Euglena deses is a photosynthetic euglenoid flagellate in the family Euglenaceae, distinguished by its elongate to cylindrical cell body that undergoes pronounced euglenoid movement (metaboly). It inhabits nutrient-rich freshwater habitats, including puddles, ditches, and the surface of damp soil, often forming green biofilms. Its single emergent flagellum propels it toward light to optimize photosynthesis.
