Darbyshirella species?

The link to this video was sent to me by Veselin Andreev. It is a stunning compilation of fragments of a highly interesting reticulate amoeba, probably a Darbyshirella species. The video is incredibly detailed, showcasing not only the beautiful cytoplasmic streaming but also all inclusions, such as nuclei in various stages.

His commentary on the video:

“The video begins by showing cysts with visible internal activity, followed by footage of a freshly hatched cyst. Next, you’ll see detailed views of the network and the intense cytoplasmic activity. Towards the end, I was able to capture mitotic division of the nuclei. What I find particularly intriguing is that in regions where the nuclei undergo mitosis, the surrounding cytoskeletal activity and cytoplasmic streaming are notably reduced compared to areas with interphase nuclei.”
