Testate Amoeba - Two Species - Video Added

Being notoriously bad at identification, I will only guess at the names of these shells and their contents. Ferry has a nice site with many images, but even then, I can almost never get it right.

These were all found in the sediment of dead plant material that has collected at the bottom of my microbe aquarium over the past year. And to think, I almost threw it out last week to start over. I'll have to rethink that now.

I also have video of three of these, but I wanted to confirm the ID with Ferry before I commit to a lot of time in mixing them down.

1. Difflugia acumenata? 10x.

2. Difflugia lanceolata. [Confirmed by Ferry] 20x.

3. Difflugia lanceolata. [Confirmed by Ferry] 20x.

4. Another Difflugia lanceolata. [Confirmed by Ferry] 40x.

5. A Difflugia acuminata. [Confirmed by Ferry] 40x.

I hope to see soon your videos with the correct identification by Ferry

Francisco, I have not started editing them yet, but they are looking good, and I had just cleaned my sensor today too.

Mitch,

Nice details with the 20x.

Thanks Charles, I already had that bookmarked, but seldom use it, as I find it hard to navigate. Sure has some very nice drawings though. Must be a thousand years of effort wrapped up in that site.

Rogelio, thanks for looking. I do use the 20x more than any other lens, if the subject will fit in the frame.

Mitch, I replied to your mail.

The book of Leidy (1879), which Charles mentions, is very beautiful. I am a lucky owner, but it is not very useful for identification.
Much better is the standard work of Penard (1902) which is also online at http://www.archive.org/stream/faunerhiz ... 4/mode/2up but in French

and the five British books from Cash, Wailes and Hopkinson (1905-1919) at http://www.archive.org/stream/britishfr ... 5/mode/2up etc. Old books, but still useful.

Charles, thanks for your excellent paper on Canon's Electronic Shutter Curtain on your site. I used a Nikon D700 on my Zeiss, but was never satisfied in handling it. I could only use it with flash, because of the mirror-vibrations. But after reading your paper last week I bought an EOS 550D. The results are indeed splendid, no flash requiered, vibration-free and a much much better LiveView-program. And its free! I am very happy with the camera. THANKS for the idea!

Ferry, Thanks for the ID and the reply. I will finish editing the video I got of these guys.

Good choice of a camera. I have the EOS 500D and will be buying the EOS 550D, in about a week. I am really looking forward to the manual control in video mode. The earlier model is all automatic. I can only control white balance.
