Sampling date 11/2012. Scale bars indicate 10 µm.

Two images. The specimen was grown on a slide placed in water.

First:

Top view showing nucleus and a contractile vacuole.

Second:

Optical longitudinal section through the
tentacles (arrows), which cuts into their bases (inset, arrowheads). This reveals two layers of the tentacles:
– the outer pellicle layer that forms the tentacle shaft and
– an inner ring-like structure that comes from microtubules.
For details on the structure of the tentacles of the suctoria, see Hausmann, K., Hülsmann, N., & Radek, R. (2003). Protistology. p 231.
