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. Flagella can be short. Although it can squirm it is not very actively metabolic. With large numbers of small plastids. This image is of a flattened cell, and it shows from front (left) to back: entrance to flagellar canal, eyespot, light region of the flagellar pocket, link-shaped paramylon grain, smaller paraymyloin grains, plastids and nucleus. The ridges of the pellicle are superimposed. Differential interference contrast.
