A match and a shell

Yes, you are right. It was a failure (DIC wise). I should have tried fluorescence which may have given interesting results.

Egg of Artemia Salina

I revisited some old stacks which I have failed to nail. In this stack I found that the some of the single images were good by themselves, so I selected this one which had halo rings in the background. It is an egg from Artemia Salina in DIC. https://farm5.staticflickr.com/4467/37864561861_2e37a168e...

Water Mite

I found a tiny (what I believe to be) Water Mite in a sample. It was redish/brown. The size was just bigger than a large copepod, so I managed to get most of it with 4X objective. It is a water mount with a thick layer of water and a coverglass resting on small blobs of bees wax. I tried all possibl...

Re: Please help ID (some kind of rotifer I guess?)

Johann, great shot! Funny we found the same species just a week apart. First time I stumbled upon one. Seems rare, at least in my samples. Your image also shows the "fried egg" looking structure inside. Any idea what that is?

Video of various things

When I go through my samples I usually film interesting subjects that I later take stacks of. Some are too fast and impossible to capture in a photograph. In those cases I find video to be good for documentation. Here is a selection of the last month of video clips put together. https://youtu.be/uVb...

Re: Two Rotifers - Euchlanis & Polyarthra

These are indeed lovely images. I'll second Polyarthra ; the first is a Lepadella with the head extended. You can see the notch for the foot and the two red eyespots very well, both of which are characteristic. In Euchlanis the foot emerges from a wider space between the lorica plates and there is ...

Hydra - Various magnifications and techniques

I was going through some sample jars I collected four weeks ago in a nearby pond. Attached to the surface inside of the glass jar, I discovered two Hydras close to each other. I sucked one of them up and tried to take some photos, but she refused to sit still despite my efforts to talk nice to her. ...
