I'm trying to identify elements of a Vorticella anatomy, but I am puzzled by the 2 round, dark features in this video snapshot.
They float around the entire cytoplasm and I counted up to 4 of them, as shown in the second screenshot.
For lack of a better term, they appear to have the texture of a raisin. Quite different than the other food vacuoles.
Would anyone know how to identify these round dark features?
Thanks!

Re: Vorticella Anatomy
It looks like ingested matter (food). The more transparent food vacuoles just happen to contain smaller particles.
Since this is "Identification help," can you be sure it is not Pseudovorticella? From these images, I can't tell.

Being brand-new to the hobby, I appreciate the question, which was an opportunity to look a little deeper.Bruce Taylor wrote: ↑Fri Apr 02, 2021 12:42 pmIt looks like ingested matter (food). The more transparent food vacuoles just happen to contain smaller particles.

From what I learned, this snippet from the video should help.
"Several peritrich genera contain more than 50 nominal species, for instance, Vorticella and Epistylis. A first split of the former into Vorticella (silverlines in trans-verse rings) and Pseudovorticella (silverline pattern reticulate) was performed by Foissner and Schiffmann (1974), and has been widely accepted (Warren 1987, Song et al. 2009)"

So it looks like we are looking at a Vorticella?

Re: Vorticella Anatomy
Yes, nicely done! The reticulate silverlines in Pseudovorticella can be extremely faint, but I do think you've resolved the pellicle well enough for a casual identification to Vorticella.

Re: Vorticella Anatomy
Thanks. Now I'll need to find a bonafide pseudovorticella!
