A short video where Rishon tries to track and keep pace with a fast-moving Euglena. This is a genus of single-celled flagellate - a cell or organism with a whip-like appendages called the flagellum. In this video, you can see the Euglena's flagellum is not a 'tail' but is at the front of its body, with the tip of the 'whip' rotating and propelling the cell forward in the water. The flagellum also functions as a sensory 'feeler', being sensitive to chemicals and temperatures outside the cell. Also note the many cigar-shaped diatoms swimming around it. Euglena eat amoebas, parameciums, rotifers and algae such as diatoms. From water samples collected at Kingfisher Pond in Northstowe, Cambridgeshire. |
