Neither of the 2 illustrations on the top-right shows a "peritoneum". Maybe someone can find an illustration that does.

Is the Uterus an Intraperitoneal organ ? --Hinook67 (talk) 17:47, 8 October 2009 (UTC)

Why is this article so human-centric?[edit]

Why is only the human peritoneum discussed in this article? I want to know about the peritoneums of other animals. I want to know if all animals have it or if some do not. Also where are we going to put the thousands of additional pages about the anatomy of every other animal that has one?

This article should be discussing the topic in a general way, and the human-specific details can be moved to another article, such as Peritoneum (human).... DMahalko (talk) 19:33, 21 November 2010 (UTC)

I think you'll find the first sentence goes a long way to answering your question on which animals have peritoneum:

The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom — it covers most of the intra-abdominal (or coelomic) organs — in higher vertebrates and some invertebrates (annelids, for instance).

I'd say much of the content is anthropocentric simply because the veterinarians and zoologists haven't edited the article much. I would suggest that if you went and created a bunch of articles about the peritoneum of every animal that posesses one, and stripped this one done to a general discussion only, we'd end up with a bunch of stub or start class articles that people would pretty soon be suggesting a merge of. I think the better way to go would be to create subsections in this article for the various animals involved, then invite people who edit veterinary or zoological articles to contribute. Perhaps you could post such an invitation at WP:BIOLOGY or WP:Animals, for example. Cheers, Mattopaedia Say G'Day! 02:58, 22 November 2010 (UTC)


The statement/implication that a peritoneum appears only in amniotes and invertebrates seems WAY off the wall to me. Not sure where that could have even come from. — Preceding unsigned comment added by (talk) 11:40, 12 May 2013 (UTC)
