like other cephalopods the nautilus moves via "jet propulsion" by shooting water out of its hyponome (funnel). Unlike other cephalopods it lives in a hard shell and therefore does not have a muscular mantle. Instead it has a flap on its hyponome that when it is closes increases the velocity of water moving out the funnel. This is analogous to placing your thumb over the end of a garden hose.
