An inactive flagellate is sitting completely still without moving. One after another, two small ciliates come to the front of the inactive flagellate, and stop as to check on it before they leave. Soon these ciliate return for another visit, and it looks like the two different kinds of organisms are communicating. To our surprise, the flagellate suddenly becomes active, contracting its body and shooting out of our view.
