Isotricha intestinalis, a ciliated protozoan, has cilia covering the entire organism. This holotrich protozoan is attracted chemically to plant soluble sugars diffusing from particulate carbohydrates, to which it attaches by means of a granulated organelle on the anterior cell surface, provided soluble protein is present.  The mouth is clearly visible on the anterior end of the organism.  It can be up to 200 micrometers long, making it one of the largest in the rumen.
