A ciliate with a stalk

This ciliate, Vorticella, attaches the end of its long stalk to a solid surface. Although the organism is anchored at the base, it feeds by expanding and contracting its stalk to more around within a limited range. We can see the front and side views of Vorticella and the food vacuole which transfers food particles into the body.

Commentary by Prof. Yuji Tsukii, Hosei University
This organism may be Vorticella convallaria, which is one of the most frequently observed of all the Vorticella.
