Nautilus shell

The Nautilus shell is a naturally occurring, spiral-shaped shell produced by the marine mollusk Nautilus. It exhibits a logarithmic or golden spiral, which allows the shell to grow outward while maintaining its shape. The shell’s interior features chambers that the creature can fill with gas or water, aiding buoyancy and movement in the water. Its beautiful, evenly expanding structure has inspired mathematical study and design, exemplifying efficiency and natural elegance. The Nautilus shell is a remarkable example of nature’s engineering, balancing strength and growth through its precise spiral pattern.
