Thanks 75RR and also for the info !

Thanks Wes-- Actually I did put some of that sample into a culture dish with a kernel of corn :) . Not the exact drop that was on the slide though, I didn't think to do that but the next time I will !

Mastigamoeba

I have a fondness for the Mastigamoebas. The cilium is so mesmerizing. I wonder what the cilium is used for, it doesn't seem to be involved in locomotion.... perhaps some kind of sensor ? This one came from some algae collected at the edge of a local pond. It appears similar to the second Mastigamoe...

I like optics. And fine mechanics. I come from astrophoto so the razor-thin dof in microscopy kills me.

Re: Tried glycerin to slow down fast movers

I experimented some more with the MC solution, and did not have the same tragic results as the first two times. What I did find is that the protist were slowed down, but due to the increased vertical thickness under the slide cover, they were swimming in and out of focus so much I was unable to reco...

Thank you 75RR, Wes, and Asian. And thank you so much Bruce for the ID and discussion.

Ciliate feeding frenzy

I abandoned my first culture due to an explosion of too many creepy amoebas. I started a new one with a small piece of detritus from a local pond sample to which I added one kernel of boiled corn. After 5 days there was a swarm of small flagellates. I looked at the culture two days ago and noticed a...

Re: Tried glycerin to slow down fast movers

Here is an example where I questioned whether or not the PSH jelly was doing any slowing down. I don't know how fast this organism (P.Caudatum ?) normally travels but it was quite a "video game " sensation to have one hand on the fine focus and two fingers of the other hand on each of the x-y stage ...

I am sure that source is fine. Just thought that you might have mixed your own
I'm not sure if it matters, but I checked the ingredients on the bottle and they are:
water, MC, and salicylic acid. Not sure about the purpose (or effect) of the last ingredient.

Three Ciliates

I've become more and more fascinated by Ciliates, especially since I can grab them out of a larger sample using a stereo scope and transfer them to a flat slide. Here are three that I observed in the last few days in case anyone might find them interesting. I had some help from Bruce in identificati...

Re: Tried glycerin to slow down fast movers

For the MC I mixed 50/50, 1.5% MC and spring water. Under the stereo scope I could see the organisms swimming around in the tiny drop of sample water surrounded by the MC mixture. When I put a cover on and the suspensions mixed, there was no movement of the parameciums and high magnification confir...
