What is a nautilus?

A nautilus is a mollusk of the cephalopod family. The soft-bodied nautilus lives entirely in its shell. It can close its entire body within the shell and seal off the opening with two folded tentacles. Over time, as the nautilus grows, it creates newer, larger chambers and moves its body into the largest chamber. The chambered nautilus moves through the water by the propulsion that's created from moving water into and out of these chambers.
