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.

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.

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

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?

Per his RU-vid 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.
