It, like the paramecium and blepharisma, is a ciliate (having short hair like extensions).
They are blind and wingless and may be no more than 0.139 mm (139 m) in length (smaller than a single-celled paramecium).
The paramecium is a single-cell organism, so has nothing remotely resembling a brain.
Examples of protists with a pellicle are the euglenoids and the paramecium, a ciliate.
In the late 1950s he conducted an elegant series of experiments in his endeavours to discover what it is that mediates the synchronised movement of the paramecium's cilia.
