Here is what I want to see when I click that link: a picture. Of a bacterium. Next to a ruler. Thank you.
UPDATE: My bad, there are plenty of pictures in the supplemental materials downloadable further down the page
ReplyBlech.
This is one of those cases where the genetic material is repeated multiple times inside the same "organism". It would be considered to be a filament made up of multiple cells, except that there isn't anything separating the individual cells, so it's technically "one cell".
It's like roping together 200 boats and claiming that you've created a mile long boat. You sort of did, but it's not really the first thing people think of when they see that phrase.
ReplyInteresting. It seems like https://en.wikipedia.org/wiki/Thiomargarita_namibiensis only much larger.

ReplyIn San Pedro CA there's a beach called White Point Park, named for the mats of white sulfur oxidizing bacteria that grow in geothermal spring water. A Japanese family ran a bath house with the water from a geothermal spring but an earthquake damaged the flow and then being sent to internment camps ended it. I was gazing in the tide pools there when I got a whiff of sulfur, like at a hot spring, and followed my nose to a tide pool full of white fuzzy sulfur oxidizing bacteria (I think).

ReplyI guess it's not thick enough to see with the naked eye.
ReplyI for one welcome our enormous bacteria overlords.
ReplyHuman neurons can be a meter long.
ReplyReally neat bacterium. Sounds like it's on the verge of becoming an eukaryote.

ReplyHum... I'm unsure and my sea spider sense is tingling. My first impression would be an egg sack like those from Opisthobranchia that could explain the DNA in pouches, or maybe a small bryozoa. If is covered in bacteria it could explain the genetic analysis.
Another possibility would be some kind of crystals growing from sulfur and covered in bacteria.
We need and electronic microscope image here and hystological cuts stained with gram.
ReplyAmazing that cell walls are strong enough to maintain integrity at that size!
Replywent down the rabbit hole and found this: Largest single cell organism (1.6 inches) https://en.wikipedia.org/wiki/Valonia_ventricosa
ReplyNot the only unicellular organism visible to the naked eye. For example: https://en.wikipedia.org/wiki/Valonia_ventricosa
ReplyI guess being long and thin they don't violate the square/cube laws that normally keep bacteria from getting too big given that they have to use their outer walls rather than mitochondria to respirate. Still very impressive.
ReplyI need to find a good youtube video on the physics of cell membranes and cytoskeletons. It's completely wild that a lipid bilayer can be strong enough for an ostrich egg or flexible enough for an amoeba.
ReplyVery bad news
