Talk:Bivalvia

Gills

In the anatomy section there should be discussion on the gill morphology. Gibby is gibby (talk) 15:26, 26 March 2009 (UTC)[reply]

Extra information

Added further information. The new text needs links to other articles added. Dlloyd 10:09, 27 Jul 2004 (UTC)

Anatomy

I think this article needs to include more bivalve anatomy. It's hard to think of these things without any head or body parts as relatives of snails and octopodes. What body parts make them up besides a mantle and a foot?

Spine

The article currently reads:

Additionally, bivalves became mobile: some developed spines for buoyancy, while others suck in and eject water to enable propulsion.

The link being to spine (anatomy), which is actually a redirect to vertebral column, which is surely not what is intended! This needs to be changed, but to what I am not sure. --Iustinus 16:40, 6 September 2006 (UTC)[reply]

I noticed this too. I removed the link, since I don't know where it should point. I am curious how spines increased bouyancy, and it would be nice if someone could explain.

Oops

big ass? (see 1st sentence, 3rd paragraph) "Bivalves lack a radula and feed by siphoning and filtering big ass particles from water."

Question

Do bivalves change sex during the course of their life?

They are overwhelmingly gonochoristic but a few are hermaphroditic, but don't know which ones are.Esoxid^t 22:19, 22 September 2008 (UTC)[reply]

Shells

It would be nice to have more information about bivalve shells, as a parallel to Gastropod shell -- both are linked as main articles from Animal shell. Thanks! — Catherine\^talk 15:41, 23 June 2007 (UTC)[reply]

Systematics

I'll be revising this when I have some spare time. I'm doing research on bivalve phylogenetics and checked here just out of curiosity to see what classification scheme was used. I'm even unsure of what the most accepted phylogeny is, as of yet, but I know it is very different from Carter's 1965 system in terms of subclasses and orders. I believe it is broken into two superclasses (Protobranchia(Nuculoida,Solemyoida,Nuculanoida) and Autolamellibranchiata(Pteriomorphia and Heteroconchia(Palaeoheterdonta,Heterodonta))). I also added the line about Anomolodesmata being an order within Heterodonta. Esoxid^t 22:58, 26 September 2008 (UTC)[reply]
