[edit] Questions

I'm assuming invertebrates have a _nervous s

[edit] ystem

which connects their brains to their bodies (for bitchy movement, sensation, regulatory functioning, et cetera), just no spine for housing?  Is that correct?

In those animals big enough to have a nervous system, yes. Smaller animals, such as protists, have no need for a nervous system. But, in principle, yes, invertebrates have nervous systems that can be exceedingly complex - note the intelligent behaviour exhibited by octopi. See chordate for information about the spinal column. --Stemonitis 08:29, 28 Apr 2005 (UTC)

Most invertebrates have nervous systems, except a few like sponges. It doesn't really matter if they are large enough or not. Also, protists aren't animals, so none have nervous systems. Richard001 08:17, 29 October 2007 (UTC)

What are some advantages that invertebrates have over vertebrate animals?

for one, arthropods can fall great distances (relative to their size) without getting hurt) due to having their bones on the outside. --Philo 23:30, 27 August 2006 (UTC)

[edit] Stub

For a page on such a huge group of creatures, this page certainly is short! i think it deserves a stub warning thingy. I'd add it myself, but as a brand new user, I have no idea how... BLAH BLAH BALH Tiberius47 07:12, 13 November 2006 (UTC)

• It's probably closer to a start class article, and overlaps a lot with animals (which, to a very good approximation, are all invertebrates), but it is very important and does need a huge amount of work. A pity that we still have so few biology editors. Richard001 08:11, 29 October 2007 (UTC)

[edit] Can anyone help my project?

I know this page is not for this, but I think the project I started could help, so, can someone help. —Preceding unsigned comment added by Jourdy288 (talk • contribs) 01:37, 18 January 2008 (UTC)
