Isn't that something like a hedgehog or a porcupine spine section?

Best wishes, René

Does remind me of something, Charlie. Now what was it, it always ends up under my shoes

Gorgeous Walter! You want to exchange some slides? I've got a nice brackish bloom on my hands right now!

best wishes, René

Nice images Charlie. What a strange eyes those waterfleas have!

Best wishes, René

Got a nice fresh sample in from a brackish harbour with a massive bloom of Coscinodiscus jonesianus var. commutatus, http://bibdigital.rjb.csic.es/ing/Libro.php?Libro=1006&Pagina=452 10x/0.4 http://www.photomacrography.net/forum/userpix/154_Antwerpen_Haven_A_852017_10um17p_10x_S_rw_MB_R3S2ed_1.jpg 2...

Hi guys, it's the time of the year again. My son found this lovely little thingy: http://www.photomacrography.net/forum/userpix/154_Spoorsloot_Haren_2742017_10um33p_20xS_rw_170427_155821ed2_1.jpg http://www.photomacrography.net/forum/userpix/154_Spoorsloot_Haren_2742017_10um33p_20xS_rw_170427_155736...

Gorgeous images Hakan.
The skeleton is in fact partly hollow. In the first images, it looks like the stacking was focussed on that hollow structure instead of on the outside.

Can you do an anaglyph of them?? The 3D picture would be stunning!

Best wishes, René

yes they are! BTW, the first one is not a heliozoan, but a suctorie. That's a strange member of the ciliates.

Best wishes, René

wow, in the best of the Moeller tradition. Beautiful!
With respect,
René

I'm pretty sure of that as well. But which one...

As Pau says, a chromosome is not purely dna but highly complexed with proteins. The 'holes' are just regions with more or less protein. Check the difference in staining in the neighbouring nuclei.

HTH, René

Interesting. Really that small??

Any kelp around?

Best wishes, René

Nice detail Rik, got a bit dizzy from all the traffic whizzing by ;-)
Hope Bruce can help you with ID,

best, René

That's a typical desmid, a green algae , Kit!

Best wishes, René

Great images of some ugly ducklings, Walter!
