Phylum Rotifera Part 1: General Characteristics

It's time to wrap up our study of Gnathifera, and this means investigating phylum Rotifera. These are the wheel animals, and we will need a few tutorials to get through them all. Some species are free-living and some are parasitic, and you've probably had some in your body, since they're pretty much everywhere. Let's go over some general characteristics of this phylum now.

Journey to the Microcosmos explained the rotifers so well, but this video adds that extra content with Dave flavour.

[@plotinuswashere]

yes, journey to the microcosmos is highly recommended

[@JamsGerms]

aww thanks!

[@Corvus67]

Massive respect to you, for covering the different major and minor phyla... It helps so much in cutting down study time in my Systematic Zoology subject in college.

[@Ehsan-the]

Cool, can't wait to see the next part

[@TheseNuts2]

Things everywhere and all around us, fascinating!

Acanthocephala and aves, have one thing in common. We now know they belong to bigger groups, but in textbooks and on websites, we still treat them as a separate rank. Acanthocephala belongs to phylum Rotifera, eventhough we sometimes still call it a phylum. Aves belongs to class Reptilia, eventhough we most of time call it a class. Having the same rank within another rank makes taxonomy more confusing, so I wish someone re-rank groups so people wouldn't keep on ranking groups in their traditional ranks that we have continued to do so for 270 years. The main reason why we know certain groups belong to bigger ones is because of DNA... and maybe some physical and fossil evidence.

Paraphylogenies abound, wait until we get to the Arthropods

[@billyr2904]

@@ryanhelcoski6894 Hexapods are cladisticaly crustaceans, but are taxonomically seperate, even though they should really be crustaceans. Crustaceans are also not bound to water, crustaceans moving to land evolved many seperate times in the group, including hexapods.

[@user-ut9ov8xm4m]

@@billyr2904my professor called them "subphylums". Makes it much easier to explain. So subphylum crustacea & subphylum hexapoda are both under phylum Arthropoda.

This guy is taking a short vacation from dunking on the flat earthers.

[@FlatEarthKiller]

I’m dunking on Dubay

[@Bretaxy]

It gets frustrating when the flat earthers run out of arguments.

[@TheseNuts2]

I can't find a source for the rain drop nucleus formed by them :( Can you help?

[@whatsup3519]

Could you please make a video about English phonics spelling rules

[@blackboots2989]

What an amazingly complex little creature! 🔹🔹🔹

[@murph8411]

Finding them in large amounts of water can be problematic though. I can’t recall ever finding one when I’ve been trying to find organisms to view under a microscope.

[@Top-Code]

Where are you looking for them?

[@leadeater2]

holy shit new phylum

[@nickysantoro9194]

Hey P Dave can you please do an episode on browns gas? Specifically george Wiseman hes selling a kit that seems could be prototyped for much cheaper than the 2500 dollar price tag. Also there are reports of a browns gas inhaler being used in germany for health reasons? Is there any truth to any of the myths around browns gas?

[@astroevada]

Yo dave! You got stuff that could help GSCE year 11 students? Love your stuff!

[@orangejoos6288]

I LOVE ROTIFERS!!!

[@alexalford7874]

I came across these little guys a few times under my microscope. I've been trying to find tartigrades, but in the process I've found rotifers

[@thetrevor861]

Hi Dave. I have recently discovered that you are not actually a professor. But I am already aware that you know a load of stuff. More than me, so please crack on ! And thank you.

[@alisaurus4224]

Per his KZbin bio, while he’s not currently employed as a professor, he has taught various subjects at highschools & colleges, so i think it’s fine to call himself Professor Dave.

[@chadstrong7714]

Are you still planning to do a video on Dr. Eric berg or have you moved on?

[@ProfessorDaveExplains]

I will at some point, a lot on my plate at the moment.

[@orangejoos6288]

Keep it up

Neat! [takes picture]

[@WallyWaldo87]

I just want more flat earth debates

[@waelfadlallah8939]

Does these creatures considered alive

[@marsar1775]

yes, they are animals. just really small ones

[@Corvus67]

They are alive, they aren't talked about much since they are part of some of the minor phyla...

[@MrTylerStricker]

Rotifers invented a superior, biological version of the wheel millions of years before humans did & use it in substantially better ways.

[@GeraldChinwendu]

I need a friend, that will help me in biology

[@notdominic7109]

wow

[@billyr2904]

I thought you would have more than one video for the major phyla. Rotifera is a minor phylum (why do sponges get one video?)

[@ryanhelcoski6894]

tbh, because that's the first animal phyla video I wrote before realizing it would be best to split things up. I then over-corrected by writing like 7 videos for Cnidaria lol
