## Infusoria – Excursus on Success of Sessile, Vortex-forming Organisms

The 1st two slides were basically the same: lots of peritrichs. Unfortunately, I have to say that the infusoria has been quite uninteresting so far. But it kind of makes me wonder why peritrichs are so successful. I may have mentioned regarding a former slide that the peritrichs (namely Vorticella) were doing quite well, along with some rotifers. So there must be something about organisms that attach and suspend themselves to/from substrates that makes them so successful.
