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.


Commentary by Prof. Yuji Tsukii, Hosei University
It is difficult to determine whether this organism is Strobilidium or Strombidium.

A protuberance on the side of this organism is similar to the one shown in the following video.

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.
