Talk:Malpighian tubule system

Untitled
some more mention of malpighians in arthropods other than insects (Crustacea, Chelicerata)appreciated Goldfinger820 03:40, 17 April 2006 (UTC)


 * Erm, I don't think any other phyla besides the insects and myriapods possess malpighian tubules... In fact I'm going to change that in the article; please correct me if I'm wrong. Iron C hris |  (talk) 03:47, 3 May 2006 (UTC)


 * Arachnida definitely do, but not sure about crustacean orders - hopefully someone in this area can help out (i have a feeling they dont though...) Goldfinger820 05:58, 3 May 2006 (UTC)


 * mmmh I read somewhere that the organs in spiders and not homologous but rather some kind of convergent evolution... It's incredible how difficult it is to get clear information about malpighian tubules! I'll try to ask my Master's supervisor this afternoon. Iron C hris |  (talk) 13:18, 3 May 2006 (UTC)


 * Ok at last some information on the subject. I added what I found out. It would need a citation though, I'll try and browse some journals to find an article. You want to know something funny? I had an exam in a course called "invertebrate diversity" today, actually my last undergraduate exam, and one of the questions was "define Malpighian tubules"! Well, that wasn't too difficult! Take care, Iron C hris |  (talk) 03:31, 4 May 2006 (UTC)

ok um this site kinda helped me but......not really. why the hell cant it just tell me the function of the fricken malpighian tubules! i dont need all that other info, its not like anybody is really that interested in grasshopper anatomy anyways! lol


 * haha - the greatness of Wikipedia hope you did well  Goldfinger820 05:23, 4 May 2006 (UTC)

Waste products
The article presently states:
 * The wastes then are released from the organism in the form of solid nitrogenous compounds as calcium oxalate.

I'm no chemist, but the page for [[calcium oxalate]] gives a chemical formula of CaC2O4, which clearly lacks any N.

How can a compound that has no nitrogen be nitrogenous?
