Light microscope footage of Difflugia pyriformis testate amoeba, showing their movement in timelapse. The original capturing time was about 6 min. Testate amoeba are a polyphyletic group of amoeboid protozoans with a shell or test that is unique to that particular species. Difflugia have agglutinated shells composed of mineral particles or diatom frustules, that are assembled on structured or sheet-like organic cement. All species of Difflugia acquire their shell particles from their environment. The Difflugia cells shown here have symbiotic algae genus Chlorella, they appear in clear green colour. The cells shown here have collected very large sand grains for their tests and have a length of about 150 m. They were found in a sphagnum habitat near Cologne, the Wahner Heide. Microscopic contrast method used : Phase contrast. Captured field width : 0, 8mm | |
