I found this recently posted little article on the NPR website that looks at the interesting "dance" of a courting jumping spider. It includes embedded videos.

The similarities are certainly there, but they might better be thought of as cousins, Mitch. They represent different families of Pertrichia (Subclass), Sessilida (Order). Pyxicola is a genus of the Vaginicolidae family and Vorticella is a genus of the Vorticellidae family. At least that is how the ...

Hi Mitch, thanks for sharing this update on what's happening in your aquarium. I'm intrigued by how the populations of differrent critters come and go over time. Clearly, these guys are in a boom phase. Although I'm no expert, I'll put in my 2 cents worth towards an ID. I'm thinking some sort of Col...

Just comparing the pictures, it looks a little like this Ske. http://earth2geologists.net/Microscopes/photogallery/Nikon_Ske_Pol.jpg This link is taken from James McHone's website, where he has quite a bit of information on polarized microscopy. http://earth2geologists.net/Microscopes/index.htm Anot...

If we are right about this being a stentor, it would appear to be in its free-swimming mode. I would assume that the oral area would be towards the upper right. DIC gives a very strong cross-sectional view, and since what appear to be the nuclei are so visible, this is probaby a mid-depth view. The ...

Looking at this photo, I'm reminded of Arturo's Stentor photo with its "string of pearls" nucleus.

"An Illustrated Guide to the Protozoa" (2nd ed) suggests that the amoeboid motion in Pelomyxa is distinctive "with the cytoplasm flowing along the center of the body and spreading out, fountain-like, at the anterior end." I wasn't quite sure what to make of the next sentence, regarding feeding. "The...

Brian, looks like a line break got introduced into the url for the third photo. Maybe you can mend it back together (with delete or back space) and then see if the image displays on this page. [Fixed by Admin] I think that your "failed" darkfield actually turned out just about right for capturing th...

The vast number of ciliates with their many similarities makes identification difficult, and I'm hardly an expert. I did run across another possibility, which looks similar to Prorodon, Holophrya. I'm assuming that the wedge shaped area towards the bottom of the picture (around 7 o'clock) is part of...

You are correct that your Windows XP will likely not use more than about 3GB of RAM, but this is because it probably is the 32-bit version of the operating system. It really is only since the introduction of Vista and more so Windows 7 that PC manufacturers have switched over to the 64-bit versions ...
