Euglena clara is a freshwater euglenoid alga in the family Euglenaceae, bearing a single emergent flagellum and a flexible pellicle allowing metabolic cell shape changes. It is found in eutrophic freshwater habitats including ponds, ditches, and slow streams.

Euglena gracilis is a well-studied unicellular euglenid flagellate found in freshwater environments worldwide. It is mixotrophic, capable of both photosynthesis in light and heterotrophic feeding in darkness, making it highly adaptable to varying light conditions. It is one of the most commonly used model organisms in cell biology and biotechnology research.
