Oligochaete Inquiry

This worm was collected from Loughborough Lake, north of Kingston, Ontario, Canada.


  • How does this worm move?
  • Can you think of other types of movement that are similar to the one you see here?
  • How does this organism's movement compare to other organisms? to people?
  • 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 organism for having a tubular shape? How does this critter use its shape?
  • What else can you find out about this critter?



olig- comes from the Greek word for "few"

chaete comes from the Greek word for "bristle"

So, oligochaete means an organism with a few bristles.
