Phacus longicauda.Coloured scanning electron micrograph (SEM) of Phacus longicauda. Phacus is a genus of unicellular protists, of the phylum Euglenozoa (also known as Euglenophyta), characterized by its flat, leaf-shaped structure, and rigid cytoskeleton known as a pellicle. These eukaryotes are mostly green in colour, and have a single flagellum that extends the length of their body (not visible here). They are morphologically very flat, rigid, leaf-shaped, and contain many small discoid chloroplasts. Phacus are commonly found in freshwater habitats around the globe and include several hundred species that continue to be discovered to this day. Magnification: x 2000 when printed at 10cm wide.
