Descrission:

Euglena deses is a worm like gliding Euglena which rarely swims (ignore the Tetraselmis to the right) is one of a group of worm-like species, either with very short flagella or no emergent flagellum. They rely on gliding to make their way through the substrate. Very metabolic. E. deses is distinguished by the rather similar E. mutabilis by the large numbers of plastids (individual plastids cannot be seen in this micrograph). The red spot is the stigma or eye-spot, the nucleus is the grey zone in the centre of the cell. Phase contrast.
