The '''nautilus''' or ''chambered nautilus'' is a sea animal. It is a cephalopod, like the squid, octopus, and cuttlefish. It grows a large, beautiful spiral shell. The shell is lined with glistening [[mother-of-pearl]]. As it grows, it builds partitions which divide the shell into chambers; it lives in the outermost partition. These shells were common decorations in Victorian England and the United States. | The '''nautilus''' or ''chambered nautilus'' is a sea animal.
