It's pretty much an undisputed fact that nautilus are awesome, and the same goes for their siblings, the extinct ammonites. Both are cephalopods with external, chambered shells, but they fall into different subclasses: Nautiloidea and Ammonoidea. How can you tell the difference?

(The first nautilus had straight shells!)
