Further mergers

edit

I realised today that we've got separate articles for biramous and uniramous. Sihce these terms are only meaningful in discussions of arthropod legs, I suggest that their material be brought here as an extra section. I don't know of any good pictures showing a biramous leg, but one would be useful. --Stemonitis 14:06, 13 August 2006 (UTC)Reply

Oppose merger of articles re: segments of insect leg

edit

I opposed these mergers on the respective articles talk pages. I have reverted them all. Squamate 14:29, 14 August 2006 (UTC)Reply

To answer your concerns, a merger need not result in a loss of references - these could easily be brought over to arthropod leg. Nor would there necessarily be any dilution of information, since insects have their own section in that article. The separate articles are stubs and are unlikely to grow into anything much longer. They would however, fit perfectly into the arthropod leg article. I can see little reason for preserving their separateness. --Stemonitis 07:32, 15 August 2006 (UTC)Reply
I agree, they would fit very nicely in this article. IronChris | (talk) 14:15, 15 August 2006 (UTC)Reply

Loss of leg statistics

edit

Mention the average number of legs left for various arthropods by the time of their death. For spiders it seems oh, 7.2, down from 8.0 at birth, (which also mention (8).)

Also mention that it seems like no big deal for spiders to lose a leg or two.

Biramous: humans?

edit

Mention if humans are biramous or uniramous or neither or both. Jidanni 13:28, 15 July 2007 (UTC)Reply

Humans aren't arthropods so it isn't relevant here. Equinox (talk) 17:15, 27 August 2015 (UTC)Reply

What's a "thoracopod"?

edit

Redirects here but not mentioned in article. Equinox (talk) 17:14, 27 August 2015 (UTC)Reply

Inconsistency with modern cladistics in phrasing

edit

A lot (but not all) of this article treats insects as a separate category from crustaceans, including saying that the crustacean naming differs from "other", and so on. But insects are crustaceans. It feels like some editors of this article don't know that. 2601:1C2:5000:E7:3599:CC36:A009:E942 (talk) 01:40, 12 July 2024 (UTC)Reply

Phylogenetically, yes, insects belong in Pancrustacea, but the reality is that there are different systems for naming the parts of the legs of groups of arthropods that were traditionally treated separately. Peter coxhead (talk) 09:28, 13 July 2024 (UTC)Reply
