This is a new one for me. I found four individuals in a long kept sample. This is with the 40x objective.
Did not identify any definitive features, and as you will see, the shape is highly variable.
Any help is welcome.
Thanks

Likely an euglenoid.
Re: Green Fellow
Thanks zz and Jim,
After some looking around, I would say you guys have it pegged.
One curiosity though, I don't see a flagella anywhere, and I thought that was a diagnostic characteristic for euglenids?
Thanks for the help.

Re: Green Fellow
Definitely Euglena. Try phase contrast to make the flagellum apparent.
Quite a crop of diatoms!

Re: Green Fellow
Is this brightfield? If so, using oblique lighting may also make flagella visible, or if you were already using oblique, perhaps increasing the angle ("obliquity")?

I had an idea I might have some diatoms on this slide. I scraped some brown film off of the side of the sample container, sure enough the entire slide was covered with the same species at the same size. Fun.

Re: Green Fellow
Euglena may discard the flagellum when about to enter the cyst phase. Perhaps this video will clarify.

Re: Green Fellow
Thanks, Bill. It's an old one I did back in 2014, but it seemed to fit the topic. I think the Euglena shown in the original post might have lost its flagellum as in prepared to encyst.billbillt wrote:Thanks Bill P. for the interesting video ....

Re: Green Fellow
Adding a little obliquerol, will enhance your obliqueoscopy. Even a small amount will increase the amount of obliquement achieved ,until if enough is added, the level finally reaches total obliqueness, at which point you will be obliqnded.rnabholz wrote:Maybe Obliquiosity?
