The Chambered Nautilus is an ocean-dwelling mollusk. As a nautilus age, it creates new chambers for its shell, which it then grows into. The nautilus moves through the water with jet propulsion, using the chambers it grew out of to regulate its buoyancy. The shell’s spiral is an approximation of the Golden Ratio, a mathematical relationship found throughout nature, art, and architecture. Sharing the story of this curious creature is a Sci High tradition that inspires students to propel themselves forward and keep growing.
