Requested move
Nemertina → Nemertea - Nemertea is the name used by all modern taxonomists, as far as I can see; Nemertina seems to be out-dated. Stemonitis 16:39, 1 January 2006 (UTC)

Discussion

 * Nemertea seems much more common; used by tolweb.org; most common on scholar.google.com; only term in Valentine's On the origins of phyla. So I went ahead and moved it. Gdr 15:45, 3 January 2006 (UTC)

Anopla
Order or class? Anopla article says class, this says order.RuthieK 14:22, 26 August 2006 (UTC)

Do the nemerteans really have a brain? My text book for my bio class says they have a pair of nerve ganglia and a pair of longitudinal nerve cords. —Preceding unsigned comment added by 143.236.35.201 (talk) 18:47, 13 December 2009 (UTC)

 * Proboscis and feeding
 * Respiration and circulatory system
 * Excretion
 * Nervous system and senses
 * Movement
 * Reproduction and life cycle
 * Ecological significance
 * Interaction with humans
 * Taxonomy
 * Evolutionary history
 * Fossil record
 * Family tree


 * I would move "Interaction with humans" to the end of the article since that seems to be the standard position for it, but otherwise, looks great. --Danger (talk) 22:37, 25 January 2011 (UTC)
 * I usually place "Interaction with humans" at the end, but I think it may work well just after "Ecological significance" as the egg-parasitism of Carcinonemertes spp. is a major part of both sections. Let's see how it works. I'll look for other comments as the article develops. --Philcha (talk) 09:13, 26 January 2011 (UTC)

This is getting better. More need to be done on classification of the various families and orders in his phyla. Also could we get more photos of member species... I have been lookin but it is hard. Bruinfan12 (talk) 05:21, 22 March 2011 (UTC)

Shorten intro, fix images
I suggest to shorten the intro section to 1 or 2 paragraphs (right now there are 6 paragraphs). The idea is to give a brief overview what Nemerteans are. There is quite a bit of detail about the "rhynchocoel", the structure of the Nemertean brain and a discussion of disagreements in Nemertean taxonomy. This is already pretty esoteric stuff most people won't care about. Sorry Nemertean specialists, but even as a biologist I don't need that much detail in an intro section. PS: please note that several images have been screwed up. Thanks! Peteruetz (talk) 22:30, 15 September 2014 (UTC)
 * Images fixed: I had to remove the remnants of the photos entirely. The two photos were deleted from wiki.commons and then removed from the article by a bot. Unfortunately this messed up the article format, as the "Annotated image" box remained. It would be nice if someone can locate similar images with a copyright status that allows uploading to wiki; then everything could be reinserted. 62.107.211.144 (talk) 14:29, 24 October 2014 (UTC)

Why does "Nemertina" redirect here?
Not mentioned in article (though Nemertini is). Spelling error? 86.164.23.31 (talk) 23:18, 21 March 2015 (UTC)
 * I'm pretty sure Nemertina is one of several alternate names for Nemertea, so the redirect is appropriate. But I'm not confident enough to edit the article myself. Looie496 (talk) 14:45, 23 March 2015 (UTC)

Hosts steal from hosts?
The article now (Sept 14, 2017) reads, "Order Bdellonemertea. Includes seven species, of which six live as commensals in the mantle of large clams and one in that of a freshwater snail. The hosts filter feed and all the hosts steal food from them."

So the clams somehow steal food from the nemerteans? Should that read "the commensal nemerteans steal food from the hosts"? I don't have access to the referenced book to check. IAmNitpicking (talk) 15:01, 14 September 2017 (UTC)

Anopla/Enopla and changes in higher rank taxonomy
I am a researcher working with systematics, taxonomy, biodiversity, and I work mainly with marine invertebrates with special research interest in the group Nemertea. At the last conference on nemertean biology in August 2018 a proposal of dismissing the higher ranks Anopla and Enopla was written, resulting in the current taxonomic status visible in WoRMS - the world register of marine species:

http://www.marinespecies.org/aphia.php?p=taxdetails&id=152391

The publication with the proposal is named "Nemertean taxonomy-Implementing changes in the higher ranks, dismissing Anopla and Enopla" and was published in Zoologica Scripta (Vol. 48, nr 1, s. 118-119, ) in agreement with a number of 30+ researchers associated to the group Nemertea. I would like this information to reach wikipedia in a way that makes sense also with regard to the taxonomic history. Therefore, I suggest a change in taxonomy in wikipedia so that it reflects the taxonomy in WoRMS, and that we add information about the taxonomic changes to the pages Anopla and Enopla. I also put this note under Anopla.Malin Strand (SLU) (talk) 15:49, 26 March 2019 (UTC)


 * I've implemented the revised taxonomy for Nemertea as presented on WoRMS, moving the families to the appropriate higher taxa. Unfortunately, pages such as this have few if any watchers and it's best to ask questions at Wikipedia_talk:WikiProject_Animals. In the unlikely event you see this message, we do appreciate input from experts. The WP:COI rules were written to avoid people writing about themselves or their organisations, rather than to discourage experts. —  Jts1882  &#124; talk 15:57, 28 May 2024 (UTC)

Outdated taxonomy
It should probably be updated:

"Based on morphological characteristics, two classes of nemerteans had been previously distinguished: the Enopla with one or more stylets on the proboscis and the styletless Anopla. Recent molecular analyses confirmed that the Enopla are monophyletic but challenged the monophyly of the Anopla. Thollesson & Norenburg (2003) distinguished the Enopla (=Hoplonemertea), which comprise the Monostilifera (with one functional stylet) and the Polystilifera (with several functional stylets). Based on their results, these authors abandoned the Anopla but created the Pilidiophora, which includes all of the Heteronemertea and some former Paleonemertea. The Pilidiophora and the Hoplonemertea form the new clade Neonemertea, which is separated from the remaining taxa previously belonging to the class Anopla, namely the Paleonemertea, which apparently is not monophyletic." 84.214.101.199 (talk) 05:26, 10 December 2019 (UTC)
