Hello- Nice shots! Have you tried googling the anatomical structure/morphology of Diatoms? There are quite few designs!

Here is a start: https://diatoms.org/glossary/raphe

Hi einman,

I have searched through that excellent diatom site but came away still none the wiser. I have now been in touch with Sarah Spaulding to see if she can shed any light on the subject.


I think nobbles should read nodules.

Thank you Kurt, now as I look at them I do see that there is no protrusion but a hole.
