Diatom and Amoebidae?
Diatom and Amoebidae?
The diatom (as yet unidentified), is about 65µm width, Marine sample, Alboran Sea
There appear to be kinetocysts traveling along axopodia within the diatom

Re: Diatom and Amoebidae?
Superb details 75' - so much more to ponder than the empty shell.
I'm off to have a look into the details - you've gone and got me all interested you blighter!
The similarity to intracellular transport (the ubiquitous microtubule?) of plant cells is obvious too!
I don't suppose you could add to this 75' - it really is truly fascinating.

Thanks mrsonchus
have a stack that shows the shape of the frustule with more detail than was apparent in the video.
Curiously, it has chamfered corners (one would have thought that would help with the ID but no luck yet)

I think that the diatom might be: Striatella unipunctata
Please see Fig 1 of

IMO the image and video you posted are at least as fine as those in the article,
Yet, is it really composed of two creatures ? perhaps, if it could be inverted, upside-down, so the "dorsal" or "ventral" side was visible...

Great catch!I think that the diatom might be: Striatella unipunctata

+ fantastic link on "Interactions between Diatoms and Bacteria" Plenty to digest there

That's a lovely image ... and the video action is amazing.75RR wrote:... have a stack that shows the shape of the frustule with more detail than was apparent in the video.

Too many 'projects'
Re: Diatom and Amoebidae?
This is amazing! To see directional movement of particles inside the cell like you show is incredible. Also the stack is beautiful. Thanks for sharing 75RR.
