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.

What is the apostrophe in The Chambered Nautilus?
"The chambered Nautilus" doesn't have an apostrophe.
Why is the chambered nautilus buoyant?
The chambered nautilus is buoyant because it has a gas-filled chambered shell that helps it float in water.
How does a chambered nautilus control its buoyancy in its natural habitat?
The chambered nautilus controls its buoyancy by adjusting the gas and liquid levels in its chambers. By regulating the amount of gas and liquid in its chambers, the nautilus can change its buoyancy and move up or down in the water column.
How long has chambered nautilus been around?
The chambered nautilus has existed virtually unchanged for 500 million years.
How does a chambered nautilus control its buoyancy in the ocean?
The chambered nautilus controls its buoyancy in the ocean by adjusting the amount of gas in its chambers. When it wants to rise, it releases gas from its chambers, and when it wants to sink, it adds gas to them. This allows the nautilus to move up and down in the water column.
Does a chambered nautilus prey on other animals?
A chambered nautilus has predators such as the octopus, triggerfish, shark and sea turtle.
What structure is used by the chambered nautilus for buoyancy?
The chambered nautilus uses gas-filled chambers within its shell to control its buoyancy. By adjusting the amount of gas within these chambers, the nautilus can regulate its position in the water column.
What is the unique characteristic of a chambered nautilus?
it has chambers
What is the only cephalopod that has retained an external shell?
The only extant cephalopod that produces an external shell is the chambered nautilus. The shells produced by squid and cuttlefish are internal.
How many chambers do the chambered nautilus have?
8 chambers!
The nautilus is the only living cephalopod with?
A chambered shell
Should you save the endangered chambered nautilus?
yes
