Actinosphaerium

Post by NikonUser »

It's been almost 2 years since any of these has been posted.
A huge protozoan that is just about invisible under normal reflected light. I saw it only because it cast a shadow on the the white background and then it took a while to see what was causing the shadow.

” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”

Excellent work. It looks like a Christmas Tree ornament.

NU,

interesting species. Here winter has come and now every pond is ice :( But a couple of weeks ago, when it was already pretty cold, I found Actinosphaerium eichhorni, too.

If you like a challenge, try to find the nuclei - there are lots of them.

Regards
Ecki
