The Nautilus

The nautilus is a marine mollusk with a distinctive, coiled shell that provides buoyancy and protection. It belongs to the cephalopod family, related to squids and octopuses. The shell is divided into chambers; the nautilus moves between these chambers to regulate its buoyancy, allowing it to glide through the water efficiently. Its soft body resides inside the outer shell, with tentacles used for sensing and capturing prey. Nautiluses are deep-sea creatures, and their intricate shells have inspired designs in architecture and engineering due to their natural logarithmic spiral pattern.
