Colacium vesiculosum, a sessile euglenoid flagellate
Colacium vesiculosum, epibiontic on limnic Crustaceans or rotifers like Keratella or Polyarthra, size of the cells about 20µ.
Colacium vesiculosum, crop of the above image. Red arrowheads: spiral-shaped pellicula; blue arrowheads: pyrenoids.
Colacium vesiculosum, during the mobile phase the cells have a flagellum which is reduced when the transition to the sessile form happens. The sessile forms of C. vesiculosum have a stalk of gelatinous consistency. The specimen in this image still had a flagellum which could be recognized by the movement (yellow arrowheads).
