Desmids and amoeba tests

Post by Charles Krebs »

Sort of an odd mix of subjects. My recent samples haven't turned up any unusual interesting subjects, but one contained quite a few desmids and amoeba tests. So I gathered up a grouping of each (nowhere near as ambitious as Beatsy's diatom circle... that still amazes me!)

The desmids are oblique brightfield with crossed polarizers. Olympus BHS with a 4X and 20X objective.

The amoeba tests were taken "uncovered" (to avoid crushing any of them) with my Nikon MM-11 setup. I've been playing around with some simple lighting methods to give me brightfield, darkfield, Rheinberg (with a little added "top light" if needed).

These are wonderful. I've seen a lot of testate amoeba recently and mentioned them to my neighbour (a builder) who likes to come and have a look through the microscope now and again. I joked that people often say builders are slime, how would he like to see some slime that can build :) After looking, he suggested I arrange some like the diatoms, but I dismissed the idea. Too big, and not all that interesting - I thought. You certainly disproved that notion! Lovely images and very interesting too. It really is amazing that these complex structures are built by single-celled, brainless bits of protoplasm.

Might be an idea to embed some in resin and grind them down like a mineral section. Be interesting to see the inside and get clear cross sections of the walls. Hmmm...

Congratulations for winning the June picture of the month with that second image.
I'm in Canada! Isn't that weird?
