Testate Amoebas: Blobby, Modest Shell Dwellers

[@rotifer]

*Anytime me and my fellow amoeboids are taking the night on the town, we'd always dress in our finest silicate granule clusters and cuticle outer coverings. We were the show stoppers! Then of course, there was always that one streaking amoeba who stole the show, peeling off their proteinaeceous shell and waving it over their cellular membrane and getting the rest of us in trouble! Ah, Good times...*

[@iloveeveryone8611]

I love reading your comments.

[@spiercephotography]

Hope you’re staying safe and sane in these weird times, Rotifer!

[@meltedyakkystick3891]

When did the rotifer become a flapper? lol

[@hunszaszist]

"waving it over their cellular membrane" That gave me chuckels.

[@chrismpbuchholz]

From 7:45 onward I had flashbacks to agar.io .. suddenly felt a lot of empathy for that little amoeba in a world full of monsters

[@TheRogueWolf]

So if I swallowed one of these amoebas and its shell went through my body unharmed, would you say I... passed the test?

[@JerryMetal]

:')

[@clray123]

If I dipped my balls in a pond with these amoebas, would you say the quantity of testes in the pond had increased?

[@YbisZX]

More likely - the test passed you...

What often floors me about these videos is that just when I’m understanding how small these single organisms are, there is something many times smaller swimming by showing me just how much smaller things can get.

[@alexwixom4599]

Can you do an episode on scale? How much room do they have between the slides of glass. If I were a rotifer how big would the slide be to me, would a moss piglet be dog sized or dragon sized? That would be interesting.

I think a really cool episode me and many people might find cool is a video on the organisms you wouldnt expect to find in the microcosmos. Ive heard that some fish and insect larvae are microscopic as well. Would be interesting to see how they interact.

[@TheTwick]

Are the testates found in the micro fossil record?

Can you make the scale marker stretch and squish with the zoom? Or add some markings on it that do? The numbers by themselves are really hard to visualize, and I want to get an intuitive sense of how big things are.

[@thea_kober]

To visualize the numbers on the scale marker better I usually compare them to millimeters, like, 1 mm is 1000 micrometers, so 200 micrometers is 0,2 mm, 500 is half a millimeter, etc. (Idk if this was useful, i suck at explaining things sorry :v)

6:52 you said some amoebas are distinguished using 'genetic techniques', but now I'm wondering how genetic testing can be done on such small creatures? How can you be sure the sample only has genetic material from the one thing you're looking at?

[@johndor7793]

What are the fluids moving around inside the amoeba at 0:50 ?

[@gurufoxx]

Wait...how does a testate amoeba make a little shell for itself without a brain or nervous system? How does it know HOW to do that? And why would it do that without a brain to have the thought about doing that in the first place? And following from that, how do you get reoccurring styles of tests when there is no brain or external communication to create the meme of a test shape or style? MIND BLOWN.

[@kf10147]

On the smallest scales consciousness isn't required for "decisions" they make a shell because of complex chemical reactions involving proteins that result in a shell. These reactions and proteins exist because of the dna that guides the building/maintenance of the cell. They have that dna bc that's what they are. Life on these scales is so fascinating bc it emerges from the rules of chemistry. If you want to hear more about these concepts I recommend kurzegesagt's videos on consciousness and emergence. They are very well produced and can help you explore these ideas more.

[@clray123]

@vexingcomos It's not just DNA. Watch video "What Bodies Think About" to see that the morphology of an organism can be modified without messing with its DNA. E.g. you can make a flatworm grow two heads by modifying some electrical fields in its cells. AND - that's the hammer news - the offspring of this worm will have two heads as well - the change is permanent. Or you can make an embryo of the worm develop into a different type of worm altogether.

Could difflugia use diamond for its shell?

[@maetos]

How a unicellar organism manages to assemble those rather complex shells out of say, two or three thousand particles it gathers from the environment, selects carefully by its shapes and puts all those particles painstakingly together, is a feat which remains quite the mystery to me.

[@ianmalkaviac]

Its amazing how similar they are to macro organisms like snails, coral, slugs, hermit crabs, and decorator crabs.

Danggit, i was really hoping you'd mention the Paulinella genus of testate amoebas, with it's 3 photosynthetic members (Paulinella Chromatophora, Paulinella Longichromatophora, and Paulinella Micropora. There are other non-photosynthetic members though). Outside of the singular event that resulted in chloroplasts, it's the only known case of primary endosymbiosis with a photosynthetic endosymbiont!

Nature spent well over 2,000,000,000 years refining the cell. What single cells are, what they do, is far more complex and intriguing than what animals or plants do as a community of such cells.
