Description:

Euglena oxyuris (you-glean-a ox-ee-your-is), is a moderate to large euglena, with a stiff pellicle that has well developed ridges, and often - as we can see here - with a fold in the cell. Flagella can be short. Although it can squirm it is not very actively metabolic. With large numbers of small plastids. Large red eyespot near the anterior (right). Differential interference contrast.
