[@Dismythed]

Primo, when you watch a nature show about tigers, do you expect a discussion of tiger bladders, see a cross-section of a tiger heart or brain, or the chemical composition of tiger mucus? Or do you expect to see a tiger in its habitat and hear a narrator waxing poetic about tiger movement? If someone says, "Journey to the Macrocosmos" or "Journey to Madagascar", do you get the sense that biology is what it's about? It's called "Journey to the Microcosmos", not "Journey Through Biology". They are just showing us the wonders in the microcosm.

This really brings me back to Gr. 11 biology when we covered the major phyla and each evolutionary advancement in each. It was amazing to see the complexity ramp up in each new phylum we covered, though each leap was enormous. Sponges to jellyfish to worms etc on to chordates. Our spiny phylum 🙃

Your new microscope tech is absolutely amazing! I'd love to see some of the earlier episodes remade with it.

[@rotifer]

*I remember when I was but a teenage larva in Planktonic High, my Gastrotrich buddy and I were part of the high school band. Later on we branched off and made a band of our own to impress the nematode babes at our school. We called ourselves the **_Mictic Sticks._** Quite the naughty name, I know, but let's just say that we were swimming in roundworm with each performance.*

[@Beryllahawk]

Wow the images here brought back some memories

[@rotifer]

*The term "Flatworm" is actually quite offensive among fellow platyhelminths. They much prefer being called "Worms that are cylindrically challenged", if you don't mind.*

[@sasilik]

What about rotifiers being pseudocoelomates? Don't you find pseudo being offensive like implying that rotifiers are not real somehow?

THOSE LITTLE GREEN DUDES AT 1:46 What are those?? I have them in all my pondwater samples and I haven't been able to identify them.

[@Wise_King_Solomon]

I know this isn't very specific, but they look like a type of euglenoid. Without more close-up or focused images it is hard for me to say for certain or with more granularity. I'm no expert on the subject, but I've looked at enough lake water and pond water under the microscope to at least call that an educated guess. Anyone who has a better idea or more experience with them, feel free to respond with it!

[@bone8352]

Could be Euglena viridis or possibly be grasilis. Unfortunately I'm no expert either just an observer.

A scientist once said that if all the matter on Earth was removed with the exception of the nematodes, we would be able to see the outlines of mountains, valleys, seas, rivers and other natural features formed by the masses of nematodes. Forests and cities would be dimly recognizable by the presence of specific kinds of nematodes, and we could even locate plants, animals and even ourselves based on the parasitic nematodes that infest each species.

[@stargrazing]

Good thing to keep in mind though is that flatworms are secondarily acoelomate, they’re traditionally thought of as the “basic” branch of the animals leading up to more complex stuff but they’re really nested pretty close there with “complex” other spiralians like mollusks and annelids. They had a coelom once but got rid of it cuz they’re too cool for it 😎

[@OlleLindestad]

This is a nice video, but it makes a crucial mistake around 4:45: annelids and humans do not share a coelomate ancestor. Coeloms evolved independently in the two ancient rivaling branches of bilaterian animals, the deuterostomes and protostomes. Humans are deuterostomes; annelids, nematodes and flatworms are all protostomes, so despite having or not having a coelom to different extents, they're more closely related to one another than they are to humans. Actually, for those deuterostomes and protostomes that do have coeloms, one of the most recognizable features of the two groups is that the coelom is created in different ways during embryonic development. In deuterostomes a part of the gut pinches off and becomes the coelom; in protostomes the coelom is inflated like a balloon from a solid mass of embryonic tissue.

[@arnorrian1]

Enterocoel theory states that coelom evolved from the gastric pouches of cnidarian ancestor of all bilaterians, but that some groups lost it later.

[@tsaszymborska7389]

You show us auch fantastic pictures every two weeks of organisms in which I see all kinds of parts acting together. Unfortunately I, and I guess lots of other people too, have no idea what all these parts do in the body of these organisms. Could you maybe make a (series of) video(s) in which you describe their functions?

[@thany3]

Is it possible to connect a highspeed camera to the microscope? It might be interesting to see those super fast moving "hairs" (I forget the correct term) in slow-motion of, for example, rotifers.

[@Dragrath1]

Regarding flatworms from what I have read there seem to be a number of different flatworms which were once all lumped together into one group but have now due to molecular biology and more detailed study been split into two groups. The Platyhelminthes discussed here a group secondarily reduced Nephrozoans(the historically accepted bilaterian group) which are have lost their coelum and the older but only more recently recognized Xenacoelomorphs which appear to be a true sister group to Nephrozoans having split off before the mesoderm or semi centrally organized nervous systems (as opposed to the more basal nerve nets) evolved. The latter provide strong evidence for a primitive microscopic and fairly planula-like (term for cnidarian larvae) "urbilaterian" a sister group to basal cnidarians which in a sense raises the question did worm-like animals diverge into cnidarian like forms or were early bilaterians cnidarian like animals which exhibited neoteny? On the other hand the prior group which this video focused on thus show that evolution doesn't have a direction with regards to complexity traits are gained and lost in equal measures with organisms that survive passing their genes on to the next generation. Regardless I think these are humbling lessons about nature and its myriad paths and it was a bit of a missed opportunity to not discuss this at least in passing.
