As ever with biology, when you look more closely at things, they always turn out to be weirder and more complicated than you thought.

[@hausofjulian]

And the frustrating thing is that people who took 4th grade bio thinks they know enough about biology to simplify gender and sexuality into XX and XY. Not quite related to the video at hand, but just as equally aggravating.

Hello! I love the videos, just a suggestion. When showing an organism that moves too fast normally to see, maybe show both the slow captures and the normal speed recordings, just to give us some idea? Keep up the great work please!!

[@TheHighSpaceWizard]

They're using slow captures in the video. The top left corner shows you the speed magnification. With these organisms, showing normal speed would be useless.

[@benroberts3677]

@@TheHighSpaceWizard Yes I am aware why and how to indicate when they slow down footage, I'm just thinking that seeing these organisms move naturally, even if very hard to see, would allow a little bit of insight to how this world is so different than ours.

[@Crowbars2]

One thing I was thinking of... In a previous video, you mentioned that the water samples that are taken to look under the microscope are taken from around where James lives. But one thing I was wondering, is exactly how the microcosmos changes in different environments. It would be so cool to see the similarities and differences between the organisms in a sample of water from a desert oasis, and a frozen lake; or from a salt water sample, a brackish water sample, and a fresh water sample. Or even a sample from deep in a lake, and one from the lake's edge. I think such comparison videos would be pretty cool.

[@limiv5272]

Actually on several videos they mentioned we were seeing organisms from samples taken from all kinds of places that were then sent to James. There was the beach sand and the samples from the coral farm for example, so it's not just samples from one area that we're seeing on the channel

Like because you have added not only Spanish but Portuguese as well. Thanks a lot! I mean, I hear your videos in English but it's great you have added more audio languages. Also, videos are always amazing!

At 07:04, looking at the spirotrichia, the largest organelle and the two almost directly below it in the image seemed to be completely stationary, while the rest of the organism, its cilia and other inner bits are in motion. Why?

I wonder if the walking ciliate perceives the world in a 2D plane like we do.

[@sabatino1977]

You're missing a dimension there. We preceive in three dimensions.

[@Toluj330]

@@sabatino1977 I think the 2D plane this person is referring to is the "floor", but since they live in water I don't think that's the case

[@magellantv]

Wow! This was so fascinating!

[@JayDaPeace]

Question: I noticed that vacuoles appear and disappear rapidly in some of these organisms. What is this phenomenon and why does it occur?

[@vbgvbg1133]

Water diffuses into the cells due to osmosis, and the cell has to pump it out so it doesn’t burst and die. The vacuoles fill up with water and are expelled, something like a bladder. I think explained this in one of their other videos but I don’t remember which

[@dinogirrl1]

Thank you so much for your wealth of content! I know I can rely on your accurate descriptions to help identify what species I am looking at! I literally just typed ciliates that walk into Google and was brought here to confirm it's an Aspidisca! (Aren't they cute😍) Thank you for alleviating several hours of searching still pictures and not being sure.

[@NewMessage]

Silly Ciliate... Hypotrichs are for kids!

[@connordowning216]

I really like that you use morphology and microscopy to classify these ciliates but at a certain point you need to run PCR and sequencing to really know what your looking at. The price of these things used to be quite large but thermocyclers have come right down in price and presumably you already have a laminar flow and the BLAST database is freely available. Consider saving up for it

[@Solar-Eclipse_0j]

[@asilverfoxintasmania9940]

as some one who works with the microcosmos, yes.... and then add to that genetic info which then goes and changes everything yet again.

[@suelane3628]

Is there no DNA testing for such Ciliates?? Wouldn't this elucidate the relative relationships of these organisms. Though any answers might depend on how much lateral gene transference occurs in the Protist Kingdom.

[@Silverizael]

Often genome testing just makes things more confusing, especially when it comes to bacteria. Because the amount of horizontal gene transfer through the form of plasmids has resulted in a massive amount of genetic intermixing. This, in turn, makes it difficult to tease out what the actual ancestral relationships are between different bacterial species.
