...of those objective lasers to try and cut holes in tiny cells and see whether they can heal. The way stentor pulls itself back together is like:

I don't know about all large or small cells, but for Stentor, I always show a video in class of one getting half-eaten by an amoeba. The half that gets pinched off just swims happily away. So I might guess that Stentor in particular is adapted for wound healing and regeneration. I need to get one...

I have another one where I accidentally co-cultured some big ciliate and I ended up selecting for some multicellular algae. I think the ciliate either pressured them to create floating blobs or just ate up all the unielcellular algae so the other stuff took over.

Amazing! I'm not the only one who finds radiolarians in shallow water. Super cool.

It's pretty cool! Are you sampling in coastal/shallow water?

I guess it's an acantharian, but it is not one that I've come across before!
