Taking out the evolution part you retards, it was proven false by Shane Maxey, the great scientist of Maryland citation needed. — Preceding unsigned comment added by 216.228.179.68 ( talk) 04:22, 23 November 2012 (UTC)
My additions are a laywoman's attempt to organize what I'm finding on the web as I fill in basic articles on the arachnids, and to make it searchable and readable for other laymen. Experts, please correct me where I have erred! Catherine
Shouldn't it be "pseudoscorpions"? 69.133.143.122 00:49, 4 June 2007 (UTC)
What's going on with this red X pink futile struggle? Is this guy doing it on purpose to vandalize or he is just unaware of the color convention of the taxoboxes? Vae victis 22:25, 16 May 2006 (UTC)
We should be cautious about phrases such as cephalothorax is formed by fusion of a cephalon plus thorax. There is no evidence that Chelicerate ancestors ever had a thorax. There is no post-cephalic tagmosis reported in the Arachnata. We should rather say something like: the cftx is formed by the anteriormost trunk segments fused to the head and serves to sensory and locomotory functions. Vae victis 01:39, 6 May 2006 (UTC)
At least mites, daddy longlegs, uropygids and some spiders are not poisonous (that's what I found browsing around). Should it be added that almost all arachnids have 8 legs? The only exception I found is that occassionally the front-most pair is converted to sensory function.

The link nymphs connects to the mythological nymph rather than biological one. I'd fix it, but I don't know how. :/ —The preceding unsigned comment was added by 24.19.80.47 ( talk • contribs) 00:11, 3 September 2004.
I removed this section from the article:
Developed by Max Vision's White Hats, ArachNIDS is an attack profile database used to dynamically create signatures which are compatible with various Network IDS. I'm not sure whether to consider it spam. Maybe it's useful for something, but it certainly does not make a good first paragraph for this article. Rl 18:58, 20 August 2005 (UTC)
I also perceive this as spam. Vae victis 01:43, 6 May 2006 (UTC)
I'm removing the {{Image requested}} template because I've added images from other articles. You may want to add other images as the article gets longer and has more space for them. delldot | talk 18:14, 12 December 2005 (UTC)
Does this mean there are some arachnids that do not lay eggs, and rather use some other mechanism? Which are they? They sound interesting to me... - JC 02:51, 23 February 2006 (UTC)
The article says 'Arachnids are named after the mythological figure Arachne.' However, the linked article on Arachne says 'Arachne's name simply means "spider" (αράχνη)'. So I find it much more likely the name of the class is derived from the Greek word for spider. Can anyone please confirm? I'd like to change it, but I must be sure. Jalwikip 11:17, 16 July 2007 (UTC)
Hi there,
I was reading this article today - very nicely written by the way - and I noticed several inconsistencies that I thought I would point out and let someone else correct (since this is not my article I didn't want to do it). I hope I'm not being to forward or nasty - I'm only trying to improve the article.
The systematics are listed like this:
* 2.1 Acarina * 2.2 Amblypygi * 2.3 Araneae * 2.4 Haptopoda * 2.5 Opiliones * 2.6 Palpigradi * 2.7 Phalangiotarbida * 2.8 Pseudoscorpions * 2.9 Ricinulei * 2.10 Schizomida * 2.11 Scorpions * 2.12 Solifugae * 2.13 Trigonotarbida * 2.14 Uropygi
However, the phylogenetic tree looks like this: †Trilobita Xiphosura Eurypterida Arachnida Scorpiones Opiliones Pseudoscorpiones Solifugae Acari Palpigradi Pycnogonida †Trigonotarbida Ricinulei Araneae Amblypygi Uropygi Schizomida
Thus, by my reckoning (and assuming the † is a reference to extinct), the following corrections should be made: 1) Acarina should be made consistent with Acari - no preference which. 2) Haptopoda needs a place on the phylogenetic tree. 3) Phalangiotarbi needs a place on the phylogenetic tree. 4) Trilobita probably deserves it's own section in the main article given it's distinct order. 5) Xiphosura, due to it's position in the phylogenetic tree, probably also deserves it's own section in the main article. 6) Eurypterida, due to it's position in the phylogenetic tree, probably also deserves it's own section in the main article. 7) Eurypterida probably should be indicated as extinct with the †, based on the article it is linked to.
Cheers, and thanks for taking the time to write such a great article.

