Under the Microscope...

Here is a video of microorganisms in a dirty science mixture. There are a couple microorganisms in the mixture: Parmecium and Rotifers.

 

Paramecium move with the assistance of small hairs called cilia. Cilia projects from all sides of their bodies. The single-celled organisms use these hairs like oars, beating them against the water to move around in pursuit of food and to avoid predators. A paramecium cell ranges from about 50 to 350 µm in length.

 

Rotifers move around by spinning their cilia in a wheel motion and swimming through the ocean.  Rotifers are 0.1–0.5 mm long (although their size can range from 50 μm to over 2 millimeters).
