Talk:Gastropoda

message: I was preparing a page on the family Barleeidae, order Neotaenioglossa, when I saw that I could not make a link to Gastropoda.
I know, the classification of Gastropoda is rather confused.
But I think a reworking of this page is in order.
I am loath to interfere with your work. There I want to leave it up to you.
Take a look at the website : 
University of Michigan
and you will see that things are looking there quite different from this page at Wikipedia.
There is also another classification going on. I think this may be even the newest classification.
See following website : 
The author of these last website can be reached by email on : 
mkosnik+gbrdb@alumni.uchicago.edu 
Perhaps he can bring a bit of order in this confusion.

thread_title: A note

message: I took the plunge and made an article on this new taxonomy down to the level of family, placed temporarily on my user page User:JoJan/Taxonomy. This is an umbellished article without much explanation and without synonyms or author names. If necessary, these data can be added into the articles about the taxa. 
 
I invite every collaborator of the gastropod project to look at it closely. Even at first sight, the differences with the taxonomy of Ponder & Lindberg (1997) are considerable. This new taxonomy has tried to reconcile the recent advances by using unranked monophyletic clades for taxa above the rank of superfamily (replacing the ranks suborder, order, superorder and subclass), while using the traditional Linnaean approach for all taxa below the rank of superfamily. Whenever monophyly has not been tested or is known to be paraphyletic or polyphyletic, the term "group" or "informal group" has been used.
This poses a big problem for all our existing articles and taxoboxes. Between class and superfamily there are no other ranks left in the new hierarchy except clades or "informal groups". I wonder how we are to deal with this. 
After some considering, I propose to leave the taxoboxes as they are, except when a name has become invalid, e.g. Pseudothecosomata, a suborder that has become the superfamily Cymbulioidea. I haven't moved this article yet to the new name Cymbulioidea until we have reached some agreement. And I suppose there will be numerous other cases to be dealt with.
Furthermore, I propose to put the taxonomy of Ponder & Lindberg from its place in the article Gastropoda into its own article Taxonomy of the Gastropoda - Ponder & Lindberg (1997) (unless someone proposes a better name) and leave in the article Gastropoda under the header "taxonomy" a link and some explanation. The same goes for the new taxonomy : Taxonomy of the Gastropoda - Bouchet & Rocroi (2005) and again leave a link and some explanation in the article Gastropoda.

replies: text: Thank you JoJan for doing this (and for letting me know about it.) I feel this is an excellent addition both to the project and to the encyclopedia as a whole. I agree with your suggestions for how to entitle both this one, and the other new article you would create by moving the Ponder and Lindberg taxonomy to become its own article. As for the taxonomy itself, it will take me some time to get a feel for it, but I think it is an interesting new approach. Invertzoo (talk) 15:07, 3 January 2008 (UTC)

text: Me again. We will have to see how the malacological community receives this taxonomy and what the upcoming Ponder and Lindberg 2008 paper ends up looking like. But if this kind of system does win out in the end and stabilizes, I assume we will just have to redo the basic taxobox with slots for clades and informal group, in between rankings for class and superfamily.

message: There is considerable discrepancy between the § Respiratory system  …The respiratory protein in almost all gastropods is hemocyanin, but a pulmonate family Planorbidae have hemoglobin as respiratory protein…and:… Hemoglobin is present in the hemolymph as the respiratory pigment... in the following § (which needs to be expanded).
Also: nudibranch denotes a shell-less animal with nude gills. The …rosette of feathery plumes on their backs… is usually towards the tail-end, hence Opisthobranchia. Tusbra (talk) 16:28, 8 May 2009 (UTC)

message: I think anyone who is taking a serious look at gastropods in a post-secondary education fashion will more than likely be interested in their neurological aspects. Historically, seaslugs have been used for neuroscience research, especially Lymnea in relation to examining long-term potentiation. I don't think people use gastropods for too many other fields of research, which is why I boosted up the nervous system and sensory category to a higher place in the article. --Cyberman (talk) 07:09, 31 March 2011 (UTC)

message: "...described under the vernacular (French) name "gasteropodes" by Georges Cuvier in 1795." No, the French vernacular is escargots. In French the rather literary gasteropodes is a term that follows Cuvier, not one that precedes him. Someone may want to fix this. --Wetman (talk) 19:45, 6 October 2012 (UTC)

message: The traditional taxonomy is (at least potentially) comprehensible to interested lay (non-scientist) readers. OTOH, cladism is, and will remain, incomprehensible to the majority of readers.
So now we have reached the point, in Wikipedia, where there are only kingdom, phylum, class (if that) and nothing else? No orders or genera?
Also, where in the Bible or the Constitution, on what set of stone tablets, is it inscribed that the only valid categorical systems are those based on genetic family relationships?
IMHO, cladists are all crazy even when they're technically correct. But more importantly, they're speaking only to each other. Is Wikipedia an encyclopedia for the broadly educated public, or a preening ground for arch-specialists to signal their arcane virtue to each other?  — Preceding unsigned comment added by 74.104.101.14 (talk) 19:53, 29 November 2017 (UTC)

message: I removed this paragraph "However, this "rotation hypothesis" is being challenged by the "asymmetry hypothesis" in which the gastropod mantle cavity originated from one side only of a bilateral set of mantle cavities." because the reference is now seventeen years old, and this issue must have more recent references. Did the challenge succeed? Did the challenge fail? What is the current most accepted hypothesis about the evolutionary origin of the gastropod mantle cavity?
