Rhodelphis mylnikovi was isolated from fresh water like Rhodelphis limneticus, specifically from the Étang du Manet pond near Montigny-le-Bretonneux in Ile de France, France. Analyses place it close to R. limneticus, and it shares 95.16 percent of the nucleotides in the 18S rRNA gene with that species.
The full illustration shows simplified anatomy of Rhodelphis mylnikovi in the upper left corner. The lower part of the image shows behaviors observed in the species: binary fission; cannibalism, shown by a darker gray individual being eaten; and predation, shown by an individual that consumes a specimen of Bodo saltans with its parts labeled for clarity. Why? Uhm... why not?
In the cases of cannibalism and predation, pseudopodia are shown, which are cytoplasmic protrusions that reach out to capture and swallow prey. This detail matters because the simplified anatomy diagram also shows a pseudopodium, and it's important to note that this structure doesn't appear all the time.
These illustrations of Rhodelphis mylnikovi are based on the microscope photographs in the article by Prokina K. I. et al. 2024: "Morphological and molecular characterization of a new member of the phylum Rhodelphidia". The organism itself has no color. All colors in the illustrations serve an artistic and educational purpose and do not reflect the organism's true appearance.
To create Bodo saltans and its structures, I relied on these works:
- Harmer J. et al. 2018. "Farming, slaving and enslavement: histories of endosymbioses during kinetoplastid evolution".
- Midha et al. 2021. "Bodo saltans (Kinetoplastida) is dependent on a novel Paracaedibacter-like endosymbiont that possesses multiple putative toxin-antitoxin systems".
- Malysheva et al. 2007. "Mitosis of the free-living flagellate Bodo saltans strain PS+ (Kinetoplastidea, Bodonida)".