I'm not sure if this is common to all arachnids, or only certain species, but apparently young spiders can regenerate lost limbs. This seems to be a notable feature. siℓℓy rabbit ( talk) 05:08, 4 July 2008 (UTC)
Hi, I've just made serious revisions to Chelicerate (start-class, I'll submit it for GA review when I've written a lead) and Spider (threatened with loss of its GA status due to lack of refs). Arachnid is in better shape than the other 2 were (B-class) but takes a different approach from the one that comes naturally to me, so I'm reluctant to charge in (my main interest is paleontology, so body plan, fossil record and phylogeny tend to be my focus). However I think Chelicerate and Spider have some content and refs that might be useful in Arachnid - feel free to copy and adapt. -- Philcha ( talk) 11:40, 24 October 2008 (UTC)
This link- http://marlonstein.com/fotos/album/Aracnideos/ should be removed, with few photos without proper descriptions 62.121.89.177 ( talk) 16:22, 26 May 2009 (UTC)
I think that there should be either a small section or just a mention of arachnophobia, being that it is the most common phobia in the world. —Preceding unsigned comment added by 96.41.125.72 ( talk) 07:01, 13 March 2011 (UTC)
Similar how the 8 leg comment says "occasionally the front-most pair is converted to sensory function." Occasionally other organs can grow large enough to look like an extra pair of legs too, like in Solifugae. Considering there's a thousand described species, I think it's worth an extra sentence, if you disagree, feel free to revert me.. Vespine ( talk) 21:55, 16 January 2012 (UTC)
It seems to me that this article is ready for a GA review; it looks like a "good article" to me. After reviewing the nomination procedure, I chickened out - but still recommend. ~E 74.60.29.141 ( talk) 17:29, 22 October 2012 (UTC)
How comes the english Wikipedia credits Lamarck 1801 instead of Cuvier 1812? Are there any sources for that? I would go rather with something like this Animal Biodiversity, Magnolia press 2011. In many other sites: (French, German,... Wikipedia, WoRMS, Cuvier is mentioned. What am i missing here? If there are valid reasons why Lamarck has to be preferred, then Wikipedia sites in other languages could go with that as well. Or just mention both of them. Though, i found that source which suggests Lamarck. — Preceding unsigned comment added by PhilippMontazem ( talk • contribs) 16:32, 17 October 2014 (UTC)
I have serious concerns about the Systematics section of the article.

Did anybody else notice that the second sentence says "All arachnids have eight legs," while the very first sentence of the first section (anatomy) starts off with "Almost all adult arachnids have eight legs." Even though the second sentence of the article comes with the qualifier that the front legs have become sensory appendages, it still implies that those sensory appendages are part of the count to eight. That would mean that "all" and "almost all" are mutually exclusive in their contexts. May I recommend that the second sentence of the article be changed to "Almost all arachnids have eight legs?" It's notable that mites, though all arachnids, sometimes have six or even four legs, depending on the subspecies. So "Almost all" is the correct qualifier. 50.165.125.242 ( talk) 14:47, 3 January 2015 (UTC)

I rated this article "start-class" because it could do with A LOT more material. Some might say that all the necessary material can be found on other articles such as spider, scorpion, etc., but a summary of the important traits of the lower taxa (and in particular the common traits of all arachnids that can be seen in each group) with a link to the main article would be good. As it is, this article does not provide a great deal of information for those who are looking for general information about arachnids. It also lacks images.

Numerous phylogenetic studies have placed Xiphosura as the sister group to all other arachnids. I'd be cautious about claims that they are nested within Arachnida based on a single new study that apparently disagrees with all that have come before it. — Preceding unsigned comment added by 108.51.174.100 ( talk) 03:50, 1 March 2019 (UTC)
