Strobilidium cilia motion I

The cilia surrounding the mouth of Strobilidium are always moving. This organism has collected and stored numerous food particles in its body, but seems to want more.

We can’t be sure, but it might be a sign it has started to devide. Stick-like structures are often identified at the rear end of Strobilidium, although whether these structures take part in cell division is not yet known.
