. The cilia are located at the top and have a stalk which they use to attach, affix, anchor themselves to a substrate to keep from floating away.
@Victor so cool! @CJLavoie
