Interesting! I think this is one of the purple sulfur bacteria like Chromatium or Allochromatium . Red to purple carotenoids are characteristic, and while in most photos the sulfur granules don't appear so different in colour, I imagine they would still be yellow if the light catches them right. The...

This isn't Habrotrocha or any other bdelloid, though, this is a ploimid with a short foot and two toes. The head is shown well enough to see the ciliated field and mastax, which look like for instance Cephalodella . What little I've found on infected rotifers seems reasonably similar; compare the pi...

These are hypotrichs; you can see cirri along the margins in addition to the membranelles at the front. Most kinds ( Oxytricha and the like) are hard to identify for certain, depending on details of how the cirri are arranged. In this case, though, there is also the deep oral cavity with its peculia...

For the peritrich, that type of line pattern is typical of Pseudovorticella , in contrast to true Vorticella which only have horizontal lines. The two are very similar but it turns out became solitary independently. I understand it sometimes takes silver staining to distinguish them but not always; ...

This doesn't seem to have the groove typical of colpodids, either. You can partly see the mouth and oral cilia in the upper left of the photo. I think their shape mark this as a hymenostome, maybe something like Ophryoglena , which often have elliptical macronuclei but in some species more elongate ...

From what I can tell: #3 is not entirely clear, but from the colour I think it is plausibly a contracted Stentor such as S. multiformis , which are on a very short list of ciliates that produce bluish pigments. #8 is a fully intact Brachonella (unless some of the recent work on anaerobic ciliates ha...

These are spirilla rather than spirochaetes, which are like you say smaller, and also move differently. Spirochaetes are flexible and use axial filaments to squirm about. Spirilla are more or less rigid with external flagella; the shape takes advantage of the torque those produce to rotate through t...

These are flagellate spores being released from a sporangium. In contrast to free-swimming colonies like green Pandorina or pale Uroglenopsis , where the flagella project outward, you can see here they start confined along with the cells themselves. The actual enclosure is harder to make out but you...

February crystals
This month I had a chance to take my dissecting microscope out into the falling snow. It isn't easy to use in the cold with subjects that you can't get too near to, but a few results turned out well enough that I'd like to share them. http://www.photomacrography.net/forum/userpix/4234_Snow0268_1.jpg...
