Largest living invertebrate?

I will guess some kind of giant octopus.

Excuse me, it's hard to focus on trivia while working on pictures.

What kind of acid?

Heh, I figured you'd be working. Close. It was the squid.

a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base. Acids are proton donors that yield hydronium ions in water solution, or electron-pair acceptors that combine with electron-pair donors or bases.

Which animal produces the biggest baby?

i think the elephant.

Biggest baby?

I'll guess some kind of large whale, perhaps a blue whale.

evo, welcome back! looking forward to seeing the pics.

Whale??

I saw one on the discovery channel. You know what's crazy is the giant squid have shown up to my hometown of San Diego. La Jolla Cove. People are getting freaked out because they are not afraid to approach you and feel you up. The thought of those razor sharp beaks that close to me would scare the bejeezus out of me. It's the first time in recorded history this has happened. Or something like that.

Yes, the blue whale. Well done!

They got an ugly pie hole alright.
