Question I'm assuming invertebrates have a nervous system which connects their brains to their bodies (for muscle 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)

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... Tiberius47 07:12, 13 November 2006 (UTC)
