This ciliate was found in a pond in Flagstaff, Arizona.

This single-celled organism looks a barrel with slats and strapping.

  • For what reasons do you think this critter needs to move?
  • How does this ciliate's movement compare to other single-celled organisms?
  • How are the cilia (the tiny hair-like fibers) arranged on the organism? Do the cilia in different locations have different functions?
  • Can you find any cycles in the video? How do these cycles compare to other cycles you know about?
  • What is the advantage to this ciliate for having a tube-like shape? How does this critter use its shape?
