Journey to the Microcosmos

Жыл бұрын

The Gastrotrich has long been a personal favorite microbe of several members of the Journey to the Microcosmos crew. But while we were able to see a lot with the microscopes we had at the time, James-our master of microscopes-has made some significant upgrades since then and this means that we are now able to see gastrotrichs in a whole new light.

Gastrotrichs are my favorite animals and I worked and still work on them (mostly marine) :) I am so glad to see another video about them :) However, I am almost sure the cover picture and the animal at 3:02 isn't a gastrotrich but a 'Dimorphilus', meaning it is a marine Annelida (and I worked on them as well) :) As for the expansion to freshwater gastrotrichs, it happened also in Macrodasyida although they are way less common like the genus 'Redudasys', which is also parthenogenetic as much as we know. They are less common in Europe but begin to be found in Brasil now. And for the question of freshwater chaetonotids, the molecular phylogeny is quite unstable so far (I manipulated these datasets :) ). What is sure is that chaetonotids were marine at first, but when in the phylogenetic tree they started to be freshwater is not the easy to infer :) It is almost pretty sure, as you say, that they returned, probably several time to marine environment :) There are also other marine parthenogenetic gastrotrichs like 'Urodasys' (Macrodasyida) or 'Draculiciteria' (Chaetonotida). So it is a mess, and the modalities of reproduction in gastrotrichs are quite diverse!

the animal at 3:14, which is also the thumbnail…i believe is not a gastrotrich! it looks very similar to an unusual neotenic polychaete worm called Dinophilus taeniatus (of which i was the first to report populations in the western hemisphere!) however it isn’t a complete match, i do still believe it to be very closely related, most definitely in the Haplodrili order!!! which is a very very fascinating order of unusual polychaete worms which i totally think you should do a video on!!!

Forgive my OCD... but the "Journey to the Microcosmos" logo in the beginning of every video... I can't help but notice that the 'O' in Journey is literally pixels away from being the top of a lowercase 'I' for the word 'Microcosmos'... If that makes sense. Condense 'Journey to the' by a tiny fraction - and maybe even color the O and I a diff color to make the lowercase 'i' stand out... eh just thoughts

Yes, the ciliation is, for most of them limited to the ventral side :) This is what helps them tho crawl or swim most of the time :) They are colloquially called "hairy backs" but it doesn't have anything to do with "Gastrotricha", and is quite confusing, it is because many Chaetonotida have dorsal spines made of cuticle, which gives an impression of hair :)

Almost. While it may have come from Greek, it is in Latin (New Latin, to be precise). The correct pronunciation should be [kʰae̯'tonɪda], I think. That's pretty close to what you said, except for two of the vowels being different, namely that the first vowel should rhyme with "eye" and the third with "lid". The third vowel could also be pronounced [i], rhyming with "knee", which is what you said, depending on what time period's pronunciations we're going for, resulting in [kʰae̯'tonida]. If we were to go with a more Greek pronunciation, then the first vowel would still be "eye" and the third would definitely rhyme with "knee", but also the first consonant would probably be different. It still gets the k-sound [kʰ] if we go with Attic Greek, but later forms of Greek like Koine and Modern would have it be [x], the same sound that ends the word "loch" in Scottish accents or the first sound in "Chanuka" when pronounced with the throaty sound rather than a straight-up h-sound. This makes it [xae̯'tonida]. To get the pronunciation you suggest, ['kʰito'nida], we would need to resort to Ecclesiastical Latin pronunciation, but even then, I think it would end up being [kʰɛ'tonida], with the [ɛ] being the same sound as in "bet", which is still a bit different. I hear Hank saying [t͡ʃɛ'tɑnɪdə], which I agree is not right.
@TazPessle
@TazPessle Жыл бұрын
@@ChefSalad yeh, I'm no linguist, but my main point was that the initial consonantal sound is not "ch" as in chicken. I know that χ is like loch, but noone is going to say it like that; just "k" is fine. Edit: the difference between uk and us english makes arguing over vowels kind of pointless. The consonants are where errors can be pointed to consistently.

@@TazPessle True enough. That and these languages are dead, so I suppose it doesn't really matter anyway. I just like being nitpicky sometimes.
