Description
Nautilus shells and ammonite. 1752 engraving of the shell of a nautilus (Nautilus sp. Fig. 1 & 2) and that of an ammonite (Fig. 3), an extinct relative. When cut open, the shell of a nautilus is seen to consist of a spiral of air-filled chambers. The animal lives in the outermost chamber, building successively larger additions through its life. A tube called a siphuncle links the chambers and keeps them filled with gas, which gives the animal buoyancy in its marine habitat. There are only six living species of Nautilus, descended from a large group that originated in the early Palaeozoic Era.
