Phylum Brachiopoda: The Lamp Shells

Continuing through Lophophorata, we arrive at Brachiopoda, the lamp shells. There aren't many of these left today, but they are fascinating tiny little sea creatures, so let's learn about them now!

Hi Professor Dave, I wanted you to know I never attended a single chemistry lecture this semester, opting to watch your videos instead. I just took my final yesterday and ended with an A in the class. Thank you so much!!

It's been a year and a half, and you are finally finishing Spiralia!
The ecdysozoans contain the 2 most widely distributed and successful phyla on the planet. I'm of course talking about the nematodes and the arthropods, both phyla are found in every habitat on the planet, and have very high populations (in terms of number of individuals). In fact, there are so many nematodes, that 4/5 individual animals are nematodes.
The phylum Arthropoda should need 10 videos to cover it all (please give the arthropods more videos than them overrated chordates, because of how huge the phylum is).

[@ProfessorDaveExplains]

Yep I think it’s about ten. Working on that now!

Around 1:48, the images for inarticulate and articulate brachiopods are mismatched. The photo on the left (Lingula, with the large peduncle) is an inarticulate, whereas the photo on the right (a spiriferid) is the articulate brachiopod.

I love lamp

[@mun_s_hun]

1:31 the images are incorrectly labeled. Lingula (left image) is inarticulate. The shell on the right has toothed hinges and represents an articulate brachiopod.

Thank you Professor Dave!

hooray, zoology!

Thank you professor ❤

[@donutdude6918]

can you help me settle a debate with one of my friends?
i say that infinity and zero exist in the universe, but my friends say that they're both just concepts that humans made up.
do you know which is more correct?

[@nathangamerdog]

They are things that humans made up to describe a value of a certain thing.

[@donutdude6918]

@@nathangamerdog so are you saying that they do or dont exist?

We have more then 10cm long ones in India not just 30mms

I totally misread "Most are Dioecious" as "Most are Delicious" at first...

Thanks

I super appreciate that Dave decides to continue doing his academic videos. I love the debunks, but I also love the actual academic videos. I think it speaks measures that Dave decides to continue his academic content despite that lower views. It shows is that he isnt in it for the money. What I’m trying to say is good job Dave!!

Hi Professor Dave: Luv your videos and your debunking of pseudoscience. Minor error in a video though, in vid on phylum Brachiopoda you have inverted articulates and inarticulates, calling lingula articulate and platystrophia inarticulate, otherwise excellent vid.

[@mrdhawal6895]

Prof can you please start a course for organic chem of 11th level grade I loved your explaination but haven't got all the lectures I need.🙏

[@blue-cuboid]

Can you review a video called "The Science Cult: Cosmology, Ethics, Legitimation" by Dark Age Theorist? It criticizes Darwinian evolution but isn't full-on creationist, and towards the end it talks about some other topics.

[@jamiegallier2106]

Excellent series. Interesting, regarding the breeding, that some of the species gestate internally after collecting the sperm from the water column.

Is nuclear fusion and fission = nuclear transmutation?
