In the video to the right, two rotifers move through a group of paramecia. This view is at 400 power. The paramecium at the bottom left is approximately 300 microns long.
The rotifers are microscopic multi-cellular animals, not single-celled protists like the paramecia. Can you identify any features of the paramecium?
(The small protist at the top is called euplotes.)
