Hypotrich (possible Urostyloid) releases a Diatom
Hypotrich (possible Urostyloid) releases a Diatom
I'm very happy to finally find a Blepharisma (I'm almost sure it is a Blehparisma) and to catch the moment when it releases a Diatom. I'm also happy with the quality of the video, given my current equipment, although I made the mistake to use a blue filter for dark field that ended up adding a weird hue. It's too bad that the old phone I'm using does not allow me to avoid auto-brightness, it's a nightmare when shooting dark field. But all in all, I think this is a nice outcome.
Video details:
200 x Bright field
100 x dark field
100 x oblique light
Amscope 120 b and iPhone 5s.

Very nice video
Re: Blepharisma releases a Diatom
Beautiful video, thanks Javier. I'm pretty sure the splendid beast you share with us is not a specimen of Blepharisma.. I will try and look up what this protist is...but it's not Blepharisma. Great image cature, thanks again. charlie guevara
Re: Blepharisma releases a Diatom
Thanks, Carlos and Charlie.
It's good to know it's not a Blepharisma. I did notice some differences in the structure of this ciliate compared with the real Blepharisma, but I thought it might have been another species from the famous pink ciliate. Please, Charlie, let me know if you find out what it is.
Stay safe,
Javier.

Re: Blepharisma releases a Diatom
Very nice video! As Charlie pointed out, it's not a Blepharisma. This is a pigmented hypotrich, and probably a urostyloid. Species with pink cortical pigments occur in a number of hypotrich genera, including Pseudokeronopsis, Diaxonella, Anteholosticha, Urostyla, and Rubrioxytricha. Identification of your ciliate to genus would require a clear view of its somatic cirri, measurements, and information about its habitat.

Re: Blepharisma releases a Diatom
Was the diatom just mot digestibe?
Re: Blepharisma releases a Diatom
Thanks, Bruce. That is very useful information.
Don, I recall something about not being an easy dinner for protists because of their silica wall... but I might be of course wrong.

Re: Blepharisma releases a Diatom
For many ciliates, diatoms are a dietary staple. If they're hard to digest, certain ciliate groups (e.g. cyrtophorians, Frontonia, hypotrichs like this one) don't seem to mind. For some protists, such as Jenningsia diatomophaga, diatoms are the preferred food.
Re: Blepharisma releases a Diatom
I captured a few days ago this Frontonia engulfing a small Diatom. Seems like it can't have enough of them.Bruce Taylor wrote: ↑Fri Aug 06, 2021 2:05 amFor many ciliates, diatoms are a dietary staple.
