Hello Forum,
usually you observe disc shaped testate amoebae like Arcella or Centropyxis sitting flat on your glass slide, like this Centropyxis discoides:
With some luck and glycerol I have been able to view the following two specimen from lateral. The next photos show some quite complex structural elements connecting dorsal and ventral shell, quite complex for a single-celler:
Diameters (from top) 240, 237 and 218 µm, Neofluar 40x, stacks of abt. 20 focal planes.
Cheers,
Hans

Re: Inside Centropyxis
Nice work and a new view in a well known subject.
Re: Inside Centropyxis
Those are great! It is quite true that we have been enjoying, in the main, just a single and therefore rather limited view of testate diatoms.
I had some unusual help when I managed a glimpse : viewtopic.php?f=6&t=7113&p

Hi Hans,
very interesting post! These amoeba look quite different from the side from what I would have expected. And the complexity of these single cell organisms always astonishes me. My view of a cell is more the orderly onion skin cell that a structure like this!

Re: Inside Centropyxis
Hello,
thanks for your comments. Views which SEMs cannot provide. Here's another example:
.
Pontigulasia (= throat bridge) build internal bridges to prevent Rotifera from highjacking the shell.
