Re: Six Ciliates from this week

Nice sharp detail - the beating cilia. I'm intrigued by the squiggly feature on #1.

Re: Heliozoa IDs

Thanks for the reply Bruce. The more time I spend searching online the more I believe that 2-4 are Raphidiophrys. And what I described as ectoplasm is, I suppose, actually a transparent layer of scales. Next time I come across them I'll rack the focus back and forth more and perhaps try for a stacke...

Heliozoa IDs

Hi I will be posting some of my observations of Heliozoa to YouTube. I have some images I have tentatively identified and hope someone can confirm or correct them. I used the Protist Information Server http://protist.i.hosei.ac.jp/ in identifying them. The most confusing thing in identifying them is...

Lecane rotifer

While preparing a slide I applied a bit too much pressure to the cover slip. It injured a rotifer but provided an opportunity to observe a stationary subject. Standard and oblique illumination used. It was recorded a few months ago so I don't recall the objectives used - probably 20x and 40x. iSXDkB...

Re: Trithigmostoma, Chilodonella, other Chlamydodontina or something else?

Thanks for the reply Bruce. From what I've read this group can be hard to identify. I have recorded similar examples - cyrtos clearly seen, more features visible.

Trithigmostoma, Chilodonella, other Chlamydodontina or something else?

I find this cilliate grazing at the margins of algal clumps. Reasonably common, usually find 4 or 5 per preparation. Nearest example I can find on the net is Trithigmostoma. Shape seems right but I can't discern a cyrtos. Any suggestions as to its identity? 10x -20x - 60x objectives. unk_cil_10x.jpg...

Re: Amoeba

Hi 75RR

I took your earlier advice and purchased a 20x and 60x objective. I've shot some amoeba footage at 60x and will be posting it to my YouTube channel.

Re: Amoeba

Hi janvangastel Perhaps you could culture your own. I collected some pond water (with algae in it) and placed it in a large jar. I added some drops of liquid fertilizer. A few days later it turned a nice shade of green. It's full of small round algae (see picture). It seems to be the perfect amoebae...

Dero sp.

Found this specimen in a sample of pond water I have brewing at home. A worm with a "hand". After some research it appears to be a species of Dero from the family Naididae, the hand being the worms gills. Camera at prime focus using 4x and 10x objectives.

Vorticella?

Can anyone identify these cilliates? I find them attached to algal clumps sweeping up food. As their lower half is always obscured I can't tell if they have a stalk or not. I've never seen them contract (or move). First image 10x objective, second 40x. unk_cilliate.jpg https://farm8.staticflickr.com...

Growing on the cover slip?

Can anyone identify this? I think it is growing on the cover slip (the rotifer was moving under it). I recycle my slides and coverslips. I clean them in disinfectant and dry them. Perhaps I missed something.
