Nautilus Shell (Family Nautilidae): This nautilus is very similar to the earliest cephalopods, which first appeared in the fossil record 500 million years ago. This cross section through the shell shows the consistent mathematical beauty of so many natural forms, from sunflower heads to the spiral arms of galaxies.
Technically it is a logarithmic spiral or spira mirabilis; the space between successive curves increases geometrically, and the shape of the shell does not change as the animal grows.
Nautilus typically hatch with four chambers in their shell, and may develop up to 30 during their lives. As the nautilus grows septa are laid down, and only the outermost chamber is occupied by the animal. The nautilus then controls the gas and fluid content of the vacated chambers to adjust its buoyancy.
