Euglena
Ehrenberg 1838

Genus: Spindle, cylindrical or band-form; pellicle usually marked by longitudinal or spiral striae; some with a thin pellicle highly plastic; stigma usually anterior; chloroplasts discoid, band-form, or fusiform; two paramylum bodies located on either side of nucleus, rod-like to ovoid in shape or numerous and scattered throughout; contractile vacuole near reservoir; cell division longitudinal (Kudo, 1966).
