Bursaria Truncatella
Bursaria Truncatella
Last night I observed for a while a sample in a jar, using an astronomy eyepiece as a magnifying glass. Aside from worms, and rotifers, I noticed some very big ciliates with a disctintive shape. Some of these ciliates were just beneath the surface, so I took a little dropper, placed it on that spot (while looking through the eyepiece), and took a sample of water. I placed all the water on the slide, an voilà, two big Bursaria Truncatella were swimming over the slide.
On the first section of the footage, I recorded the ciliate swimming without coverslip, since I find very interesting to observe how the ciliate moves in all directions when the coverslip isn't limiting its motion. I'm happy about how the 100 x dark-field turned out; it's isn't always easy to evaluate the right exposure and often I get under or over exposed videos.
I include some photos of the puddle (I like to call it the "magic puddle") where I get all my samples. It's a puddle that forms occasionally on an Island, after the river floods a lawn. After I few hours, the water dries out but the puddle remains for two or three days, depending on the season. The variety of micro life that I find there is incredible, including some not that common specimes.
My equipment is the usual (Amscope 120b and iPhone 5s), and the magnification used was 40 and 100 x for DF, and 200 and 400 x for BF.

Very nice video, Javier! Nothing like a magic puddle Very exciting to see such a large ciliate.

Nice find and great imaging! I am very impressed with the quality of cell phone cameras these days, and what can be done with them afocally.

Excellent! I love those, especially in darkfield. Amazing detail on the 100x footage!

Thanks tlansing, Dubious, and Sciencia Matters for your comments.
Imaging with phones using regular adapters take a low of work IME, but the outcome can be certainly rewarding.

Lovely, and good to see the source location too! I'll have to do some hunting this Spring/Summer
