Those giant white hair looking things. Each one is a **single cell** bacteria. It is the largest bacteria known to man with each cell growing up to 2mm. You can see them with the naked eye and they are even strong enough to be picked up.

They are also unique as they are the only bacteria where the dna has a nucleus like membrane around it.

I thought that was the difference between prokaryotes and eukaryotes, and there were single-celled organisms with a nucleus... Did I misunderstand something?

No that is almost always the case. Life is filled with exceptions though, and this is one of them.

Mammals are supposed to give live births, but a platypus lays eggs.

"My skepticism about the authors' claim that the genome of 𝘛. 𝘮𝘢𝘨𝘯𝘪𝘧𝘪𝘤𝘢 is localized in mem­brane-bound compartments ─ which they call "pepins" ─ stems from the fact that their techni­cally excellent EM images do not show a continuous membrane, at least not in one focal plane (Figure 4, F+G)."

Characterization of the pepin organelles by FISH and correlative TEM as well as membrane and DNA staining. A─D: Pepins (arrows) in the cytoplasm of "Ca. T. magnifica" (class Gammapro­teo­­bacteria) are labeled with the gene­ral bacterial probe EUB labeled with Alexa Fluor 488 (A, green), Gamma­pro­teo­bac­teria specific 5 probe Gam42a labeled with Cy3 (B, yellow), Thiomar­garita-spe­cific probe Thm482 labeled with Cy5 (C, red) and with DAPI (D, blue). E TEM of a serial thin section con­secutive to the semi-thin section used for FISH. The FISH and DAPI positive pe­pins appear as elec­tron dense organ­elles under TEM. F,G Pepins (from E) under higher magni­fi­cation; pepins are delimited by a mem­brane (arrowheads) and contain numer­ous ribosomes which appear as small electron dense gran­ules.

Not my area of expertise, but you seem to know what your talking about. I'll give a read to the link if I remember tomorrow but I boosted because this is all very interesting.

I'm a fan of Jean-Marie Volland's and his colleagues work! however, this includes criticism of one of their claims. because this is science 😀
