Paramecium vacuole pore

Post by Charles Krebs »

Thought this might be fun. I was photographing paramecium and when I focused on the surface above a contractile vacuole I could see the pore through which the contents are expelled. Refocusing quickly below the surface, the vacuole itself was clearly seen. So two shots were combined into a small animated gif, providing a quick shift in view from the surface to the interior below it . The diameter of the pore (on the surface) is just about 1.5 micron.

Hi Charles,

very nice anigif, marvellous shot of paramecium surface. Thank you for presenting this rerely seen morphological detail!

Wolfgang... you might also be interested in this older post. It was the first time I really noticed these pores, but it was in P. bursaria, and there were two per vacuole.

(and again, an appreciative thanks to Rik for getting these older links fixed!)

Last year I had got this link from Gerd. He also did a great job photographing this interesting morphological detail. But this old link has been gone out of date. Thanks for updating the link, Charles. The old forum is a great repository. It's be useful to have a link on the current forum.

There is a marvellous book about ciliates edited by Klaus Hausmann and Phylis C. Bradbury: Ciliates - Cells as Organisms. There you can find lots of morphological and physiological details illustrated with DIC, TEM and SEM pictures and, of course, description. There you can e. g. see that Actinobolina uses an arrangement of 6 pores.

So long, Wolfgang
