Litonotus... fission separation anxiety? ;-)
Here is the final stage of reproduction by fission of what I think is Litonitus (although I don't see the two prominent macro-nuclei, so please correct me if I'm wrong). The top photo shows the division process nearing completion. In the middle there is only a single "elastic" strand remaining between the two... the lead individual seemed eager to break this bond. In the lower frame you can see both individuals after separation.

Great set of sequencing shots there Charlie. Details and colors all top notch as usual. Thanks.
Sex is sex even in the primative world of microorganisms I suppose. After the deed is done, both parties are ready to split! No pun intended but the more I think on it yeah it is intended.the lead individual seemed eager to break this bond.

Good observation Wim about the cloning. Don't let it out though, someone may try to pass legislation on it.
However your comment concerning cloning, did bring to mind the subject of "stem cells" and how they are used to replicate new tissues in the human body. Makes one wonder about not only the reproduction methods of protozoa but cellular reproduction, structure and function as a whole. Thought provoking isn't it?

Been there, done that Wim! It's called "divorce!" Sorry Wim, I couldn't help myself but it was the first thing that popped into my teeny little mind.Imagine that you meet someone, that you exchange genetic material and that you both become someone else!

Mike... this is pretty much the color I get with phase. Actually it all depends on the "white balance" on the digital camera. If I'm doing mostly phase-contrast I'll do a "custom white balance" and then it comes out more of a neutral grey. If I use the white balance that I had set for brightfield it comes out a little blue. BTW, I get noticeably different color with different objectives and they are all the same series Nikon.

Wim, Mike... I find the "background color" of phase is very sensitive to filtration or color balance. When I made color prints in the darkroom (with an enlarger!.... remember those things ) that same color... grey with a "hint" of blue... was also very sensitive to filtration from the color head. To my way of thinking there really is very little, if any, "accurate" color in phase contrast anyway, so to filter (or color balance) it to a tone that is pleasing only makes sense. In digital form it can look quite different depending on the color space in which it is viewed. I normally work in Adobe RGB, but must change the color balance a fair amount to have it look the similar when posted to the web.
In the same sample where I found this Litonotus I also found the final "tug-of-war" of this reproduction. Not sure what it is... possibly Stichotricha. I figured Ken would like it since it seems like the leader is trying to use an amoeba to complete the "break".

The Amoeba is probably the lawyer who makes the most profit from this divorce
Interesting info on the colours. The colours look different in different browsers, and also on different computers. I work with a Macintosh and I sometimes notice my images look a bit dark on other people's computers.
By the way. We are quite lucky that our subjects are so extraordinary. When you photograph portraits of humans it is much more frustrating when the colours (I mean colors:D ) change becasue everyone is so familiar with the subject.

Everytime some ciliates find themselves in a jam, who do they turn to? The lowely amoeba. Great image as usual Charlie, enjoy them. Thanks
