Re: wind scorpion, solfugid

I did not know they responded to UV light. I will definitely try that when I next find one! Thanks for the comment.

Re: dinoflagellate?

Thanks Bruce. I didn't think it was damaged at the time, but now that you mention it, I guess that probably fits it best.

dinoflagellate?

Rigid body, rotates slowly forward, and every once in a while it skips forward by one body length, and then continues rotating slowly forward. I thought it should be a Ceratium, but it just doesn't look like the images on google images or in any of the books I have. It also has a row of sparse cilia...

I think this is salpingoeca. 100x DIC, 6 frame stack pmax. The stack caught the flagellum in various positions. Lower body sphere ~ 5m diameter. https://lavinia.as.arizona.edu/~swest/micro/salpingoeca_xga.jpg sometime later, I caught these monosiga. I think there are two diplosiga (pointing down). G...

worm identification

I can't seem ID this [flat]worm. It's a little under 3mm long. The head has 4 prominent plates which extend and contract. Their edges are lined with cilia as is the side of the head. No cilia anywhere else though. Found it at a local man-made pond. Upper body and head (4x DF) https://lavinia.as.ariz...

Thanks for looking Ken and Walter.

Walter: Yes, the beam splitter is under the condenser. I used a pellicle for a full frame Sony A-mount camera. The flash is off to the side. Not optimal, but it was simple and works reasonably well.

Hi Ramon,

I don't have a much higher res image. I sent reduced sizes to zerene, and then (as usual), I delete all my original images that I stacked.

Here's the largest I have:

Very neat. These things are everywhere! No such wonderful goodies on tree bark here in S AZ -- the sun would have fried them in an hour.
